C0 in Latin means “with”
The Blessed Virgin Mary came bearing the child Jesus.
The Blessed Virgin Mary came “with” the Son of God and Son of Man within her womb.
Hope that clarifies your misinformation. BTW, I don’t think you offered sources (Live-Links) for all that.
What I am posting is common Latin language knowledge.
You're correct that I forgot my link, so here it is. Sorry about that.
However, while I agree with what you've posted here, that doesn't begin to cover what the Catholic Church attempts to teach about Mary. Like I said, I have no problem venerating her, just don't worship her as co-redeemer, which is what the RCC seems to be teaching.
