Jesus said “What God has joined, let no man separate.” So far, in theory, the only church I’ve heard of which has taken a hard line on this teaching is the Roman Catholic Church. Except they have a little weasel clause: Annulment. The Church does not separate what God has joined… it only declares that it never was joined in the first place.
Fair enough. I will recognize the church’s authority here when it has proven it by annulling some other act of God. An earthquake, perhaps, or a hurricane.
