Is gay marriage allowed in christianity

Today, most denominations teach that homosexual behavior and acts are sinful, [2] and both the Eastern Orthodox Church and the Catholic Church officially condemn homosexual activity as sin.
Same-sex marriage is a distortion of the biblical model and is not honored by God as true marriage. At the same time, God offers forgiveness and grace to all who repent, recognizing that gay marriage is a sin and against God’s good design of sexuality and marriage (2 Corinthians ).
