Second marriage with first living spouse is adultery...

If a man divorces his first wife, he is not free to marry another woman unless his wife has died.

The Bible says and nothing can sanctify or make legal a "marriage" to a second wife, not the passage of time, not the conversion of one or both partners, not custom, not human law, not public or popular opinion. , nor the decree or "blessing" of the church can make lawful a second "marriage" while the first spouse still lives."

This is what the Bible says...

""Repent" and continue to live in the same adulterous and sinful relationship with a second or third "wife" is not repentance.

This the Bible also seems to teach.

If Jesus judges a relationship as adultery, then repent means that the adulterous relationship must cease. Continuing, claiming love, or any other reason, does not change the fact that it is adultery.

A BIBLICAL TRUTH that few Christians accept!

“Nevertheless, I command those who are married, not I, but the Lord, that the woman does not separate from her husband. If, however, she separates, let her remain unmarried, or let her be reconciled with her husband; and that the husband should not leave his wife (...). But if the unbeliever wants to depart, let him depart; in such (irreconcilable) cases, neither the brother (disputed) nor the sister (disputed) is subject to servitude; God has called you to peace.” 1st Corinthians 7:10,11,15

Paul's focus in 1 Corinthians 7 is the relationship between a man and a woman. The entire chapter is made up of a series of commandments and advice aimed at three different groups: (1) single or widowed people, (2) married people, and (3) believers who married unbelievers. The apostle talks about celibacy, marriage and believers who had married pagans. Now let's undo Satan's and false teachers' deception regarding divorce and remarriage.

Paul forbids divorce and does so on the basis that Jesus forbade it (Mark 10:9; Luke 16:18; Matt. 19:3-9). This is not the mere opinion of the apostle, but the direct revelation of Jesus Christ to him, since no apostle wrote under any influence other than that of the Holy Spirit. Paul says, "not I, but the Lord, command the married", in order to assure the Corinthian believers that Jesus had already taught all this in the Gospels, and that therefore he was not saying anything new there. In contemplating the possibility of a forced breakup, Paul expressly forbids remarriage. It may seem a severe doctrine for relativistic and pagan “Christians” of our era, but the fact is that in Corinth there was an unusual spiritual laxity, a characteristic that marked that church as being the most resistant to Christian discipline due to the customs of its ancient times. beliefs in pagan gods. Nothing belonging to this life was to occupy the attention of the Corinthian believers, and Paul did not give a damn about the sheep of that congregation. This explains why Paul's language is so stern in addressing a class of recent converts who once practiced orgies in devotion to all manner of gods in ancient Greece. Therefore, it was necessary that any kind of impure thinking be avoided among the Corinthians, especially in the sexual area. And Paulo didn't spare the belt. No divorce! Second marriage, except in case of widowhood, also not!

The four immutable rules for married couples in the Church of God prescribed in 1 Corinthians 7 are:

1. Don't separate from your spouse.

2. If you separate (forced separation), stay unmarried.

3. Or, reconcile with her husband.

4. Let the husband not leave his wife.

If there is betrayal within the marriage, forgiveness and prayer for the spouse to be transformed into a new creature in Christ is the correct option.

The only exception for new marriages is for widows, at the end of the letter:

“A married woman is bound by law as long as her husband lives; but if her husband dies, she is free to marry whomever she wants, as long as she is in the Lord.” 1st Corinthians 7.39

Whatever the justifications of divorce and “remarriage” advocates, no passage of Scripture can teach the contrary of what is emphatically commanded in 1 Corinthians 7:39. This passage is the logical conclusion of a whole backdrop that we have seen so far. All of Christ's teaching about marital relationship, separation or union with third parties is concluded here. A new marriage is only allowed in the event of death (physical death; grave).

