I imagine many people "touched" Mary, just not the way we were talking in this thread. I think you are stretching things a wee bit here.
She was cleansed of original sin before her birth
I always wondered why she acknowledged needing a Savior in Luke 1:47. Also, what happened to "all have sinned and fall short of the glory of God" (Ro. 3:23).
I know I am not going to convince you, and neither are you likely to change my mind. Honestly, what difference does it make to our salvation whether Mary remained a virgin or not? The important thing is that she was a virgin when she conceived and so she delivered the perfect, spotless Lamb of God.
It's too late for me, so good night, peace and grace to you.
Mary's virginity makes no difference to our salvation but it has a huge impact on church doctrine.
I was raised Catholic but married in an evangelical Christian church and didn't want to put my new bride through the burden of becoming Catholic. It took only a couple months of adult Bible study to convince me that I could never subscribe to Catholic doctrine again.
There is no evidence in the Bible that Mary was a perpetual virgin. There is lots of circumstantial evidence that she could not have remained a virgin after Jesus birth. To wit:
* There are two Biblical passages which clearly note that Joseph did not know his wife until she gave birth to the child by the Holy Spirit.
* Jesus was raised as a carpenter under the tutelage of his father. It's hard to imagine that, after the Savior's birth, Joseph would not have engaged in normal martial relations with his wife. Joseph did not vanish after Jesus' birth.
* There are multiple NT passages that refer to Jesus' brothers, in particular, James, who did not believe his brother was the Messiah until after his brother's resurrection. At least 10 passages.
But the real issue I had with Catholic doctrine is when the church calls Mary the "co-redemtrix," meaning that we Christians can be redeemed EITHER through Jesus or his mother. There is zero Biblical basis for this Catholic doctine. The first time I read that passage in John 14:6, "No one comes to the Father except through me," all the scales over my eyes fell away.
So why did the Catholic church of old insist that Mary was a perpetual virgin? Probably because a perpetual virgin -- with those notions of forever being clean -- was the only way to justify her role as an equal path to salvation as Jesus himself.
Sorry, Catholics, I'm not intending to create discord here, but it does matter whether Mary was a virgin. The only path to salvation is through Christ, not his mother. She was neither a perpetual virgin, nor a path to salvation.
