Catholicism does. They call Mary *the mother of God*.
“Catholicism does.”
That’s a complete falsehood - the Catholic Church does not EVER say that Mary is the mother of the Father or the Holy Spirit. The fact that what you said is completely untrue most likely will not stop you from saying it again.
“They call Mary *the mother of God*.”
Because the Incarnate Word is God. Jesus is God. Mary carried and gave birth to Him. He is the Lord - just at the Holy Spirit points out through St. Elizabeth in Luke 1:43.
Could that be because Jesus and God are one in the same?
