Patrick explains that the Bible does not argue against Mary's perpetual virginity, but rather is silent on the issue, neither confirming nor denying that she had children other than Jesus. He points to several pieces of evidence, such as only Jesus ever being referred to as the son of Mary, Jesus entrusting Mary to the care of Saint John rather than a sibling, and some of the "brothers of Jesus" mentioned being sons of a different Mary. Patrick believes there is ample biblical evidence refuting the idea that Mary had other children besides Jesus.
