All Christian people who identify as homosexual whom I know do confess their sin. But their sin doesn't include being who they are: homosexual women and men.
If they're engaging in homosexual sex, then yes - they do need to confess their sins. I've only encountered one homosexual debater in the last twenty years who has admitted confessing his homosexual liaisons as 'sin'.
There is no quote anywhere in the bible attributed to Jesus with regard to homosexuality. In fact, there is no bible quotation anywhere that mentions "homosexuality." None.
Strawman. A rose by any other name is still a rose.
As I mentioned earlier, Jesus is God. As God, Jesus is the one who gave Moses the Leviticus law against gay sexual relations to begin with; and he’s the one who inspires all Scripture (2 Timothy 3:16), including prohibitions against gay sexual relations in Romans 1:26-27 and I Corinthians 6:9-10, etc.
It’s also worth noting that Jesus didn’t mention wife beating or other sins such as pedophilia either, and there are not many folks who would argue he approved of those behaviors. So Jesus was under no obligation to reiterate the moral laws against homosexual sin that already existed, unless there were clarifications to be made.
Next, let's review the scriptures on gay sex sin:
Leviticus 18:22 - "Do not lie with a man as one lies with a woman; that is detestable."
Leviticus 20:13 - "If a man lies with a man as one lies with a woman, both of them have done what is detestable. They must be put to death; their blood will be on their own heads."
Romans 1:26-27 - "Because of this, God gave them over to shameful lusts. Even their women exchanged natural relations for unnatural ones. In the same way the men also abandoned natural relations with women and were inflamed with lust for one another.
Men committed indecent acts with other men, and received in themselves the due penalty for their perversion."
1 Corinthians 6:9-10 - "Do you not know that the wicked will not inherit the kingdom of God? Do not be deceived: Neither the sexually immoral nor idolaters nor adulterers nor male prostitutes nor homosexual offenders nor thieves nor the greedy nor drunkards nor slanderers nor swindlers will inherit the kingdom of God."
1 Timothy 1:8-10 - “But we know that the law is good if one uses it lawfully, knowing this: that the law is not made for a righteous person, but for the lawless and insubordinate, for the ungodly and for sinners, for the unholy and profane, for murderers of fathers and murderers of mothers, for manslayers, for fornicators, for
sodomites, for kidnappers, for liars, for perjurers, and if there is any other thing that is contrary to sound doctrine…”
Jude 7 – “In a similar way,
Sodom and Gomorrah and the surrounding towns gave themselves up to sexual immorality and perversion. They serve as an example of those who suffer the punishment of eternal fire.”
There's no gay marriages in the Old Testament; No gay marriages in the New Testament; no gay sex approved anywhere in the Bible. Just the opposite - gay sex is condemned in both testaments. God is consistent on that.
"The second-century BC Testament of the Twelve Patriarchs labels the Sodomites 'sexually promiscuous' (Testimony of Benjamin 9:1) and refers to 'Sodom, which departed from the order of nature' (Testament of Nephtali 3:4). From the same time period, Jubilees specifies that the Sodomites were 'polluting themselves and fornicating in their flesh' (16:5, compare 20:5-6). Both Philo and Josephus plainly name same-sex relations as the characteristic view of Sodom."
And to close:
“Whosoever shall be guilty of Rape, Polygamy, or Sodomy with man or woman shall be punished, if a man, by castration, if a woman, by cutting thro' the cartilage of her nose a hole of one half inch diameter at the least.” - Thomas Jefferson
