Genesis 17:9Meaning & Commentary from the Church Fathers

This culminates in His declaration: "And My covenant shall be in your flesh for an everlasting covenant; but the uncircumcised male who is not circumcised in the flesh of his foreskin, that soul shall be cut off from his people; he has broken My covenant" (Gen. 17:13-14).

The Apostle Paul affirmed that this act of circumcision served as both a sign and a seal of faith for Abraham in his uncircumcised state (Rom. 4:11). His primary goal was to illustrate that the calling and justification through faith reign supreme and precede all the statutes of the Mosaic law. Paul seemed to have embarrassed the Israelites into understanding that justification by faith is not a violation of the law, but rather a return to its original intention, rooted before the law was established. He further recognizes another form of circumcision, urging the Jews to abandon their reliance on physical ancestry, writing: "For he is not a Jew who is one outwardly, nor is that circumcision which is outward in the flesh; but he is a Jew who is one inwardly, and circumcision is that of the heart, in the Spirit, not in the letter; whose praise is not from men but from God" (Rom. 2:28-29).

Does he not seek to prompt them toward a more profound understanding of circumcision? He conveys that it should not merely be seen as "the seal of faith in the uncircumcision" (Rom. 4:11), but as a spiritual deed of greater significance. Therefore, it is essential to investigate and understand what spiritual circumcision means, what the physical act symbolizes, and why it was mandated specifically on the eighth day. This inquiry is vital for anyone striving for unity with God through Christ. It follows suit that those who genuinely seek communion with the holy Lord should undertake thorough purification and sanctification.

Let us look to God’s instructions to Moses: "Come down, testify to the people, and sanctify them today and tomorrow, and let them wash their clothes, and be ready for the third day; for on the third day the Lord will come down upon Mount Sinai" (Ex. 19:10-11). Here, preliminary sanctification illustrates God's desire for us to cultivate virtuous inclinations and indicates the physical cleansing required, as the body is the very garment of the soul (Lev. 19:2). Those wishing to commune with the holy God were to be prepared in every way, reflecting the command: "You shall be holy, for I am holy" (Lev. 19:2). Thus, circumcision served as a symbolic act of purification in the flesh.

In reflecting upon the actions that lead to sin, we find that every transgressive act begins with desire. We are enticed by our cravings, which precede our actions and ultimately influence the soul. This is validated by a statement from the Apostle James, who said, "Let no one say when he is tempted, 'I am tempted by God'; for God cannot be tempted by evil, nor does He Himself tempt anyone. But each one is tempted when he is drawn away by his own desires and enticed. Then when desire has conceived, it gives birth to sin, and sin, when it is full-grown, brings forth death" (James 1:13-15).

This reveals how desires sow the roots of iniquity and how sinful pleasures give rise to transgression. Therefore, the Divine Lawgiver instructs that the act of circumcision should take place in the region associated with lustful desires, thereby hinting that purity cannot be attained unless we heed the sharpness of God’s Word and let the Spirit’s sword cleanse us (Heb. 4:12). This entails renouncing all shameful desires and undertaking acts pleasing to God instead of pursuing our selfish inclinations. If true circumcision is understood in this manner, it is fitting to declare, "Circumcise yourselves to the Lord, and take away the foreskins of your hearts, you men of Judah and inhabitants of Jerusalem" (Jer. 4:4).

Those who are circumcised only in the flesh remain bound to physicality, but those who, through faith in Christ, are spiritually circumcised belong wholly to God. Spiritual circumcision, granted on the eighth day, signifies Christ’s resurrection—a clear sign that this spiritual circumcision bestows life and fosters a shared existence with Christ, aligning with Paul’s statement: "For you died, and your life is hidden with Christ in God; when Christ who is our life appears, then you also will appear with Him in glory" (Col. 3:3-4).

It is reasonable to assert that anyone who renounces worldly pleasures for the sake of God must die to worldly ways, as Paul articulates: "But God forbid that I should boast except in the Cross of our Lord Jesus Christ, by whom the world has been crucified to me, and I to the world" (Gal. 6:14). By participating in the Spirit that cleanses us from all impurities, we are transformed to live for God, achieving circumcision on the eighth day for the resurrection of Christ. This act does not occur before the eighth day, as the Holy Spirit is given post-resurrection, exemplified when Christ breathed on His disciples and said, "Receive the Holy Spirit" (John 20:22).

In contrast, the Jews, still bound by the law's punishment, are to be circumcised with a physical knife, whereas we are liberated and purified by the Spirit, which eradicates all spiritual defilement and fosters complete purity through faith. The path to the highest expression of godliness is through true spiritual circumcision, as illustrated by Abraham. At ninety-nine years of age, Abraham’s circumcision law was established as the clearest indication that physical circumcision serves as a precursor to achieving virtue. This indicates that without this purification symbolized by circumcision, one cannot attain spiritual perfection.

