=chinie19;12791793]I know what it is mortal sin, but I don’t understand how could it be the same to have an abortion or kill someone, than to have intimacy with your fiance.
Shall I go to hell in both cases?
YES!

Why? [UNLESS repented, confessed and forgiven]
Because God is as God MUST BE; Just and Fair.
Isaiah 55: 6-11 “Seek ye the Lord, while he may be found: call upon him, while he is near. Let the wicked forsake his way, and the unjust man his thoughts, and let him return to the Lord, and he will have mercy on him, and to our God: for he is bountiful to forgive.
For my thoughts are not your thoughts: nor your ways my ways, saith the Lord. For as the heavens are exalted above the earth, so are my ways exalted above your ways, and my thoughts above your thoughts. [And as the rain and the snow come down from heaven, and return no more thither, but soak the earth, and water it, and make it to spring, and give seed to the sower, and bread to the eater: So shall my word be, which shall go forth from my mouth: it shall not return to me void, but it shall do whatsoever I please, and shall prosper in the things for which I sent it”
Sex is a gift from God with two goals: Procreation AS A POSSIBILITY [God’s option] and marriage Unity:
It boils down to this:
Who;s In CHARGE?
Our All Wise God gives us only TWO options:
Either He is permitted to be OR we assume those risk ourselves.
Our Catechism
2399 The regulation of births represents one of the aspects of responsible fatherhood and motherhood. Legitimate intentions on the part of the spouses do not justify recourse to morally unacceptable means (for example, direct sterilization or contraception).
1652 “By its very nature the institution of marriage and married love is ordered to the procreation and education of the offspring and it is in them that it finds its crowning glory.”
“Children are the supreme gift of marriage and contribute greatly to the good of the parents themselves. God himself said: “It is not good that man should be alone,” and “from the beginning [he] made them male and female”; wishing to associate them in a special way in his own creative work, God blessed man and woman with the words: “Be fruitful and multiply.” Hence, true married love and the whole structure of family life which results from it, without diminishment of the other ends of marriage, are directed to disposing the spouses to cooperate valiantly with the love of the Creator and Savior, who through them will increase and enrich his family from day to day”
When God Choose to Create man He commanded them:Gen. 1:28 “And God blessed them, saying: Increase and multiply, and fill the earth, and subdue it, and rule over the fishes of the sea, and the fowls of the air, and all living creatures that move upon the earth”
One can understand that from God’s perspective that prohibiting POSSIBLE conception is as egregious to Him as is Murder.
Sex is in a sense “marriage cement” intended to reward and bind those in closeness to each other and to God Himself.
