What does the bible say about gay marriage

Jesus addresses and defines marriage in Matthew –6 and Mark –9 using both Genesis –27 and Genesis to parse it out. Here Jesus defines and affirms marriage as between a man and a woman, a reflection of the fact that God made us male and female to care for creation together. With this definition, same-sex marriage is excluded.
The Bible says nothing about gay marriage directly, but it does set down the foundational principles of what constitutes marriage in God’s eyes. Every reference to marriage in the Bible indicates a union of male and female.
