Well actually....no...it's not. Leviticus 18:22 for example is written "
V'et zachar lo tishkav mishk'vey eeshah toeyvah hee." The literal translation is "
And with a male you shall not lay layings of a woman"
Now...no one has any idea what it means to "lay layings" so using Midrash (that convenient tradition the Church uses to...ahem....
interpret things that don't make sense or are missing) they just tossed in three little words "as with the" and translated it "
And with a male you shall not lay (as with the) layings of a woman". Ok well now it makes sense but unfortunately that's not what is written.
Secondly the word used to describe the alleged sin is "
toeyvah" which
can mean abomination. When used in the context of ritual, however, it is more accurately translated as "unclean"...."ritually improper", "ceremonially impure", etc. When you consider that at Leviticus 18:21 it begins discussing rituals practiced to Moloch and you put 18:22 in context with 18:21 (as fundamentalists generally refuse to do) then whatever act 18:22 is warning against, it is in reference to pagan ritual and as such the transgression would not be considered an "abomination" but would simply be "ritually improper". Sexual activity in pagan ritual including orgies, homosexual acts male or female, etc were pretty common in those days. In fact the temples kept prostitutes in their employ so people could properly fulfill their ritual obligations to the gods. Rituals to Moloch frequently involved this kind of stuff.
So in other words if you a) take 18:22 out of the context of 18:21 and look at the verse in isolation, b) ignore the cultural context of the times and the sexual activities involving pagan ritual, and c) add words to the original scripture to...ahem..."clarify it (in other words change it completely)...then yes; 18:22 condemns male-male homosexuality as an abomination. And indeed, that's precisely what the Church has done.
If you look at it in context, consider the culture of the day, and read the verse as it's written then actually it doesn't say a word about condemning homosexuality at all...at least not in the context that we are talking about in this day and age. The
best someone could argue is that it
might since the verse itself makes no sense, but in context it would only be in regard to pagan ritual anyhow. The Church will tell you to ignore those who point out these truths and tell you they are Satan's minions who will be leading to into hell (which of course is another one of the Church's bullshit creations but that's another story) pretty much because the Church is interested in power, control, money, and obedience and accurate reporting of the word of God has very little to do with it.
So there goes that 100% thing you were talking about 'cause the Leviticus argument that it condemns homosexuality is a bunch of bullshit. Now....want me to discuss Paul's bullshit verses or have you gotten the point?
Let me recommend for you a fine book that explains all this in far more detail:
