Johannes Marck’s ninth chapter defines angels as created, incorporeal, and finite spiritual substances destined for God’s ministry, possessing intellect, free will, and significant yet limited power. Good angels, confirmed in goodness by a gracious covenant rather than the Mediator, minister to God, Christ, and the church; against Papist doctrine, Marck rejects the Dionysian hierarchy of nine orders, individual guardian angels, and the invocation or religious worship of angels, permitting only respect and imitation. Evil angels, created good but voluntarily fallen through pride or envy before man’s fall, are punished by expulsion from heaven, deprivation of the beatific vision, and diminished power under Christ, with final judgment awaiting them; their state is irreparable by God’s counsel to demonstrate His severity, yet even in their malice they remain subject to the divine will.

Johannes Marck’s tenth chapter defines providence as God’s continuous external action whereby He preserves, cooperates with, and governs all created things unto His glory and the salvation of the elect. Executed by the Triune God through the command of His will, providence excludes fortune and Stoic fate, utilizing secondary means without being bound to them, thus allowing for miracles. Marck details three acts of providence: preservation of essence, concurrence—an immediate, predetermining impulse where God acts as the first cause alongside second causes without destroying rational liberty—and government, which directs all things to their ends. He asserts that providence extends to the greatest and smallest matters, contingent and free events, all good things, and even evils. Regarding evil, he rejects Libertinism, Manichaeism, and Pelagianism, explaining that while God produces the action itself, He does not produce the malice; rather, He permits it by withdrawing grace, increases it through judicial handing-over, limits it, and directs it to His own glorious ends. Far from introducing fatalism, this doctrine provides believers with consolation in adversity, humility in prosperity, and a foundation for hope, diligence, and prayer.

Johannes Marck’s eleventh chapter establishes that true worship must be rendered exclusively to the Triune God with inward soul-readiness, rejecting both human traditions and the Papist distinction between λατρεία and δουλεία to justify the religious veneration of creatures. The sole rule of this worship is God’s law, which Marck divides into positive, forensic, ceremonial, and moral categories. He argues that the forensic and ceremonial laws—given to segregate Israel, restrain sin, and prefigure Christ—have been abrogated under the New Testament, whereas the moral law (the Decalogue) remains a perfect, immutable, and spiritual rule of life. This moral law, inscribed on the human heart at creation and delivered at Sinai, cannot be altered by papal dispensation or “evangelical counsels,” which Marck rejects as incompatible with Christian liberty, gratitude, and the law's perfection. Although no fallen human can perfectly fulfill the moral law—ruling out works of supererogation—it retains perpetual binding force, not as a covenant of life or condemnation for believers, but as an enduring obligation directing their gratitude and revealing both human misery and the perfection of Christ’s righteousness.

Johannes Marck’s twelfth chapter systematically expounds the Decalogue, beginning with its inscription highlighting God’s essence and redemptive acts. The first commandment forbids foreign gods, requiring worship of the Triune God; the second prohibits idolatrous images, commanding spiritual worship; the third forbids taking God’s name in vain while permitting lawful oaths; and the fourth establishes the Sabbath as both ceremonial in its Jewish form and moral in its substance, now observed on the Lord's Day. The fifth commandment requires honoring superiors, who must act worthily; the sixth forbids unjust homicide, permitting self-defense and capital punishment while commanding love; the seventh prohibits adultery and all carnal impurity, commanding chastity; the eighth forbids theft, upholding property rights against Anabaptist communism while commanding almsgiving; the ninth prohibits false witness and all lying; and the tenth forbids inordinate concupiscence. Throughout his exposition, Marck consistently refutes the Socinians, who erroneously claim these moral requirements were merely added in the New Testament, alongside correcting Papist, Lutheran, and Anabaptist errors regarding images, oaths, feast days, and property.

Johannes Marck’s thirteenth chapter defines man as a creature composed of an erect, organic body and a rational, spiritual soul, created by God on the sixth day for the acknowledgment and proclamation of His glory. He argues that Adam was the first man, from whom all humanity descends, with Eve uniquely formed from his rib; against fables of androgyny or pre-Adamites, he maintains that both sexes originate from this single creation event. Marck details the dual nature of man: the body, skillfully made and suited for reason, and the soul, an incorporeal, indivisible substance endowed with intellect, will, and conscience. He refutes materialistic and traducian views, asserting that each soul is immediately created by God and is inherently immortal, continuing to exist after bodily death. The union between soul and body is described as the closest among created things—local, natural, and productive of mutual communication—yet the soul remains distinct, avoiding Pythagorean transmigration, and will ultimately be reunited with its own body at the resurrection.

