Both Catholics and Orthodox Christians believe that the blessed Virgin Mary remained a virgin not only until she had given birth to the Lord but for her entire life, but most Protestants use Matthew 1:25 as evidence that Mary did have sexual relations with Joseph, but what arguments do Catholics and Orthodox Christians use against Matthew 1:25 disproving the perpetual virginity of Mary?
Matthew 1:25 reads:
And knew her not till she had brought forth her firstborn son: and he called his name Jesus.
I would really like to hear this perspective from Catholic and Orthodox Christians.
