Since Mary is Jesus’ mother, it must be concluded that she is also the Mother of God:

There's the source of so many Catholic failures...

[Eucharista]

"There's the source of so many Catholic failures...

Can you logically support your position that the Catholic Church is in error in regarding Mary as Theotokos? The transitive property of equality says that if a=b, then b=c. If a=b and b=c, then a=c. If Jesus is 100% human and 100% God and Mary is the mother of Jesus, she is therefore the mother of God.