The number one hundred signifies consummation, with circumcision preceding perfection, guiding us toward it. The value of spiritual circumcision is not confined solely to this introduction, for it also applies to those free in Christ. A man in Christ is free indeed, liberated from the bonds of sin and the devil, as it is stated (Ps. 2:3), donning the glory and freedom that truth provides. Examining Scripture, we find that this spiritual circumcision on the eighth day is reserved for the liberated, distinguishing it from that of Ishmael, who was circumcised at thirteen. The records indicate that Abraham circumcised Ishmael when he was thirteen years old (Gen. 17:25), which illustrates that those born of the slave woman are outside the benefits reserved for the eighth day.

Moreover, he who rejects the saving message of Christ’s resurrection, intended for the eighth day, does not partake of the spiritual circumcision, nor does he accept the apostolic teachings. In contrast, Isaac, born free, received circumcision on the eighth day, reflecting the true children of freedom, inheritors of the resurrection of Christ. This metaphor extends as we consider the Exodus account when Moses received the directive from God to lead Israel from captivity, mirroring the call to spiritual liberation.

The Lord instructed Moses to inform Pharaoh of the necessity of releasing Israel, yet during their journey, Moses encountered a divine angel intent on his demise. Zipporah swiftly acted, taking a stone to circumcise her son, declaring that this act constituted "the blood of the covenant" (Ex. 4:24-26). The significance here lies in understanding that circumcision protects and preserves Moses, emphasizing that it is not merely the act of circumcision that offers salvation, but the spiritual circumcision—the circumcision of the new people who have believed in Christ—acts as a safeguard against destruction.

One might ask how Israel endures without experiencing this spiritual circumcision, yet we understand that Israel’s rejection of Christ’s resurrection incurs an eternal dominion of death, whereas those who believe receive grace. A profound distinction exists, as unbelievers’ resurrection leads merely to life without faith, resulting in condemnation. In contrast, those who honor the Saviour’s resurrection will emerge in glory, having embraced a life of obedience.

The Spirit invites those spiritually circumcised to extend grace to all. Paul emphasizes, "For just as you were once disobedient to God but now have obtained mercy through their disobedience, even so these also have now been disobedient, that through the mercy shown to you they also may obtain mercy" (Rom. 11:31). This exemplifies that the grace bestowed upon believers also resonates through humanity, as God desires to bring salvation to all.

Furthermore, the Apostle Paul elucidates the mystery of the impending resurrection, asserting that Christ, having risen first, will appear as the firstfruits of those who have died, awaiting His coming (1 Cor. 15:23). Importantly, this resurrection is primarily designated for those united with Him through faith, yet it encompasses the entire creation, revealing God’s benevolence in abolishing death completely.

We see Zipporah circumcising their son with a stone, signifying that this is emblematic of the steadfastness of Christ, who is referred to as an adamantine stone (Am. 7:8). The symbolism indicates the unyielding strength of God’s Word, which grants believers victory over sin. Similarly, after Moses, God raised Joshua to lead Israel into the Promised Land, commanding them to purify themselves through circumcision with knives made of stone, indicating the invincible certainty of God’s promises.

After Moses’ death, knives symbolic of circumcision were entombed with him—a reminder that the grace of spiritual circumcision, providing access to heavenly blessings, is directly linked to Christ’s death. Thus, the circumcision of the eighth day alludes to cleansing through the Spirit, faith, and the resurrection of Christ, signifying a total rejection of sin and offering communion with God.

This discourse reflects the understanding of circumcision in the spirit and its role in the life of believers, showing a parallel between spiritual circumcision and the rest provided through the Sabbath. The seventh day of rest signifies liberation from sin, aligning with the notion that spiritual circumcision embodies freedom from sinful desires. Both highlight the necessity of liberation from evil, revealing their unified purpose—facilitating the fulfillment of God’s law through a righteous life.

Consequently, engaging in circumcision on the Sabbath manifests the alignment of holy acts with rest, underscoring that one’s duties towards God should persist unwaveringly, even during sacred periods. This denotes that true rest means engaging in virtuous works and distancing oneself from evil, availing oneself of the opportunity to nourish one’s spirit genuinely.

In conclusion, while the distinction between physical incapacity to commit sin and the total renunciation of passions through the act of circumcision may seem nuanced, this understanding bears significant implications for spiritual growth. Transitioning from an inactive state of sin to one of completeness requires acknowledgment of the deeper work that Christ does within us, propelling our transformation to live as renewed beings in Him—a journey epitomized in the act of circumcision on the eighth day, the day representative of resurrection and renewal.

If the Jews hold circumcision in high esteem, they should note that it was not only Abraham who was circumcised; so were the half-slave Ishmael, the domestic servants, and the purchased individuals, as well as the Idumeans and the descendants of the Hittites. The Egyptians also adopted this practice from the Israelites. Therefore, it is clear that circumcision does not confer righteousness, as scripture denounces all who are associated with it as wicked. It was not circumcision that justified Abraham, but rather his faith that made him righteous. His virtue earned him glory, while circumcision served solely as a sign of that faith.
