Then there is what Christ called it - adultery - and adultery is adultery no matter how you spin it. The divorce is a divorce (single act) and adultery is adultery - ongoing rather than a single act if remarried.
Mark. 10.11 And he saith unto them, Whosoever shall put away his wife, and marry another, committeth adultery against her. 12 And if a woman shall put away her husband, and be married to another, she committeth adultery .
Matt. 5.32 But I say unto you, That whosoever shall put away his wife, saving for the cause of fornication, causeth her to commit adultery : and whosoever shall marry her that is divorced committeth adultery .
Matt. 9.9 And I say unto you, Whosoever shall put away his wife, except [it be] for fornication, and shall marry another, committeth adultery: and whoso marrieth her which is put away doth commit adultery. 10 His disciples say unto him, If the case of the man be so with [his] wife, it is not good to marry .
Note the disciples reaction - seems they caught the drift of what He was saying.
