Below is link to a good article on “All Along the Watchtower” (a great site) about the perpetual virginity of the Blessed Virgin Mary. All Along the Watchtower has several contributors (Catholic and non-Catholic). This post is written by Chalcedon451.
Below is a small snippet. Go to All Along the Watchtower as Chalcedon451 discusses the use of the phrase “did not know her til”, and how that does not disprove Mary’s perpetual virginity.
Rob asks how one can reconcile the belief in Our Lady’s perpetual virginity with the passage in Matthew 1:23-24:
Then Joseph, being aroused from sleep, did as the angel of the Lord commanded him and took to him his wife, 25 and did not know her till she had brought forth her firstborn Son.And he called His name Jesus.
So, on the basis that ‘did not know her till’ we are to discount the teaching of the Fathers and the belief of both the Catholic and the Orthodox Churches for as far back as records run; indeed, on the basis of that English phrase, we are to believe that the Church which canonised the Bible and taught the perpetual virginity had never read its own book and noticed the discrepancy?