Johannes Marck’s fourteenth chapter addresses the state of integrity in which Adam was created and placed in the historical Paradise of Mesopotamia. At the heart of this state lies the imago Dei, which Marck defines not as bodily form but as comprising four elements: the spiritual and immortal nature of the soul with its faculties; inherent rectitude, wisdom, and holiness as its chief part; dominion over the creatures; and conditional immortality so long as man did not sin. He firmly rejects the Papistic distinction between “image” and “similitude,” the Socinian reduction of the image to dominion alone or denial of original rectitude, and the Papist doctrine of superadded grace, insisting that original righteousness was natural to Adam’s creation. Upon this foundation, God erected the Covenant of Works with Adam as the federal head of his natural posterity, stipulating perfect, personal, and perpetual obedience to both the moral law and the positive command regarding the tree of knowledge, while promising eternal and heavenly life and threatening death for transgression. This covenant was sealed by sacraments—the tree of life as a pledge of eternal communion with God, and the tree of knowledge as a test of obedience. Although sin antiquated this covenant, rendering it impossible to renew with fallen man, its natural obligation and the condition of perfect obedience for life remain perpetually in force.

Johannes Marck’s fifteenth chapter examines the state of man’s fall, defining sin as a privative defection from the divine law that subjects man to guilt and deprives him of righteousness. He details the first sin of Adam and Eve, who, seduced by the devil speaking through the serpent, violated God’s command through unbelief, pride, and gluttony, thus incurring the curse of death but also receiving the Proto-Gospel promise of grace. From this transgression flows original sin, which consists of both Adam's imputed guilt and inherent corruption—a pervasive depravity of the whole man, enslaving the will and blinding the intellect, propagated by natural generation to all except Christ alone. This inherent corruption is itself proper sin, rendering man morally impotent and subject to the divine curse, from which he cannot be delivered except by Christ. Proceeding from this corruption, actual sins vary in degree and kind—refuting both the Stoic equivalence of all sins and the Papist notion of venial sin—and culminate in the irremissible sin against the Holy Ghost, defined as the malicious rejection of inwardly known evangelical truth, which precludes repentance and forgiveness.

Johannes Marck’s sixteenth chapter addresses the punishment of sin, defining it as an evil inflicted by God because of sin for His glory and for man’s destruction or salvation. He distinguishes punishment from sin itself and emphasizes that all punishment originates from God, applying strictly to rational creatures even though irrational creation suffers collateral effects. The ends of punishment are twofold: the supreme end is the glory of God’s virtues, while the subordinate ends include the satisfaction of divine justice (strict punishment) and man’s salvation (broad punishment, which encompasses chastening, proving, and martyrial suffering). Marck categorizes punishment into temporal—whether bodily (defects, toil, disease, death) or spiritual (corruption, hardening, horror of conscience)—and eternal. Against the Socinians, he argues that eternal punishment is not annihilation but consists of exclusion from God, desperate sense of wrath, and intense physical pain, necessitated by the wounding of God’s infinite majesty. Finally, he notes that Christ, as the Surety of the elect, endured the constitutive evil of this punishment—spiritual death in dereliction and the kind of eternal and infernal death—though not its endless duration.

Johannes Marck’s seventeenth chapter examines the Covenant of Grace, defining it as a gracious, mutual agreement between God and elect sinners, declared through the Gospel rather than the law. He asserts that this covenant, initiated immediately after the Fall with the Proto-Gospel, is one in substance across all ages, granting Old Testament saints the same Mediator, spiritual promises, and saving faith as those under the New Testament, against the errors of Socinians and Papists. Rejecting the modern trichotomy of economies and the essential distinction between “covenant” and “testament,” Marck upholds the traditional dichotomy of Old and New Testaments, which differ not in substance but in their administration and circumstances. The Old Testament economy spans from Adam to Christ with progressive stages, while the New Testament, inaugurated by Christ’s incarnation and consummated by His death and resurrection, brings greater clarity, liberty, and extent to the same covenant of grace.

Johannes Marck’s eighteenth chapter examines the Mediator of the Covenant of Grace, defining Him strictly as one who makes satisfaction to God’s justice and applies efficacious grace to man, a necessity arising from divine justice and human misery. To accomplish this, the Mediator must be both true God and true man in one person, and absolutely holy—qualifications uniquely fulfilled in Jesus Christ as proven by His doctrine, miracles, and precise fulfillment of Old Testament prophecies concerning His timing, birthplace, Davidic lineage, and virgin birth. Marck counters Jewish objections regarding the spiritual nature of the Messiah's kingdom, Socinian denials of the necessity of satisfaction, and Papist additions of saintly mediators, asserting that Christ alone mediates according to both natures and exclusively for the elect. Finally, he explains that Christ was constituted as Mediator by an immutable, eternal covenant of suretyship between the Father and the Son, wherein the Father stipulates obedience and the Son agrees, a pact historically manifested through prophecies, types, and the incarnation.

