Whether one doesn't want to confront whether homosexuality is like telling a fib or stealing a pen from work, leave such value judgments aside, and read what the word of God states is the character of such sin. I haven't noticed this much said of any sin common to man, again, what man thinks worse or not immaterial. Here is what God says,
Romans 1:21-32 Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened. Professing themselves to be wise, they became fools, And changed the glory of the uncorruptible God into an image made like to corruptible man, and to birds, and fourfooted beasts, and creeping things. Wherefore God also gave them up to uncleanness through the lusts of their own hearts, to dishonour their own bodies between themselves: Who changed the truth of God into a lie, and worshipped and served the creature more than the Creator, who is blessed for ever. Amen. For this cause God gave them up unto vile affections: for even their women did change the natural use into that which is against nature: And likewise also the men, leaving the natural use of the woman, burned in their lust one toward another; men with men working that which is unseemly, and receiving in themselves that recompence of their error which was meet. And even as they did not like to retain God in their knowledge, God gave them over to a reprobate mind, to do those things which are not convenient; Being filled with all unrighteousness, fornication, wickedness, covetousness, maliciousness; full of envy, murder, debate, deceit, malignity; whisperers, Backbiters, haters of God, despiteful, proud, boasters, inventors of evil things, disobedient to parents, Without understanding, covenantbreakers, without natural affection, implacable, unmerciful: Who knowing the judgment of God, that they which commit such things are worthy of death, not only do the same, but have pleasure in them that do them.
If you don't take into account this real treatise in scripture, and the bedfellows of such sin, the explicit spiritual state, then throw out the scripture. But therein is the truth, and it matters not one whit what silk hat men put on a pig, how much man philosophizes, it's only God's opinion that counts, not yours, not mine, if any such opinion is contrary to the Lord's. This much is not rocket science. If anybody finds the picture in this scripture pretty, I'm not getting that. This is not a worse sin or not issue, to determine what is politically correct and stuff into man's understandings: it's an issue of God's truth and huge, serious implications to the souls of people this scripture spells out.
