Here is my advice to you: keep reading, pal.
You don’t even need to turn the page in your bible. Look at Chapter 2 and verse 1, where Paul tells you that, if you’re passing judgment on those exact people that you describe in your haughty little yellow card, you have no excuse yourself – because you also sin. To quote Paul, “..do you think you will escape God’s judgment?”
And keep reading in Chapter 3 – where we learn that God is revealing a new righteousness in Jesus to all who believe “for all have sinned and fall short of the glory of God, and all are justified freely by his grace through the redemption that came by Christ Jesus.”
Keep reading in Chapter 15, where Paul urges us to “accept one another, then, just as Christ accepted you, in order to bring praise to God.”
In short, if you’re going to quote Paul’s letter to the Romans, then you should at least bother to have a vague idea of what that letter is about. And when you do read it, you might be surprised at what it is really saying about the way you treat people who are different from you.
I suspect this is a difficult concept, but you might even try being compassionate toward people who are homosexual. I seem to have a vague recollection that ideas like compassion, love, and inclusiveness were important in Jesus’ ministry, but I might be wrong…
