But he OKs divorce and remarriage...
The point here is that the “remarried” couple are not really married in the eyes of God at all, but are committing adultery. This is not just an opinion. Jesus says this in the Gospels of Mark and Luke and twice in Matthew.
Really??? You can't even find that in YOUR bible with out misquoting the verses or leaving something out or putting something in...
But regardless, here's the clincher...Jesus was speaking to Jews, under the law...We as Christians are not under the law...We are covered by grace..."There is no condemnation for those who are in Christ Jesus"...
It's also clear that he was forbidding what had become a common practice among the Jews: that a man could divorce his wife simply by giving her an official dismissal, a certificate of divorce, which the Pharisee Hillel said was all that was needed. (The Pharisee Shammai was stricter, and said there had to be a serious reason for it.)
This is why His followers were astonished, a found it a "hard saying": in saying they were not to divorce, Jesus went way beyond both Pharisee schools of thought, Hillel and Shammai.
See Matthew 5:32, Matthew 19:9, Mark 10:11, Mark 10:12, Luke 15:18.
He repeats it over and over: no divorce. And if you remarry, it's adultery.
This, then, became the practice of the early Church-- as we see in Corinthians--- and it held even for marriages between Christians and non-Christians:
1 Corinthians 7:11 But even if she does depart, let her remain unmarried or be reconciled to her husband. And a husband is not to divorce his wife.
1 Corinthians 7:12
But to the rest I, not the Lord, say: If any brother has a wife who does not believe, and she is willing to live with him, let him not divorce her.
1 Corinthians 7:13
And a woman who has a husband who does not believe, if he is willing to live with her, let her not divorce him.
