Romans 1:26-27 For this reason God gave them up to dishonourable passions. Their women exchanged natural relations for unnatural, and the men likewise gave up natural relations with women and were consumed with passion for one another, men committing shameless acts with men and receiving in their own persons the due penalty for their error
Haydock: Ver. 26. God delivered them up. Not by being author of their sins, but by withdrawing his grace, and so permitting them, in punishment of their pride, to fall into those shameful sins. (Challoner) Ver. 27. Receiving in themselves the recompense…due to their error. That is, were justly punished for their wilful blindness and error, by which they had worshipped and adored creatures, instead of the Creator, idols instead of the one true God. (Witham)
Matthew Henry: 1:26-32 In the horrid depravity of the heathen, the truth of our Lord’s words was shown: Light was come into the world, but men loved darkness rather than light, because their deeds were evil; for he that doeth evil hateth the light. The truth was not to their taste. And we all know how soon a man will contrive, against the strongest evidence, to reason himself out of the belief of what he dislikes. But a man cannot be brought to greater slavery than to be given up to his own lusts. As the Gentiles did not like to keep God in their knowledge, they committed crimes wholly against reason and their own welfare. The nature of man, whether pagan or Christian, is still the same; and the charges of the apostle apply more or less to the state and character of men at all times, till they are brought to full submission to the faith of Christ, and renewed by Divine power. There never yet was a man, who had not reason to lament his strong corruptions, and his secret dislike to the will of God. Therefore this chapter is a call to self-examination, the end of which should be, a deep conviction of sin, and of the necessity of deliverance from a state of condemnation.
1 Corinthians 6:9 Do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived; neither the immoral, nor idolaters, nor adulterers, nor homosexuals,
Haydock commentary: Ver. 8-11. Defraud…your brethren. That is, you still make yourselves much more guilty by the injustices done to one another: for the unjust, and all they who are guilty of such crimes as I have mentioned, shall not possess the kingdom of God. And some of you were guilty of part of them, which have been washed off by your conversion, and your baptism, when you were justified. (Witham) — And such some of you were. It is probable that this was added by the apostle, to soften his preceding words, lest he might seem to accuse all the Corinthians of each of these sins, and he likewise adds, such indeed you were, but now you are washed, &c. &c. (Estius; St. Thomas Aquinas)
Matthew Henry Commentary: 6:9-11 The Corinthians are warned against many great evils, of which they had formerly been guilty. There is much force in these inquiries, when we consider that they were addressed to a people puffed up with a fancy of their being above others in wisdom and knowledge. All unrighteousness is sin; all reigning sin, nay, every actual sin, committed with design, and not repented of, shuts out of the kingdom of heaven. Be not deceived. Men are very much inclined to flatter themselves that they may live in sin, yet die in Christ, and go to heaven. But we cannot hope to sow to the flesh, and reap everlasting life. They are reminded what a change the gospel and grace of God had made in them. The blood of Christ, and the washing of regeneration, can take away all guilt. Our justification is owing to the suffering and merit of Christ; our sanctification to the working of the Holy Spirit; but both go together. All who are made righteous in the sight of God, are made holy by the grace of God.
1355 In the communion, preceded by the Lord’s prayer and the breaking of the bread, the faithful receive “the bread of heaven” and “the cup of salvation,” the body and blood of Christ who offered himself “for the life of the world”:181
Because this bread and wine have been made Eucharist (“eucharisted,” according to an ancient expression), "we call this food Eucharist, and no one may take part in it unless he believes that what we teach is true, has received baptism for the forgiveness of sins and new birth, and lives in keeping with what Christ taught."182
2357 Homosexuality refers to relations between men or between women who experience an exclusive or predominant sexual attraction toward persons of the same sex. It has taken a great variety of forms through the centuries and in different cultures. Its psychological genesis remains largely unexplained. Basing itself on Sacred Scripture, which presents homosexual acts as acts of grave depravity,141 tradition has always declared that "homosexual acts are intrinsically disordered."142 They are contrary to the natural law. They close the sexual act to the gift of life. They do not proceed from a genuine affective and sexual complementarity. Under no circumstances can they be approved.
2358 The number of men and women who have deep-seated homosexual tendencies is not negligible. This inclination, which is objectively disordered, constitutes for most of them a trial. They must be accepted with respect, compassion, and sensitivity. Every sign of unjust discrimination in their regard should be avoided. These persons are called to fulfill God’s will in their lives and, if they are Christians, to unite to the sacrifice of the Lord’s Cross the difficulties they may encounter from their condition.
2359 Homosexual persons are called to chastity. By the virtues of self-mastery that teach them inner freedom, at times by the support of disinterested friendship, by prayer and sacramental grace, they can and should gradually and resolutely approach Christian perfection.