Johannes Marck’s nineteenth chapter examines the person of Christ, detailing His names, natures, and the effects of their union. He explains that “Jesus” denotes His saving work and “Christ” His anointing to the threefold office, while His divine nature and true, integral human nature—complete with a soul and human will, yet impeccable—refute the Docetae, Apollinarists, and Remonstrants. Christ assumed flesh from the Virgin Mary by the Holy Spirit's supernatural power, preserving Him from Adamic guilt, and was incarnate solely for man's salvation, against the Socinians. The heart of the chapter defends the hypostatic union, affirming that the two natures are united indivisibly and inseparably, yet unchangeably and without confusion, thereby rejecting both Nestorianism and Eutychianism. Finally, Marck outlines four effects of this union: the communication of charisms, theandric works, idioms (predicated of the concrete person, not the abstract nature, against Lutheran ubiquitarianism), and divine honor, which is due to Christ’s person as Mediator on the foundation of His divine nature.

Johannes Marck’s twentieth chapter details the threefold office of Jesus Christ as Mediator—Prophet, Priest, and King—which corresponds to humanity’s threefold misery of ignorance, guilt, and servitude. As Prophet, Christ infallibly reveals God’s will, a doctrine confirmed by miracles and applied with internal power, an office He has exercised in all ages. As Priest after the order of Melchizedek, Christ both offered Himself as a substitutionary satisfaction for the sins of the elect alone—refuting the Socinian denial of oblation and the Arminian assertion of universal redemption—and continually intercedes for them, rendering any papal or saintly intercession superfluous. Finally, as King, Christ wields a spiritual, eternal, and mediatorial dominion over the Church, governing and defending His people; Marck emphasizes that Christ is the sole Lord and Lawgiver of the Church in both testaments, firmly rejecting Papist hierarchies and the notion that Old Testament believers were subjected to the lordship of angels or human priests.

Johannes Marck’s twenty-first chapter examines the twofold state of Jesus Christ necessary for salvation: exinanition (humiliation) and exaltation (glorification). The state of exinanition, which primarily concerns the human nature, consists of six degrees: the humble incarnation, the toilsome life, the grievous and voluntary bodily passion, true bodily death, burial, and the spiritual death of infernal pains under divine wrath, which Marck identifies as the true meaning of Christ’s descent into hell against Papist and Lutheran errors. He firmly rejects the Theopaschite claim that the divine nature itself suffered. The state of exaltation, wherein the human nature is crowned with the highest finite glory, unfolds in four degrees: the resurrection of the same yet immortal body for our justification; the ascension as a local transfer of the humanity to heaven, refuting Lutheran ubiquity; the session at God’s right hand, signifying supreme majesty and the administrative manifestation of His kingdom; and the last judgment, the final degree of Christ’s glory as the God-man.

Johannes Marck’s twenty-second chapter addresses the two duties of the Covenant of Grace—faith and repentance—which he terms “conditions” not because they are achieved by human strength or serve as the foundation for the right to life, but because God requires them of those in covenant with Him, that they might gratuitously obtain salvation. Faith, the first duty, is categorized into four species: the faith of miracles, historical faith, temporary faith, and saving faith. Saving faith, belonging exclusively to the elect, is defined as a permanent habit of mind wrought by the Holy Spirit through the Word and sacraments, by which believers acknowledge, embrace, and apply the promises of the Gospel. Its three essential acts are knowledge (refuting the Papist commendation of implicit faith), assent or embracing (both theoretical and practical, whereby Christ and his righteousness are received), and fiducial application (a confident applying of the promises to oneself, opposed by the Papists). This saving faith, which justifies by embracing Christ’s priestly righteousness, cannot be totally or finally lost, and it necessarily produces the fruits of hope and charity, though charity must not be conflated with faith's essence. Repentance, the second duty, is similarly a permanent habit of mind divinely infused in the elect, consisting of three principal acts: the acknowledgment of sin, godly sorrow for it, and a turning from sin toward piety. Marck firmly rejects the Papist sacrament of penance with its requirements of contrition, auricular confession, and human satisfaction, asserting instead that the fruit of repentance is the remission of sins and salvation by divine grace alone, not by any intrinsic merit of the act itself.

