Re Perpetual Virginity:
There are a number of Biblical passages that can be used to defend Mary’s perpetual virginity. Keep these two points in mind: (1) the so-called “brothers of Jesus” are never called “sons of Mary” and (2) some of these “brothers” advise and reprimand Jesus. See Jn. 7:3-4 and Mk. 3:21. In Jewish culture, younger brothers never admonished an elder brother. Therefore, they could not have been younger children of Mary.
In Mt. 15:1-6, Jesus vehemently condemns the Pharisees because they had a procedure, the “Korban” rule, that allowed children to avoid taking care of their parents. In the Old Testament, children had a solemn obligation to care for their elderly parents. This is why the Pharisees’ scheme to let people shirk this responsibility made Jesus so angry. With this in mind, look to Jn. 19:26-27 and the scene at the Cross. Jesus is about to die. Apparently, Joseph had already died because he is not mentioned in the Bible after Jesus began His public ministry. Mary is in danger of being left alone, so He entrusts her to John the Apostle, Zebedee’s son, who was NOT a sibling of Jesus. Jesus told John, “Behold your Mother.” If Jesus had had younger siblings, as many Protestants claim, His behavior makes no sense. Jesus had condemned the Pharisees for dispensing people from the responsibility of caring for their parents. Why, if He had them, would He dispense His own siblings from this important obligation? Such inconsistency and hypocrisy on the part of Jesus is inconceivable.
From Acts 1:13-14 we learn that “when they entered the city, they went to the upper room where they were staying, Peter and John and James and Andrew, Phillip and Thomas, Bartholomew and Matthew, James, the son of Alphaeus, Simon the zealot, and Judas, son of James. All these devoted themselves with one accord to prayer, together with some women, and Mary, the Mother of Jesus, and His brothers.”
After the Ascension the followers of Jesus, including Mary, John the Apostle, with whom Mary now lived, and the brothers of Jesus - gathered in the upper room. If these brothers of Jesus were also the sons of Mary, Mary would be praying together with her sons, who were faithful followers of Jesus and yet, going home with John. In her Jewish culture such a situation simply would not happen.
