"Didnt He state "I am the Lord, and I do not change"?"
And yet people forget Jesus said:
"And it was said, 'Whoever divorces his wife, let him give her a certificate of dismissal'; but I say to you that everyone who divorces his wife, except for the cause of unchastity, makes her commit adultery; and whoever marries a divorced woman commits adultery." (Matt 5:31-32, NASB)
"And I say to you, whoever divorces his wife, except for immorality, and marries another woman commits adultery." (Matt 19:9)"
