God is our Father (Matthew 6:9; cf. John 1:12-13); Jesus is the Son of God; Mary is Jesus’ mother; therefore, Mary is our Mother. Also: “For whoever does the will of my Father in heaven is my brother and sister and mother.” (Matthew 12:50)
“God is our Father (Matthew 6:9; cf. John 1:12-13); Jesus is the Son of God; Mary is Jesus mother; therefore, Mary is our Mother.”
This doesn’t pass any logic test at all.
