What does God say about the indissolubility of marriage and adultery in the New Testament?

“Anyone who divorces his wife and marries another woman commits adultery, and the man who marries a divorced woman commits adultery”. (Lk 16:18)

“To the married I give this command (not I, but the Lord): A wife must not separate from her husband. But if she does, she must remain unmarried or else be reconciled to her husband. And a husband must not divorce his wife”. (1 Corinthians 7:10-11)

“Or do you not know that wrongdoers will not inherit the kingdom of God? Do not be deceived: Neither the sexually immoral nor idolaters nor adulterers nor men who have sex with men nor thieves nor the greedy nor drunkards nor slanderers nor swindlers will inherit the kingdom of God”. (1 Corinthians 6:9-10)

“The woman said to him: “Sir, give me this water so that I won’t get thirsty and have to keep coming here to draw water”. He told her, Go, call your husband and come back. “I have no husband,” she replied. Jesus said to her, “You are right when you say you have no husband. The fact is, you have had five husbands, and the man you now have is not your husband. What you have just said is quite true.” “Sir,” the woman said, “I can see that you are a prophet”. (Jn 4:15-19)

“Jesus then left that place and went into the region of Judea and across the Jordan. Again crowds of people came to him, and as was his custom, he taught them. Some Pharisees came and tested him by asking, “Is it lawful for a man to divorce his wife?” “What did Moses command you?” he replied. They said, They said, “Moses permitted a man to write a certificate of divorce and send her away”. “It was because your hearts were hard that Moses wrote you this law,” Jesus replied. “But at the beginning of creation God ‘made them male and female.’ ‘For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh.’ So they are no longer two, but one flesh. Therefore what God has joined together, let no one separate.” When they were in the house again, the disciples asked Jesus about this. He answered, “Anyone who divorces his wife and marries another woman commits adultery against her. And if she divorces her husband and marries another man, she commits adultery””. (Mk 10:1-12)

“When Jesus had finished saying these things, he left Galilee and went into the region of Judea to the other side of the Jordan. Large crowds followed him, and he healed them there. Some Pharisees came to him to test him. They asked, “Is it lawful for a man to divorce his wife for any and every reason?” “Haven’t you read,” he replied, “that at the beginning the Creator ‘made them male and female, He answered, and said, ‘For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh.’ So they are no longer two, but one flesh. Therefore what God has joined together, let no one separate”. “Why then,” they asked, “did Moses command that a man give his wife a certificate of divorce and send her away?” Jesus replied, “Moses permitted you to divorce your wives because your hearts were hard. But it was not this way from the beginning. I tell you that anyone who divorces his wife, except for sexual immorality, and marries another woman commits adultery. And the man who marries a divorced woman commits adultery”. (Mt 19:1-9)

“You have heard that it was said, ‘You shall not commit adultery. But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart. If your right eye causes you to stumble, gouge it out and throw it away. It is better for you to lose one part of your body than for your whole body to be thrown into hell. And if your right hand causes you to stumble, cut it off and throw it away. It is better for you to lose one part of your body than for your whole body to go into hell. “It has been said, ‘Anyone who divorces his wife must give her a certificate of divorce. But I tell you that anyone who divorces his wife, except for sexual immorality, makes her the victim of adultery, and anyone who marries a divorced woman commits adultery”. (Mt 5:27-32)

“Submit to one another out of reverence for Christ. Wives, submit yourselves to your own husbands as you do to the Lord. For the husband is the head of the wife as Christ is the head of the church, his body, of which he is the Savior. Now as the church submits to Christ, so also wives should submit to their husbands in everything. Husbands, love your wives, just as Christ loved the church and gave himself up for her to make her holy, cleansing her by the washing with water through the word, and to present her to himself as a radiant church, without stain or wrinkle or any other blemish, but holy and blameless. In this same way, husbands ought to love their wives as their own bodies. He who loves his wife loves himself. After all, no one ever hated their own body, but they feed and care for their body, just as Christ does the church— for we are members of his body. ‘For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh. ’This is a profound mystery—but I am talking about Christ and the church. However, each one of you also must love his wife as he loves himself, and the wife must respect her husband”. (Ephesians 5:21—33)

