One of the many false doctrines of the Roman Catholic Church is that Mary remained a virgin even after the birth or Christ. Where does this teaching come from and is there any merit to it at all?
The doctrine of Mary’s perpetual virginity first shows up in the early fourth century. It is curious that such a distinction would not be made prior to this. This is especially perplexing because the New Testament clearly refers to Jesus having siblings.
Now I want to make a distinction, we are not denying the virgin birth of Christ. That is clearly Scriptural (Luke 1:34). The birth of Christ was a miraculous event. What is in question here is the idea that Mary continued to be a virgin the rest of her life. So let’s look at the evidence.
The first piece of evidence is the telling of Joseph’s perspective in Matthew chapter one. It tells us in verse 25 that Joseph did not know Mary, meaning sexual intimacy, until after the birth of Christ. There would be no reason to make this statement if Mary were a perpetual virgin.
The second piece of evidence is, as stated earlier, the Bible states that Jesus had siblings (Matt. 13:55; Mark3:31, 33; John 2:12; 7:3, 5, 10; Acts 1:14; 1 Cor. 9:5; Gal. 1:19). The Catholic Church would state that these would not be blood brothers, they would be cousins or close friends, but there is nothing within the context of the text to actually suggest this explanation.
In short, there is no evidence to suggest, and no reason to believe, that Mary remained a virgin after the birth of Christ. The evidence is to the contrary. This is another way in which the Roman Catholic Church turns Mary into a sort of god and an idol as they do with declaring that she was sinless her entire life.
