Satan perverted the law of Moses. So Jesus called him the Jews’ spiritual father, Jn 8.44. He called the Jews who persecuted the church “the synagogue of Satan” Rev 2.9.
Satan has also perverted the church of God. He is behind the denominational divisions and all attempts to separate people from the apostolic truth, 2 Cor 11.12-15.
People who cause and support such divisions are “worldly, devoid of the Spirit” Jude 19. It plays into the devil’s hands to say that denominations are a good thing. It makes him one’s (un)spiritual father.
