So, Catholic religious reasoning goes thus....
Mary is the mother of Jesus, and Jesus is God, therefore, Mary is the mother of God.
Continued is, God is three persons, the Father, the Son, and the Holy Spirit.
If Mary is mother of God, and mother of God the Son, then Mary is mother of God the Father, and God, the Holy Spirit as well.
Or are you denying that the Father and the Holy Spirit are God?
Then how can Mary be the *faithful spouse of the Holy Spirit*, if shes his mom?
Heck; she is the mother of EVERYONE!!!
