Pastor Larry, I have enjoyed reading your posts and especially enjoy the boldness in your statements. I do, however, respectfully disagree. I think Scripture is crystal clear on this issue. I further think that many cases of adultery are ignorantly being "joined" together because of a false view of remarriage.
First, the "except" phrase in the Mt 5 passage speaks of divorce. When Jesus mentioned remarriage, He called it adultery. You find the same construct in Mt 19. I think audience is a major role in interpretation. Jesus is preaching to Jews and the context is Jesus correcting the pharisaical interpretation of the law (you have heard it said...). Mark 10 and Luke 16 do NOT record the exception clause. That is huge. They were writing to gentiles. In fact, in Mark and Luke, the statement is absolute. If you divorce and remarry, you have committed adultery.
The "bound" passage you mentioned is undoubtedly 1 Cor. 7:15. Again, this says nothing of remarriage. Paul doesn't teach on remarriage until the end of the chapter (38-40?). In verses 10 and 11, Paul says that if separation must happen, one is left with two options: first, be reconciled; second, remain single. The "bound" in verse 15 is a word that communicates slavery. This is not marriage. When an unbeliever leaves, the believer is not enslaved to try and keep them from leaving. He/she is to let them go and live in peace. Paul uses a different greek word at the end of the chapter to communicate marriage.
If one examines Paul's point in Romans 7:2-3, 1 Cor. 7:38-40, Luke 16:18, Mark 10, Matt 5, and Matt 19, giving equal weight to each passage, the result will be that remarriage except in the case of death is adultery.