Johannes Marck’s twenty-third chapter addresses effectual calling, the first of the four principal benefits of the Covenant of Grace, by which God internally and irresistibly transfers the elect from their natural misery into communion with Christ. Distinguishing this internal calling from the external call of the Word which extends to the reprobate, Marck asserts that effectual calling is exclusively for the elect, refuting the Pelagian and universalist extension of a sufficient calling to all. In this transfer, the elect are considered entirely as sinners standing passively, devoid of any prior merit, disposition, or cooperation, as God works hyperphysically and insuperably upon them. Against the Pontificians, Socinians, and Synergists who argue for a resistible grace, Marck contends that God’s operation in calling cannot be frustrated by human impotence, but rather perfectly determines the will unto good. This immutable calling, grounded in God’s grace and Christ’s merit, inevitably produces the fruits of faith and repentance, thereby leading to the glory of God and the certain salvation of man.

Johannes Marck’s twenty-fourth chapter defines justification as a perfect, instantaneous, and forensic act of God's grace, distinct from sanctification, by which the elect are absolved from all sins and adjudicated to eternal life. The sole meritorious cause of this benefit is the imputed righteousness of Christ—his active and passive obedience—apprehended by faith alone, entirely excluding human merit or inherent righteousness. Marck firmly refutes the Papists, who mix faith with works and human satisfaction; the Socinians, who substitute human obedience for Christ’s satisfaction; the Arminians, who make faith and new obedience the foundation of life; and Osiander, who erroneously posits the indwelling essential righteousness of God as the ground of justification. Because it is founded solely on Christ’s perpetual righteousness and God’s irrevocable grace, justification grants the believer subjective certainty, spiritual peace, and the absolute assurance of salvation.

Johannes Marck’s twenty-fifth chapter defines sanctification as the internal, progressive renewal of the whole man—soul and body—by which the Triune God, through the Spirit and the means of Word and sacrament, frees the elect from the corruption of sin and conforms them to the divine image. Unlike justification, sanctification is imperfect in this life, as even the regenerate retain the flesh and struggle against sin, a reality Marck defends against Pelagian and Papist claims of attainable perfection. This inherent holiness manifests in truly good works, which are actions performed according to God’s revealed will, from faith, and by the Spirit’s grace unto God’s glory. While good works are necessary for salvation by precept and means, Marck firmly rejects any notion of merit, asserting that sanctification remains incomplete until death and serves ultimately to humble the believer and magnify divine grace.

Johannes Marck’s twenty-sixth chapter details five religious duties, preeminent among which is prayer—a necessary act of the sanctified directed to the Triune God alone with reverence and confidence, seeking both spiritual and corporal needs, and perfectly modeled in the Lord’s Prayer. Accompanying prayer are fasting and watching, defined as religious abstinences from food and sleep respectively, intended to subdue the flesh and inflame devotion rather than to merit grace as the Papists erroneously assert. Almsgiving is presented as a necessary work of charity toward the needy—especially the faithful—administered from honest means for God’s glory, excluding sturdy beggars and rejecting the Papist notion of satisfaction. Lastly, a vow is a religious promise made to God alone concerning something good, possible, and determined; evil, impossible, or rash vows (including Papist monastic vows) are firmly condemned, while legitimate vows must be faithfully fulfilled unto God’s glory.

Johannes Marck’s twenty-seventh chapter addresses preservation, the fourth benefit of the Covenant of Grace, by which the Triune God inwardly fortifies the elect through the Spirit, Word, and sacraments, and outwardly restrains their enemies, ensuring they cannot totally or finally fall away from grace. Distinct from common preservation, this special grace is restricted to the elect alone, yet extends to all of them, even the weakest, guaranteeing their certain perseverance. Marckius grounds this doctrine in God’s immutable promises, Fatherly love, Christ’s purchase and intercession, and the Spirit’s sealing, firmly refuting the Papist, Socinian, and Lutheran assertions of possible apostasy. He counters their objections by clarifying that the grievous sins of saints are followed by repentance, Adam lacked preservation promises in his integrity, conditional warnings do not describe true partakers of grace, and exhortations to watchfulness are the very means God uses to preserve his people, unto their salvation and his glory.

Johannes Marck’s twenty-eighth chapter explores four interconnected benefits of the Covenant of Grace—Regeneration, Adoption, Reconciliation, and Liberation—which articulate prior benefits under different aspects. Regeneration is the benefit by which God endows the elect, who are dead in sin, with a new spiritual nature and life through the Spirit and the Word. Adoption follows, wherein God assumes those who are by nature strangers and children of the devil into his family as sons and heirs on account of Christ. Reconciliation is the work of God in Christ, by which the elect, who are by nature his enemies, are brought into a stable peace and friendship with him through his blood. Finally, Liberation, or Redemption, frees the elect from the dominion of Satan, sin, and the curse, vindicating them to God’s service; this constitutes true Christian liberty—exemption from sin's power and subjection to God alone—which upholds rather than subverts civil and ecclesiastical order.
