Lies!
The prophylactic is not safe nor highly effective in the prevention of the transmission of HIV or any sexually transmitted infections or unplanned pregnancies. Rather, it promotes lust and every manner of sexual immorality and gives a false sense of security and even a pretended nobility to this most perverse tool of sexual license in Gaydom. The Condom is one of the greatest causes of sin, preventable disease, abuse, and murder (e.g. abortion) in our present, especially among the young. Its acceptance and diffusion is a terrible scandal leading innumerable souls to perdition, physical as well as spiritual.
"Thou shalt not commit adultery," says the Lord. Sexual sins are death to the soul and they also destroy the flesh itself! Chastity, Virginity and Celibacy are necessary virtues for world health. The World Health Organization is clueless. Cf. Proverbs 5-7, Matthew 19:12.
Condomastic sex is multiple adultery, it is more that one sexual sin, adding to the particular improper extra-marital sexual relation the distortion of the natural procreative end of marriage.
"...[W]hen [Onan] went in to his brother's wife [He] spilled his seed upon the ground, lest children should be born in his brother's name. And therefore the Lord slew him, because he did a detestable thing." Genesis 38:9b-10.
Condom use is detestable! It is dirty, shameful, abusive; it is mutual-masturbation; it is akin to sodomy. It is a grotesque misuse of what is meant to be the temple of God, the human body.
"Know you not that your bodies are the members of Christ? Shall I then take the members of Christ, and make them the members of an harlot? God forbid. Or know you not, that he who is joined to a harlot, is made one body with her? For they shall be, saith he, two in one flesh. But he who is joined to the Lord, is one spirit. Fly fornication. Every sin that a man doth, is without the body; but he that committeth fornication, sinneth against his own body. Or know you not, that your members are the temple of the Holy Ghost, who is in you, whom you have from God; and you are not your own? For you are bought with a great price. Glorify and bear God in your body." 1 Cor. 6:15-20.
May Christ Our Sweet and Blessed Lord and Our Lady, the Ever Virgin and Immaculate Mary, Mother of God and our Mother, save us!