In 1 Corinthians 7, Paul is aware that a possible forced separation is inevitable. When he writes to the Corinthians on the subject, he is considering in his mind the possibility of unrepentant adultery and such cases as desertion and domestic violence. In order to make it clear to the reader that divorce and remarriage of the divorced are both condemned by God, he addresses spouses who have suffered forced separation and warns them on the basis of the same words as the historical Jesus. These individuals abandoned in marriage must remain celibate, for God has called them to peace and they are not bound to force anyone to maintain ties with them.

Therefore, Luke 16:18, Mark 10:11-12 and Matthew 19:3-11 are the norms that the apostle Paul has in mind when he goes to deal with the Church of Christ in the dispensation of grace. It is for this reason that he says: "... I command the married, not I, but the Lord", alluding to what Jesus had already said in the Gospels, but which needed to be emphasized for a people difficult to understand.

“WHOEVER DIVORCES HIS WIFE AND MARRIES ANOTHER IS IN ADULTERY, and the man who marries a divorced woman is also in adultery.” Luke 16:18

“Nevertheless, to those who are married, I command, NOT I, BUT THE LORD, that the woman must not separate from her husband.

If, however, she separates, that she STAYS WITHOUT MARRYING or that she reconciles with her husband; and let the husband not leave his wife.” 1st Corinthians 7:10-11

“A married woman is bound by law as long as her husband lives; but if her husband dies, she is free to marry whomever she wants, as long as it is in the Lord.” 1st Corinthians 7:39

“Therefore, as long as her husband lives, if she becomes another man's wife, she will be called an adulteress. However, when her husband dies, she is released from the law, so that, without becoming an adulteress, she can marry another man.” Romans 7:3

Did you understand?

“Therefore, if she MARRIES ANOTHER MAN WHILE HER HUSBAND IS STILL ALIVE, she will be considered an adulteress. But if her husband dies, she will be free from that law, and even if she were to marry another man, she would not be an adulteress.” (Romans 7:3)... THUS SAITH THE LORD!...

DO NOT MARRY before consulting the Scriptures: marriage is indissoluble until death (Rom 7:3), it is not for everyone (Mat 19:10,11), “God hates divorce” (Mal 2:16), vow ñ breaks (Eccles 5:4), if you do not forgive, you will not be forgiven (Mat 6:15), etc...

GOD'S ALERT WILL SAVE TRIBULATION AND MANY DIFFICULTIES IN LIFE, "because not everyone is able to accept such responsibility, BUT ONLY THE VOCATIONAL" (Mat 19:10,11)... character to assume the IRREVERSIBLE (Luke 16: 18), with adjustments, resignations, forgiveness, vocation to be a father or mother, husband or wife, for the rest of their lives, it will not be for someone moved by emotions, passions, intention to “legally prostitute themselves”, etc. ... entering the sacred without due reverence and fear is quite dangerous...

Getting married is not the only option for a full life and IT IS NOT FOR EVERYONE (Mat 19:11)... "taking the garbage under the rug", to deliver "zero km"... and the result is a society infested with the divorce that God hates (Mal 2:16), a multitude of abandoned children, split in half, without the his family (a heinous crime)... MARRIAGE IS NO BACK! (Mar 6:17-19)...

“MARRIAGE IS FOR VOCATIONS!” (Mat 19:10,11)... and not for the irresponsible person who does not pay attention to THE GREATER LAW, considers what is sacred banal, marries “in his own fashion”, as in the times of the Flood when “a chosen few” were left ( Mat 24:37-39) and he has to endure until the end the holy commitment whether he wants it or not (Rom 7:3)... IT IS WHAT IS WRITTEN, in the Law that will judge us on the LAST DAY (John 12:47,48 )... “so that what is called for does well, but what is not home does better!” (1st Cor 7:38)...

MARRYING IS NOT FOR EVERYONE (Mat 19:10-11), there is no turning back, but in extreme cases (eg betrayal, aggression) God allows separation, NOT DIVORCE: they are left alone, without remarrying (1st Cor 7:11) until such a one turns from his evil ways or dies (Rom 7:3)...
