Jesus CORRECTED doctrine or rules given in the O.T.
You've chosen a good example...
DIVORCE.
Matthew 5:31-32
31“It was said, ‘WHOEVER SENDS HIS WIFE AWAY, LET HIM GIVE HER A CERTIFICATE OF DIVORCE’;
32but I say to you that everyone who divorces his wife, except for the reason of unchastity, makes her commit adultery; and whoever marries a divorced woman commits adultery.
You must surely know that when Jesus said
"you have heard it said"....
"BUT I SAY TO YOU"......
He is about to correct something that was
CORRECT then
CORRUPTED and
JESUS IS GOING TO CORRECT THE DOCTRINE.
As to Divorce:
God created Adam and Eve.
This was the first marriage.
Genesis says that woman is "flesh of my flesh and bone of my bone" to the Ah-dam.
They were meant to stay together forever.
Genesis 2:24-25 For this cause the man SHALL LEAVE his father and mother and cleave to his WIFE and they shall become ONE FLESH.
We also read....
MARK 10:9
What God has joined together, let no man separate.
Now, as you've stated...did GOD CHANGE HIS MIND?
Why did Moses allow men to divorce their wives if this was originally prohibited by GOD?
Because Moses made the new rule,
NOT GOT.
This is true for other laws in the Torah..they are clearly created by man.
This is NOT raising a standard...
it's RETURNING A STANDARD to its original form before MAN changed what GOD SAID.
Still no reply on Mathew 5:20
How could our righteousness surpass that of the scribes and Pharisees if they followed the same law YOU are following?
