What did Jesus say, if anything, about gay marriage? A lot, and to the point, says Daniel Akin, president of Southeastern Baptist Theological Seminary in Wake Forest, N.C.
He gives His perspective on this when He addresses the issue in Matthew 19:4-6. There, speaking to the institution of marriage, Jesus is clear when He says, “Have you not read that He who created them from the beginning made them male and female, and said, ‘Therefore a man shall leave his father and his mother and hold fast to his wife, and the two shall become one flesh’? So they are no longer two but one flesh. What therefore God has joined together, let not man separate.”
That Jesus was committed to heterosexual marriage could not be more evident. A man is to leave his parents and be joined to a woman who becomes his wife. This is heterosexual marriage.
In case you were wondering. Akin has more on the point, including this:
We must not isolate Jesus from His affirmation of the Old Testament as the Word of God nor divorce Him from His first century Jewish context.
Read him in context to understand what he meant, that is, not to debunk it by making him simply a creature of his time. Word to the wisdom, this.
