Thanks for that! Downloaded.

That
s a good piece to meditate on: its a love poem and shows that Truth and Beauty go together.
To repeat something said earlier, St Jerome condemned the claim that Mary had other children, calling it “…a novel, wicked and daring affront to the faith of the whole world.”
Until then, no one (apart from Gnostics etc.) had publicly taught it. It was taken for granted that all members of the Church knew she had only one Child. It was only after that heresy became troublesome that the Church had to formally pronounce the truth.
It
s the same with the "Jesus was married." claim. Its taken for granted that we all know, without the Church
s having to make a formal declaration. [Maybe she has, but im not aware of it.]
There
s a relative new heresy which says Mary doesnt have a biological father. If that gets out of hand, again, the Church would have to pronounce against it.
“Sensus fidei”
In one way, heresy is good because it forces the Church to be more precise with her definitions.
Ephesians 5:
Not proof that Jesus wasn`t married, but it reinforces the reality of the Bridegroom/Bride.
