Why do Christians disagree on gay marriage?

“From the Old Testament and throughout the New Testament, the only sexual relationships that are affirmed in scripture are those in the context of marriage between one man and one woman,” she says.

Actually, the Old Testament does condone polygamy. Still, LaBerge says, from Leviticus to Paul’s writings in Romans and First Corinthians, homosexual acts are called vile and detestable, and legalizing same-sex relationships does not change the sin.

Not so fast, says Rev. Susan Russell, an Episcopal priest at All Saints Church in Pasadena, Calif. She takes her cues from Jesus.

“Jesus never said a single word about anything even remotely connected to homosexuality,” she says.
