People like the woman at the head of the Disciples of Christ denomination will browbeat you into thinking that the RFRA encourages Christians to spurn sinners, the very people Jesus spent His time with while on earth, instead of helping them. (We'll set aside the irony of this argument from liberal Christians, who do not even consider homosexuals to be engaging in sin…)
No faithful Christian is suggesting that we ought to avoid associating with sinners, or even decline to serve them. That's the wrong question. We are to be friends of sinners. The question is not one of whether or not we are to love sinners. The question is, What qualifies as participating in and promoting ungodliness?
