For the most part, this debate has been about words to no profit. The details are being debated while one of the most important points has been ignored. In Ephesians 5, the relationship of husband-wife is a picture of Christ and His church. If a man, who is a pastor, is divorced and remarried, what does it say about Christ and the church? Can Christ divorce His church? Furthermore, marriage is a covenant, not a sexual relationship* (RC view). The covenantal relationship here is what’s important. Covenant-keeping, as you well know, is central to the character of God. (Hint: Look at the names of God, etc.) Furthermore, it is a matter of qualification, not sin and forgiveness. It appears that we are arguing about marriage, one-flesh relationship, etc. without having a clue about the Biblical teaching on the same. We are debating common sense and cultural norms which are relative.
*RC teaching is that marriage is consummated by the sex act. Wrong! Joseph and Mary were married[\b] before the birth of Jesus even though the Bible specifically states that Mary “knew not a man” (i.e. did not participate in sexual act) before the birth of Christ. Marriage takes place at the altar, not in bed.
