Some passages from the Bible that can help us understand this message.
Gn 1,26-31
And God said: "Let us make man in our image, in our likeness, and dominate the fish of the sea and the birds of the sky, the cattle, all the wild beasts and all the reptiles that crawl on the earth". God created man in his image; in the image of God he created it; male and female created them. God blessed them and said to them: “Be fruitful and multiply, fill the earth; subjugate it and dominate the fish of the sea and the birds of the sky and every living thing that crawls on the earth ”. And God said: “Behold, I give you every herb that produces seed and that is on all the earth and every tree in which it is the fruit, that produces seed: they will be your food. To all the wild beasts, to all the birds of the sky and to all the beings that crawl on the earth and in which it is the breath of life, I feed every green grass ”. And so it happened. God saw what he had done, and behold, it was a very good thing. And it was evening and it was morning: sixth day.
Isaiah 55,12-13
So you will leave with joy, you will be led in peace. The mountains and hills ahead of you will erupt in shouts of joy and all the trees in the fields will clap their hands. Instead of thorns, cypress trees will grow, instead of nettles, myrtle trees will grow; this will be to the glory of the Lord, an eternal sign that will not disappear.
Proverbs 24,23-29
These too are words of the wise. Having personal preferences in court is not good. If one says to the example: "You are innocent", the peoples will curse him, the people will execute him, while everything will be fine for those who do justice, the blessing will pour on them. The one who answers with straight words gives a kiss on the lips. Arrange your business outside and do the field work and then build your house. Don't testify lightly against your neighbor and don't fool with your lips. Do not say: "As he did to me, so I will do to him, I will make everyone as they deserve".
Mt 19,1-12
After these speeches, Jesus left Galilee and went to the territory of Judea, beyond the Jordan. And a large crowd followed him and there he healed the sick. Then some Pharisees approached him to test him and asked him: "Is it lawful for a man to repudiate his wife for any reason?". And he replied: “Have you not read that the Creator created them male and female at first and said: This is why man will leave his father and mother and join his wife and the two will be one flesh? So that they are no longer two, but one flesh. Therefore what God has joined together, let man not separate ". They objected to him, "Why then did Moses order to give her the act of repudiation and send her away?" Jesus replied to them: “For the hardness of your heart Moses allowed you to repudiate your wives, but from the beginning it was not so. Therefore I say to you: Anyone who repudiates his wife, except in the event of a concubination, and marries another commits adultery. " The disciples said to him: "If this is the condition of man with respect to woman, it is not convenient to marry". 11 He replied to them: “Not everyone can understand it, but only those to whom it has been granted. In fact, there are eunuchs who were born from the mother's womb; there are some who have been made eunuchs by men, and there are others who have made themselves eunuchs for the kingdom of heaven. Who can understand, understand ”.
