Or in another way. By three are signified those who have faith in the Trinity, by two the unbelievers who depart from the unity of the faith. But the father is the devil, whose children we were by following him, but when that heavenly fire came down, it separated us from one another, and shewed us another Father who is in heaven. The mother is the Synagogue, the daughter is the Primitive Church, who had to bear the persecution of that same synagogue, from whom she derived her birth, and whom she did herself in the truth of the faith contradict. The mother in law is the Synagogue, the daughter in law the Gentile Church, for Christ the husband of the Church is the son of the Synagogue, according to the flesh. The Synagogue then was divided both against its daughter in law, and its daughter, persecuting believers of each people. But they also were divided against their mother in law and mother, because they wished to abolish the circumcision of the flesh.
