What are you basing your biblical epistemology on? Clearly not on the Scripture, since they thoroughly condemn homosexuality. Clearly not Holy Tradition, since it thoroughly condemns homosexuality. The only possible way you could reach this conclusion is if you interpret the Bible based on what secular society tells you or what you personally believe. To which I say, what not cut out the middleman? If you're going to believe whatever you want to believe regardless, then what use is there for the Bible and the Church? At that point, Christianity doesn't even exist. Christianity is basically just whatever you want it to be. Hence, the reason you are not a Christian. You do not change for Jesus. Instead, you ask Jesus to change for you.
