If the teaching on the perpetual virginity of Mary contradicts Scripture, the teaching must be wrong and I will apologize. However, Scripture supports it.
In the case of Mary’s perpetual virginity, Matthew 13:55 uses the Greek word for "brethren" (adelphoi) and its feminine counterpart (adelphe). If the Greek words used in this passage connote only siblings, then the Catholic dogma of Mary’s perpetual virginity is false.
However, the word adelphoi has a much broader meaning. It may refer to male relatives that one is not a descendant of and that are not descendant from one (such as a blood brother, step-brother, nephew, uncle, cousin, etc.) or non-relatives such as neighbors, fellow workers, co-religionists, and friends.
Because of this broad usage, we can be sure that the 120 "brothers" in Acts 1:15 did not have the same mother. Neither did Lot and his uncle Abraham, who were called "brothers" (Gen. 11:26-28, 29:15).
The reason relatives were called brothers or sisters was because in Hebrew, there was no word for cousin, nephew, or uncle. So the person was referred to as simply a "brother." Linguistically, this was far easier than calling the person the son of a mother’s sister. Since the New Testament was written in a dialect of Greek that was heavily influenced by the Semitic culture, many of the Hebrew idioms (like "brother" having multiple meanings) intrude into the Greek text. So, the fact that Jesus had adelphoi does not mean that Mary had other children.
