ancient heretics who pretended that the Holy Virgin did not preserve a perpetual virginity, but that she had several children by Joseph after our Saviour's birth. Their opinion was grounded on some expressions of our Saviour, wherein he mentions his brothers and his sisters; and of St Matthew, where he says, that Joseph knew not Mary till she had brought forth her first-born son. The Antidicomarianites were the disciples of Helvidius and Jovinian, who appeared in Rome toward the close of the fourth century.
