a.k.a. The Apostolic Conference
The Council of Jerusalem (led by Paul) exempts Christians from the precepts of Jewish law.
Inasmuch as the Greek Paulines Christians radically undermine—and indeed, overthrow—the Orthodox Judaism of Jesus, and his successor James the Just, the true details and even the date of the Council of Jerusalem are shrouded in political positioning. The Church would like to date the Council of Jerusalem as early as possible (to 50 CE), and portray James as yielding somewhat on Jewish law as regards a class of converts.
This author believes that James the Just never yielded on halachah—Jewish law—and that the Council of Jerusalem may have taken place closer to his murder c. 62 CE. Indeed, in my opinion, it was probably James’s stalwart defense of the Orthodox Judaism of his crucified brother, which resulted in his possibly politically–inspired lynch–murder.
