To all:
After looking at the verses on this again, I am convinced that remarriage is only allowed if the previous spouse is dead. Remarriage (while the other ex spouse is alive) according to Jesus and Paul is forbidden.
Divorce & remarriage according to Jesus:
“Furthermore it has been said, ‘Whoever divorces his wife, let him give her a certificate of divorce.’ But I say to you that whoever divorces his wife for any reason except sexual immorality causes her to commit adultery; and whoever marries a woman who is divorced commits adultery.”
(Matthew 5:31-32).
“The Pharisees also came to Him, testing Him, and saying to Him, ‘Is it lawful for a man to divorce his wife for just any reason?’
And He answered and said to them, ‘Have you not read that He who made them at the beginning “made them male and female,” and said, “For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh”? So then, they are no longer two but one flesh. Therefore what God has joined together, let not man separate.’
They said to Him, ‘Why then did Moses command to give a certificate of divorce, and to put her away?’
He said to them, ‘Moses, because of the hardness of your hearts, permitted you to divorce your wives, but from the beginning it was not so. And I say to you, whoever divorces his wife, except for sexual immorality, and marries another, commits adultery; and whoever marries her who is divorced commits adultery.’
His disciples said to Him, ‘If such is the case of the man with his wife, it is better not to marry.’
But He said to them, ‘All cannot accept this saying, but only those to whom it has been given …’” (Matthew 19:3-11).
“Whoever divorces his wife and marries another commits adultery; and whoever marries her who is divorced from her husband commits adultery.” (Luke 16:18).
Divorce and remarriage according to Paul:
“Or do you not know, brethren (for I speak to those who know the law), that the law has dominion over a man as long as he lives? For the woman who has a husband is bound by the law to her husband as long as he lives. But if the husband dies, she is released from the law of her husband. So then if, while her husband lives, she marries another man, she will be called an adulteress; but if her husband dies, she is free from that law, so that she is no adulteress, though she has married another man.” (Romans 7:1-3).
“Now to the married I command, yet not I but the Lord: A wife is not to depart from her husband. 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 7:10-11).
Following Jesus is not always easy.
Remember the disciples who could not bear Jesus' teachings and they walked no more with Him? (See: John 6:66).
