Besides the fact that the Church has taught that Mary was always a virgin from its earliest days before the New Testament was even written, it continues to do so today because of what this fact says about Jesus. From the cross Jesus shared his Mother with us all. But her womb was a tabernacle for him alone. We wouldn’t think of using the tabernacles in our churches to house anything but the Eucharist because it is the sacred body of Christ; so too with Mary’s womb. It’s all about who Jesus is. Mary is special because of how much more he is special. She is all about him!
