“Jesus is the Redeemer; Mary is Co-Redemptress
??? Who is this idiot spouting this nonsense? “
This is indeed Catholic doctrine, and I most cetainly believe it.
If Mary had not accepted to be the Mother Of Jesus, who is God, and Spouse of the Holy Spirit, who is God, then no redemption of humanity would be possible!
God gave every human being free will, and He never, ever overrides it, even in the case of Mary, who was without sin.
Having said this, I don’t want to get into a theological debate, since I am unqualified
There is no redeemer except Jesus Christ. Catholic doctrine has high regard for Mary and her role in bringing our Lord into the world but does not teach of a co-redeemer.
