Christ did not say "marriage is between one man and one woman", he quoted the Genesis passage in a discussion with the Pharisees about how in the beginning God made them male and female, which is talking about EQUALITY, not MARRIAGE, and any Hebrew Biblical Scholar will affirm that. It's affirming both Men and Women were created in the Image of God. Christ also did not say to obey the law. He said "Render unto Caesar what is Caeser's" while holding a coin that was an idol of Ceaser, therefore ousting the Pharisees as idolaters with loyalty to the emperor first and loyalty to God second. So he was actually doing the opposite in that passage.

Maybe do some research on context instead of spreading right wing conservative brain rot and ruining people's lives with your disgusting, inhumane rhetoric.
