The circumcision controversy in early Christianity played an important role in Christian theology.

The circumcision of Jesus is celebrated as a feast day in the liturgical calendar of many Christian denominations, while the teachings of the Apostle Paul asserted that physical circumcision was unnecessary for the salvation of Gentiles and their membership in the New Covenant. The first Council of Jerusalem (c. 50) declared that circumcision was not necessary for new Gentile converts, ; , , , , ; ; ; , , , ; ; ; . (as recorded in ); Pauline Christianity was instrumental in the split of early Christianity and Judaism and eventually became Christians' predominant position.Jewish Encyclopedia: Baptism: "According to rabbinical teachings, which dominated even during the existence of the Temple (Pes. viii. 8), Baptism, next to circumcision and sacrifice, was an absolutely necessary condition to be fulfilled by a proselyte to Judaism (Yeb. 46b, 47b; Ker. 9a; 'Ab. Zarah 57a; Shab. 135a; Yer. Kid. iii. 14, 64d). Circumcision, however, was much more important, and, like baptism, was called a "seal" (Schlatter, "Die Kirche Jerusalems," 1898, p. 70). But as circumcision was discarded by Christianity, and the sacrifices had ceased, Baptism remained the sole condition for initiation into religious life. The next ceremony, adopted shortly after the others, was the imposition of hands, which, it is known, was the usage of the Jews at the ordination of a rabbi. Anointing with oil, which at first also accompanied the act of Baptism, and was analogous to the anointment of priests among the Jews, was not a necessary condition." Covenant theology largely views the Christian sacrament of baptism as fulfilling the Jewish practice of circumcision, as both serve as signs and seals of the covenant of grace.

While historically circumcision is not observed by the majority of Christians in most parts of the Christian world, and mainstream Christian denominations neither require it for religious observance nor forbid it for medical or cultural reasons, it is practiced among some Christian countries and communities. Some Oriental Christian denominations retained the practice, as part of a rite of passage. According to scholar Heather L. Armstrong of University of Southampton, about half of Christian males worldwide are circumcised, with most of them being located in Africa, Anglosphere countries (with notable prevalence in the United States) and the Philippines.

Background

There are numerous references in the Hebrew Bible to the obligation for circumcision says: on the eighth day a boy is to be circumcised. and the uncircumcised are to be cut off from the people in Genesis 17:14.Any uncircumcised male, who has not been circumcised in the flesh, will be cut off from his people; he has broken my covenant.

During the 1st century BC, there was a controversy in Judaism relating to whether or not a proselyte who was already circumcised needed to be ritually re-circumcised. This is done via a pinprick creating a drop of blood and is still practiced to this day.

1st and 2nd century AD Judaism Jewish sources vary on whether or not circumcision of proselytes was a universal practice in tannaitic times.

The disagreement centers on the correctness of contradictory passages in the Babylonian Talmud and Jerusalem Talmud and which passage is older. B. Yevamot 46a is summarized as follows: Rabbi Joshua says that if a proselyte is immersed but not circumcised this is valid. Because our mothers were immersed but not circumcised. Rabbi Eliezer says the opposite. Because such was found regarding our fathers. However the sages say both are required.

P. Kiddushin 3:12 (3:14, 64d) is summarized as follows: Rabbi Eliezer says only circumcision is required the same as in B. Yevamot 46a. Rabbi Joshua says both are required.

During tannaitic times uncircumcised semi-converts also existed, see God-fearer and Ger toshav.

Circumcision of Jesus

According to the Gospel of Luke, Jesus was circumcised eight days after his birth, in accordance with Mosaic Law.

Mosaic Law in Early Christianity

Similar differences and disputes existed within early Christianity, but disputes within Christianity extended also to the place of Mosaic Law or Old Covenant in general in Christianity. This is particularly notable in the mid-1st century, when the circumcision controversy came to the fore. Alister McGrath, an intellectual historian and proponent of paleo-orthodoxy, claims that many of the Jewish Christians were fully faithful religious Jews, only differing in their acceptance of Jesus as the Jewish Messiah.McGrath, Alister E., Christianity: An Introduction. Blackwell Publishing (2006). . Page 174: "In effect, they [Jewish Christians] seemed to regard Christianity as an affirmation of every aspect of contemporary Judaism, with the addition of one extra belief — that Jesus was the Messiah. Unless males were circumcised, they could not be saved (Acts 15:1)." As such, they tended to be of the view that circumcision and other requirements of the Mosaic Law were required for salvation. Those in the Christian community who insisted that biblical law, including laws on circumcision, continued to apply to Christians were pejoratively labeled Judaizers by their opponents and criticized as being elitist and legalistic.McGrath, page 174: "Paul notes the emergence of a Judaizing party in the region — that is, a group within the church which insisted that Gentile believers should obey every aspect of the law of Moses, including the need to be circumcised. According to Paul [reference is made to Galatians, but no specific verse is given], the leading force behind this party was James ... the brother of Jesus ..."

