1 Corinthians 6:19
>What? know ye not that your body is the temple of the Holy Ghost [which is] in you, which ye have of God, and ye are not your own?
Mutilating your genitals to feed into your mental illness is a clear offense against God
Now don't think I'm ridiculing transgenders but strictly speaking a transwoman is a mentally ill man. That can't be changed. A "marriage" between a normal man and a transwoman goes against God's design of marriage which is between a man and a woman in Christian faith.
Genesis 2:24
>Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh.
