RE: I have never heard of a Protestant that questioned the Virgin Birth.
Those Protestant who believe the Bible have never questioned the Virgin Birth.
What they question is the IMMACULATE CONCEPTION ( Mary herself conceived without original sin ).
In any denomination, you can find looney toons who question the most basic facts of Christianity. The Episcopal Church famously had Bishop Spong, but there are nuts attending any kind of congregation.
These people are no more believing “Protestants” than they are believing “Catholics.” They are simply non-believers in Christianity.
so you think that God would send His begotten son to reside in a less than perfect environment????Why???
And why is is so important to some that she be declared without original sin. God did what He did to save His children from Hell. He made David pure and sn free before David's death despite some of the things David did - no question that He may have done similar to Mary, but what is the fuss about? No matter her condition, Mary gave birth to the Savior and we were given ready access to His Grace.