“But Jesus went to the Mount of Olives. At dawn he appeared again in the temple courts, where all the people gathered around him, and he sat down to teach them. The teachers of the law and the Pharisees brought in a woman caught in adultery. They made her stand before the group and said to Jesus, “Teacher, this woman was caught in the act of adultery. In the Law Moses commanded us to stone such women. Now what do you say?” They were using this question as a trap, in order to have a basis for accusing him. But Jesus bent down and started to write on the ground with his finger. When they kept on questioning him, he straightened up and said to them, “Let any one of you who is without sin be the first to throw a stone at her”. Again he stooped down and wrote on the ground. At this, those who heard began to go away one at a time, the older ones first, until only Jesus was left, with the woman still standing there. Jesus straightened up and asked her, “Woman, where are they? Has no one condemned you?” “No one, sir,” she said. Jesus said to her, “Then neither do I condemn you,” “GO NOW AND LEAVE YOUR LIFE OF SIN.” (Jn 8:1-11)

Jesus saved the adulterous woman, but made a condition – GO NOW AND LEAVE YOUR LIFE OF SIN…

“Marriage should be honored by all, and the marriage bed kept pure, for God will judge the adulterer and all the sexually immoral”. (Hebrews 13:4)

“For John had been saying to Herod, “It is not lawful for you to have your brother’s wife””. (Mk 6:18)

“Now Herod had arrested John and bound him and put him in prison because of Herodias, his brother Philip’s wife, for John had been saying to him: “It is not lawful for you to have her””. (Mt 14:3-4)

“Blessed rather are those who hear the word of God and obey it”. (Lk 11:28)

A footnote to the Gospel of St. Matthew (Biblia Tysiąclecia, Pallottinum) relating to section 5:32 contains the following remark:
It results clearly and unequivocally from all three Synoptics that Jesus restored the original indissolubility of marriage and did not allow any divorce (Mt 19:6-9; Mk 10:2-12; Luke 16:18; compare 1 Corinthians 7:10n). The exception that is mentioned here and in Mt 19:9, should be probably understood as a reference to a marriage that is not valid or legally contracted. However, any sexual relation of two people outside of marriage is always adultery. The Greek term gyne used here means both wife, and woman in general. Only Matthew takes into account the rabbinical discussions”.

(Sixth) Commandment, expressed several time in Scripture reads as follows:
“You shall not commit adultery”. (Exodus 20:14)

“You shall not commit adultery”. (Deuteronomy 5:18)

“If a man commits adultery with another man’s wife—with the wife of his neighbor—both the adulterer and the adulteress are to be put to death”. (Lev 20:10)

“The eye of the adulterer watches for dusk; he thinks, ‘No eye will see me,’ and he keeps his face concealed”. (Job 24:15)

“But a man who commits adultery has no sense; whoever does so destroys himself”. (Prov 6:32)

“(…) disturbance of decent people, forgetfulness of favours, pollution of souls, sins against nature, disorder in marriage, adultery and debauchery”. (Wisdom 14:26)

“and the man who sins against the marriage bed and says to himself, ‘Who can see me? There is darkness all round me, the walls hide me, no one can see me, why should I worry? The Most High will not remember my sins.’ What he fears are human eyes, he does not realise that the eyes of the Lord are ten thousand times brighter than the sun, observing every aspect of human behaviour, seeing into the most secret corners. All things were known to him before they were created, and are still, now that they are finished”. (Sir 23:18)

“I shall pass on you the sentence that adulteresses and murderesses receive; I shall hand you over to their jealous fury;” (Ez 16:38)

“Only perjury and lying, murder, theft, adultery and violence, bloodshed after bloodshed”. (Hosea 4:2)

“I am coming to put you on trial and I shall be a ready witness against sorcerers, adulterers, perjurers, and against those who oppress the wage-earner, the widow and the orphan, and who rob the foreigner of his rights and do not respect me, says Yahweh Sabaoth”. (Malachi 3:5)

For I hate divorce, says Yahweh, God of Israel, and people concealing their cruelty under a cloak, says Yahweh Sabaoth. Have respect for your own life then, and do not break faith”. (Malachi 2:16)

Catechism of the Catholic Church

“What sins are gravely opposed to the sacrament of Matrimony? Adultery and polygamy are opposed to the sacrament of matrimony because they contradict the equal dignity of man and woman and the unity and exclusivity of married love. Other sins include the deliberate refusal of one’s procreative potential which deprives conjugal love of the gift of children and divorce which goes against the indissolubility of marriage”. (Compendium of the Catechism of the Catholic Church 347)

Divorce does injury to the covenant of salvation, of which sacramental marriage is the sign”. (Catechism of the Catholic Church 2384)

Moreover, a footnote to the Gospel of St. Matthew (Biblia Tysiąclecia, Pallottinum) relating to section 5:32 contains the following remark:
