It doesn't. So if I were a sola scriptura Protestant, I really wouldn't be able to comment on the matter of Mary's perpetual virginity, one way or the other.
But I am comfortable with Joseph not wanting to have sex with her too..it makes no difference either way Jesus is the Son of God, born by a Virgin Birth ..planned before the foundation of the earth to pay for my sins..He died on the cross and rose from the dead ..He is my Savior and my Lord and my King whether his mom had sex or not..
If it weren't for Catholics that are duped by tradition that contradicts Scripture there would be no need for the foolish discussion on Mary's virginity.
Why is that papists want us to defend our views with scripture and then hide behind the skirt of tradition and sola scriptura when the same thing is asked of them?
Hypocrisy or scriptural ignorance?
