The Jerusalem Diet

The English word diet is derived from a Latin word meaning both “parliamentary assembly” and “daily food allowance.” Although the political use of the word may not be very familiar to us today, it was used for the governing body of the Holy Roman Empire and the most famous Diet was one held in Worms, a city in the German Rhineland. The Diet of Worms was called by Emperor Charles V in 1521 to demand Martin Luther either recant his views or be declared a heretic. He didn’t recant.

The Jerusalem Conference in Acts

Both senses of the word apply to the Jerusalem conference (c. 49 CE) described in Acts 15:1-21. It was a general assembly of the apostles and elders (first- and second-generation leaders of the church) and its final decree dealt with food restrictions on Gentile converts. Paul’s account of the Jerusalem conference and its aftermath are reported in Gal 2:1-14.

In the opening verses of the account in Acts (vv. 1-2), Luke explains that the crisis was precipitated in the Antiochene church when members of the circumcision party arrived teaching that circumcision and observance of the Mosaic law were requirements for salvation. This generated confusion and dissension, so Barnabas and Paul were sent to Jerusalem to consult with the apostles and elders there.

After both sides presented their case (vv. 4-5), Peter spoke of his experience with converts like Cornelius and how he witnessed the Holy Spirit poured out on the Gentile Christians (vv. 7-11). James concluded the conference when he announced his decision (“I have reached the decision,” v. 19) that Gentiles will only be required to abstain from certain foods and improper sexual relations (vv. 13-21). Curiously, both James’ decree and the resulting letter (vv. 22-29) said nothing of circumcision, the driving issue for the conference.

The main image in the St. Peter Window (c. 1870) of the Cologne Cathedral in Germany shows the Council of Jerusalem. Sts. Peter and Paul are the central figures. Peter's stance and gestures indicate he is the more significant figure in the window..

Two Separate Decisions

Biblical scholars believe that Luke is conflating two different decisions by the Jerusalem authorities. In Paul’s description of the council in Gal 2:1-10, the apostolic leaders decided that circumcision would not required of Gentile believers. But in a later decision where Paul was not present, some ground rules based on Lev 17-18 were established for Gentile Christians that would allow them to live and worship alongside observant Jewish Christians.

What evidence do we have for this? Paul reported (Gal 2:11-14) how table fellowship in Antioch was disrupted by insistence from the “men from James” that Jewish believers could not eat with Gentile believers. But the whole point of James’ decision in Acts 15:19-20 was to lay down minimum dietary rules for Gentiles that would allow Jews to be able to join them in table fellowship. It doesn’t make any sense for the James party to insist on separation at meals if the decision of the Jerusalem conference had established rules to eliminate the need for separation.

Not only that, but according to Acts 21:25, on a later visit to Jerusalem (c. 57 CE) Paul is informed by James that a letter was sent listing the four restrictions on Gentile Christians, the same letter that he and Barnabas were supposed to have carried to Antioch (15:25)! But it all makes perfect sense if there were two decrees from the Jerusalem authorities made a few years apart and Luke combined them as the product of one council.

Why No Circumcision?

Why did the pro-circumcision faction lose? The best explanation I’ve seen is that James realized that forcing circumcision and the Mosaic law would have driven away many potential Gentile converts. Although they might then be considered nominal Jews, the Gentiles’ allegiance would be to Christ and not to Moses. When push came to shove and outside persecutions against Jews arose again, the Gentile believers would consider themselves Christians and not Jews, in spite of any circumcision they received. They would not be willing to die rather than denounce the Mosaic law that was forced upon them.

The unspoken flip side of the Council’s decree meant no relaxation of the Mosaic law for Jewish Christians. This was not something Paul agreed to and Peter only accepted grudgingly. By ending the joint table fellowship between Jew and Gentile Christians, it dissolved the glue that held together churches like those in Antioch.

The Second Decree

Something had to be done to avoid schism. The result was a second decision holding Gentiles to the same rules spelled out in Leviticus 17 and 18 for Gentiles who are resident aliens in Israel. Acts 15:20 spells it out:

“We should write to them to abstain only from things polluted by idols and from fornication and from whatever has been strangled and from blood.” (NRSV)

Three of these are clearly dietary regulations: abstinence from (1) meat that was part of a pagan sacrifice (Lev 17:8-9); (2) meat from an animal that was not butchered by having the blood drained from it (17:14-15); and (3) food made from the blood of animals (17:10-12).

The odd man out in this list is porneia in Greek, translated variously as “fornication”, “unlawful marriage” (NABRE), “sexual immorality” (NIV), and “unchastity” (RSV). It is a vague term, so we look to the context to understand it. The other three restrictions come from Lev 17, and Lev 18:6-18 lists a variety of sexual unions among kin that are forbidden. As with the dietary rules, these incestuous unions are not just demanded of Jews, but also of resident aliens (Lev 18:26).

James’ cryptic statement in Acts 15:21 regarding how Moses has been read aloud in the synagogues every Sabbath must be his way of saying that these are not rules that he has invented but are rules that were set forth by Moses for Gentiles living with Jews. Any Gentile familiar with the Torah would also be familiar with the regulations in the Holiness Code. In short, if it was good enough for Moses, it was good enough for James.

Finally, these were rules imposed for a mixed community. If the local church consisted of none but Gentiles, the dietary restrictions would not need to be followed. Gentile Christians in those areas, like Christians today, could still enjoy black pudding or eat their steaks rare.
