In that first clip, Charlie is referring to the Leviticus 19 passage that is often translated a few different ways, which says "Do not hate a fellow Israelite in your heart" or some form of "countryman" instead of Israelite. That's not the same as the quote from Jesus, which is contained in multiple Gospels, that he calls his followers to "love your neighbor as yourself." There is a very distinct difference between the two, in that the quote from Jesus is inclusive of all humans, not just Israelites, and extends that compassion to others no matter their nationality, race or ethnicity. It was a radically different commandment with a universal purpose than the one from Leviticus, which is what Charlie quotes, and I'm sure there's a good reason why he likes that verse instead. So telling Miss Rachel to go "crack open that Bible" as if she didn't know what the "love they neighbor" text meant, is just the cherry on top of the patronizing misinterpretation of her words and a complete misunderstanding of his own religion.
That's not even getting into the whole old law vs new law discussion, and what still applies to the modern day law based on Jesus' teachings. Or even looking at all the examples of Jesus interacting with the sinful people and helping them regardless of if they were living in sin. It's just astonishing how modern day Christians have completely bastardized the teachings of Jesus and twisted it to reinforce their own bigotry and vengefulness against groups of people they love to hate.
