It is sad to see so many trads defend and make excuses for mortal sin of sodomy.  

Sodomites have taken over the Church.   There are more sodomite friendly parishes than Traditional Latin Masses worldwide.  

I thought the church taught that all sins are forgiven? How can sodomy not be forgiven, plus I think most married couple have committed that sin (oral on wife, which can been seen as sodomy)

(. . .)

For nothing is so displeasing to God as an impenitent heart. Impenitence is the one sin for which there is no forgiveness. For if one who ceases to sin is pardoned even after he has sinned, and if prayer has power to bend the judge; it follows that every impenitent sinner must provoke his judge to wrath. Thus despair is the one sin for which there is no remedy. By obstinate rejection of God's grace men turn His mercy into sternness and severity. Yet, that you may know that God does every day call sinners to repentance, hear Isaiah's words: "In that day," he says, "did the Lord God of Hosts call to weeping and to mourning and to baldness and to girding with sackcloth: and behold joy and gladness, slaying oxen, and killing sheep, eating flesh, and drinking wine; let us eat and drink, for tomorrow we shall die." After these words filled with the recklessness of despair the Scripture goes on to say: "And it was revealed in my ears by the Lord of Hosts, Surely this iniquity shall not be purged from you till you die." Isaiah 22:12-14 Only when they become dead to sin, will their sin be forgiven them. For, so long as they live in sin, it cannot be put away.

83. Now the man who, not believing that sins are remitted in the Church, despises this great gift of God's mercy, and persists to the last day of his life in his obstinacy of heart, is guilty of the unpardonable sin against the Holy Ghost, in whom Christ forgives sins. But this difficult question I have discussed as clearly as I could in a book devoted exclusively to this one point.

4. And speak not to me of those who have committed small sins, but suppose the case of one who is filled full of all wickedness, and let him practice everything which excludes him from the kingdom, and let us suppose that this man is not one of those who were unbelievers from the beginning, but formerly belonged to the believers, and such as were well pleasing to God, but afterwards has become a fornicator, adulterer, effeminate, a thief, a drunkard, a sodomite, a reviler, and everything else of this kind; I will not approve even of this man despairing of himself, although he may have gone on to extreme old age in the practice of this great and unspeakable wickedness. For if the wrath of God were a passion, one might well despair as being unable to quench the flame which he had kindled by so many evil doings; but since the Divine nature is passionless, even if He punishes, even if He takes vengeance, he does this not with wrath, but with tender care, and much loving-kindness; wherefore it behooves us to be of much good courage, and to trust in the power of repentance. For even those who have sinned against Him He is not wont to visit with punishment for His own sake; for no harm can traverse that divine nature; but He acts with a view to our advantage, and to prevent our perverseness becoming worse by our making a practice of despising and neglecting Him. For even as one who places himself outside the light inflicts no loss on the light, but the greatest upon himself being shut up in darkness; even so he who has become accustomed to despise that almighty power, does no injury to the power, but inflicts the greatest possible injury upon himself. And for this reason God threatens us with punishments, and often inflicts them, not as avenging Himself, but by way of attracting us to Himself. For a physician also is not distressed or vexed at the insults of those who are out of their minds, but yet does and contrives everything for the purpose of stopping those who do such unseemly acts, not looking to his own interests but to their profit; and if they manifest some small degree of self-control and sobriety he rejoices and is glad, and applies his remedies much more earnestly, not as revenging himself upon them for their former conduct, but as wishing to increase their advantage, and to bring them back to a purely sound state of health. Even so God when we fall into the very extremity of madness, says and does everything, not by way of avenging Himself on account of our former deeds; but because He wishes to release us from our disorder; and by means of right reason it is quite possible to be convinced of this.

Yes yes there is no forgiveness to impenitence, but how does that prove that there's no forgiveness for penitent sodomites? Believing that mortals sins can be forgiven through Confession is not saying they aren't mortals sins, it's just Catholic doctrine.

I'm not a sodomite, I was just arguing against the notion that it was an unforgiveable sin even in penitence.

....with the exception, of course, of the unforgivable sin!

4. As therefore we abhor the Arians, who maintain a difference between the Father and the Son, so also we abhor the Macedonians , who, although they ascribe equality to the Father and the Son, yet think the Holy Ghost to be of a lower nature, not considering that they thus fall into that blasphemy, which is not to be forgiven either in the present age or in the judgment to come, as the Lord says: "whosoever shall have spoken a word against the Son of Man, it shall be forgiven him, but he that shall have spoken against the Holy Ghost, it shall not be forgiven him either in this age or in the age to come Matthew 12:32 ." And so to persist in this impiety is unpardonable, because it cuts him off from Him, by Whom he could confess: nor will he ever attain to healing pardon, who has no Advocate to plead for him. For from Him comes the invocation of the Father, from Him come the tears of penitents, from Him come the groans of suppliants, and "no one can call Jesus the Lord save in the Holy Ghost 1 Corinthians 12:3-6," Whose Omnipotence as equal and Whose Godhead as one, with the Father and the Son, the Apostle most clearly proclaims, saying, "there are divisions of graces but the same Spirit; and the divisions of ministrations but the same Lord; and there are divisions of operations but the same God, Who works all things in all 1 Corinthians 12:3-6 ."