Council of Jerusalem

Jerusalem was the first center of the Christian Church according to the Book of Acts, The apostles lived and taught there for some time after Pentecost. James the Just, brother of Jesus was leader of the early Christian community in Jerusalem, and his other kinsmen likely held leadership positions in the surrounding area after the destruction of the city until its rebuilding as Aelia Capitolina in , when all Jews were banished from Jerusalem.

In , Barnabas and Paul went to Jerusalem to meet with the "Pillars of the Church":St. James the Less Catholic Encyclopedia: "Then we lose sight of James till St. Paul, three years after his conversion (A.D. 37), went up to Jerusalem. ... On the same occasion, the "pillars" of the Church, James, Peter, and John "gave to me (Paul) and Barnabas the right hands of fellowship; that we should go unto the Gentiles, and they unto the circumcision" ()." James the Just, Peter, and John. Later called the Council of Jerusalem, according to Pauline Christians, this meeting (among other things) confirmed the legitimacy of the Evangelizing mission of Barnabas and Paul to the Gentiles and the Gentile converts' freedom from most of the Mosaic Law, especially from the circumcision of males, a practice that was considered execrable and repulsive in the Greco-Roman world during the period of Hellenization of the Eastern Mediterranean, and was especially adversed in Classical civilization both from ancient Greeks and Romans, which instead valued the foreskin positively.

The primary issue which was addressed related to the requirement of circumcision, as the author of Acts relates, but other important matters arose as well, as the Apostolic Decree indicates. The dispute was between those, such as the followers of the "Pillars of the Church", led by James, who believed, following his interpretation of the Great Commission, that the church must observe the Torah, i.e. the rules of traditional Judaism, and Paul the Apostle, who called himself "Apostle to the Gentiles", who believed there was no such necessity. The main concern for the Apostle Paul, which he subsequently expressed in greater detail with his letters directed to the early Christian communities in Asia Minor, was the inclusion of Gentiles into God's New Covenant, sending the message that faith in Christ is sufficient for salvation. (See also: Supersessionism, New Covenant, Antinomianism, Hellenistic Judaism, and Paul the Apostle and Judaism).

The decision of the Council did retain the prohibitions against eating meat containing blood, or meat of animals not properly slain, and against "fornication" and "idol worship".Karl Josef von Hefele's Commentary on canon II of Gangra notes: "We further see that, at the time of the Synod of Gangra, the rule of the Apostolic Synod with regard to blood and things strangled was still in force. With the Greeks, indeed, it continued always in force as their Euchologies still show. Balsamon also, the well-known commentator on the canons of the Middle Ages, in his commentary on the sixty-third Apostolic Canon, expressly blames the Latins because they had ceased to observe this command. What the Latin Church, however, thought on this subject about the year 400, is shown by St. Augustine in his work Contra Faustum, where he states that the Apostles had given this command in order to unite the heathens and Jews in the one ark of Noah; but that then, when the barrier between Jewish and heathen converts had fallen, this command concerning things strangled and blood had lost its meaning, and was only observed by few. But still, as late as the eighth century, Pope Gregory the Third 731 forbade the eating of blood or things strangled under threat of a penance of forty days. No one will pretend that the disciplinary enactments of any council, even though it be one of the undisputed Ecumenical Synods, can be of greater and more unchanging force than the decree of that first council, held by the Holy Apostles at Jerusalem, and the fact that its decree has been obsolete for centuries in the West is proof that even Ecumenical canons may be of only temporary utility and may be repealed by disuse, like other laws." The resulting Apostolic Decree in Acts 15 may simply parallel the seven Noahide laws found in the Old Testament, and thus be a commonality rather than a differential. However, modern scholars dispute the connection between Acts 15 and the seven Noahide laws. In roughly the same time period, rabbinic Jewish legal authorities made their circumcision requirement for Jewish boys even stricter."peri'ah", (Shab. xxx. 6)

Teachings of Paul

While the issue was theoretically resolved, it continued to be a recurring issue among the early Christian communities. After the Council of Jerusalem, Paul wrote to the Galatians about the issue, which had become a serious controversy in their region. There was a burgeoning movement of Judaizers in the area that advocated strict adherence to traditional Jewish laws and customs, including circumcision for male converts. According to McGrath, Paul identified James the Just as the motivating force behind the movement. Paul considered it a great threat to his doctrine of salvation through faith and addressed the issue with great detail in Galatians 3.McGrath (2006). Pp 174-175

According to the Acts of the Apostles, chapter 15, the Jewish Christian leaders of the early Church at the Council of Jerusalem rejected circumcision as a requirement for Gentile converts, possibly the first act of differentiation of Early Christianity from its Jewish roots (See also: List of events in early Christianity). The rite of circumcision was especially execrable in Classical civilization because it was the custom to spend an hour a day or so exercising nude in the gymnasium and in Roman baths, therefore Jewish men did not want to be seen in public deprived of their foreskins. Hellenistic and Roman culture both found circumcision to be cruel and repulsive.
