Against the Audaeans. The same Audaeans mention the Constitu- tion of the Apostles .... about the Passover .... for the Apostles define in that Constitution that ye reckon not, but observe [it] when your brethren from the circumcision do ; do so together with them ; and they did not say, " when your brethren in the circumcision," but " those from the circumcision," that they might show that those who had come over into the church from the circumcision were leaders after that time ; with Apostles this is enjoined for the sake of harmony, as they testify, saying that even if they err it is no matter to you .... they say to keep vigil in the midst of the feast of unleavened bread. See p. 97, 1. 33.
