The church leaders counsel Paul to combat words with action. Four pious but indigent men in the congregation have taken on themselves a Nazirite vow of limited duration (Num 6). By abstaining from products of the vine, not cutting their hair and avoiding ritual impurity, they have been showing thankfulness for past blessings, earnestness in petition or strong devotion to God. The multianimal sacrifice and cleansing ceremony at the end of the vow period, when the hair is cut and offered to God, is financially prohibitive (6:13-20). Paul is asked to bear the expenses of the four. This was a commonly recognized act of piety (Josephus Jewish Antiquities 19.294). To do so he must go through a seven-day ritual cleansing himself, because he has recently returned from Gentile lands (m. Oholot 2:3; 17:5; 18:6; Num 19:12). The intended result is that the rumors about Paul will be shown to be baseless and he will be seen living in obedience to the law. Lest Paul's action be misunderstood in another direction, as making Jewish custom normative for Gentile Christians, the elders hasten to add that the Jerusalem Council decree is still in place (see discussion above at Acts 15:20, 29). It is repeated here in essential detail.

The next day Paul begins his own ritual purification and declares to temple authorities the date that the Nazirite vow, here called the days of purification (Num 6:5 LXX), would be completed through a sacrificial ceremony (m. Nazir 6:7).

What does the elders' counsel to Paul say about Luke's view of Christians and their religious past? Before we can draw general principles, we must deal with unique and theologically significant factors concerning the Jewish law. At its core was divine revelation in three aspects: moral, civil and ceremonial. Surrounding that were oral tradition and rabbinic exposition. Luke's use of terminology often prevents us from easily distinguishing which aspects of the law he is referring to. Still, Luke's use of the term customs does seem to show he is aware of the difference between divine revelation and human tradition (15:1; 21:21; 26:3; 28:17). And there may be a distinction in Luke's thinking between the moral, ceremonial and civil aspects which will enable us to make decisions about normativeness based on content (Lk 10:25-28).

If we focus on the divine revelation component of a Jewish Christian's religious past, the Old Testament law, we can see Luke says it has no relevance for salvation (Acts 13:38-39; 15:10-11). While the moral aspect is universally normative (Lk 10:25-28; 18:18-23), Luke also sees a positive use for the ceremonial laws, to aid Jewish Christians in the expression of their piety. He does not make these laws binding on Gentiles, however. Only when Gentiles are in the company of Jewish Christians with scruples should they keep ceremonial ritual purity, and then not beyond what God mandated in the Old Testament for aliens living in Israel.

What guidelines does this incident yield for today? There is a large measure of freedom, but that freedom is to be used to promote (1) the advance of the gospel and (2) the unity of an ethnically diverse church. So long as our conscience is not bound by non-Christian traditions and practices and the Christian gospel is not syncretized with the thought behind non-Christian practice, our pre-Christian religious past, properly cleansed, may move into a transformed spiritual future.
