1. Mary is the mother of Jesus (your words)
1. Jesus = God (your words)
3. Therefore, Mary is the Mother of God. (inescapable conclusion)
Thank you for helping demonstrate that Our Lady is the Mother of God.
For God to have a mother, that would mean that God has a beginning. And, that there would be another god or godess before Him. Logically. God has made it clear to us in scripture that He is the only God in heaven. So, God doesn't have a Mother. Jesus is an entity of the Triune Godhead, The Father, Son and Holy Spirit. All three are separate in characteristics, but of the same.
Mary is not part of the Trinity, nor is she the way to salvation. Only Jesus can forgive sins and is the only way into heaven....John 14:6 - Jesus answered, "I am the way and the truth and the life. No one comes to the Father except through me..."
He didn't include Mary... sorry.
