And he saith unto them,
Whosoever shall put away his wife, and marry another,
committeth adultery against her.
Mark 10:11

One day as I was studying "unity", a verse was shown unto me that illuminated my understanding of the phrase that Jesus made when He said "commiteth adultery against her" in Mark 10:11. I was reading Ephesians 1:10

that in the dispensation of the fulness of times
he might gather together in one all things in Christ,
both which are in heaven, and which are on earth; even in him.
Ephesians 1:10

This phrase "he might gather together in one" comes from the Greek word "anakephalaiomai" which is translated only one other place as "briefly comprehended" in Romans 13:9.

Owe no man any thing, but to love one another:
for he that loveth another hath fulfilled the law.
For this, Thou shalt not commit adultery,
Thou shalt not kill, Thou shalt not steal,
Thou shalt not bear false witness,
Thou shalt not covet;
and if there be any other commandment,
it is briefly comprehended in this saying,
namely, Thou shalt love thy neighbor as thyself.
Love worketh no ill to his neighbor:
therefore love is the fulfilling of the law.
Romans 13:8-10

Therefore, the heinous sin of remarriage in most cases is that the spouse that leaves the marriage is not loving the spouse of his/her covenant, but is rather "working ill to his neighbor". In Moses and the Prophets, this is called "dealing treacherously" (from the Hebrew word "bagad") as in Malachi 2:14:

Yet ye say, Wherefore? Because the LORD hath been witness between thee and the wife of thy youth, against whom thou hast dealt treacherously: yet [is] she thy companion, and the wife of thy covenant. And did not he make one? Yet had he the residue of the spirit. And wherefore one? That he might seek a godly seed. Therefore take heed to your spirit, and let none deal treacherously against the wife of his youth.
Malachi 2:13-14

This Hebrew word "bagad" is translated in Exodus 21:8 as "dealt deceitfully" and in Psalm 78:57 as "dealt unfaithfully". In Jeremiah "bagad" is used four times in Jeremiah 3:8, 3:10 and twice in 3:20.

Surely [as] a wife treacherously departeth from her husband, so have ye dealt treacherously with me, O house of Israel, saith the LORD.
Jeremiah 3:20

When a wife puts away her husband then remarries, not only does she commit adultery, but also she "works ill" to her first husband (Romans 13:10); she becomes as "rottenness in his bones" (Proverbs 12:4). In the case of a husband that puts away his wife, Jesus says he "committeth adultery against her". He sins against her, and the wife that leaves sins against him. But they are sinning against their own flesh. As it is written:

Flee fornication. Every sin that a man doeth is without the body;
but he that committeth fornication sinneth against his own body.
1 Corinthians 6:19

So ought men to love their wives as their own bodies. He that loveth his wife loveth himself. For no man ever yet hated his own flesh; but nourisheth and cherisheth it, even as the Lord the church:
Ephesians 5:28-29

When it comes to a husband and a wife, the wife is considered his own flesh. Therefore, the husband that puts away his wife and remarries, sins against his own flesh. Likewise, the wife that puts away her husband sins against her own flesh. Even the wife that has been put away, if she remarries, she sins against her own flesh.

If we are going to ask the question "what are we do with couples that are already remarried (and in most cases in an adulterous situation)?", we must also consider the question "If continuing in adultery is dealing treacherously with my spouse, how are we going to stop dealing treacherously?" If husbands are commanded to love their wives as Christ loved the church, we can have an idea of the LORD's mercy to Israel from Jeremiah and Hosea:

Return, ye backsliding children, [and] I will heal your backslidings.
Jeremiah 3:22

Then said the LORD unto me, Go yet, love a woman beloved of her friend, yet an adulteress, according to the love of the LORD toward the children of Israel, who look to other gods, and love flagons of wine.
Hosea 3:1

But and if she depart, let her remain unmarried, or be reconciled to [her] husband: and let not the husband put away [his] wife.
1 Corinthians 7:11
