anything that "takes away from" or "distracts" from Christ (and his glorious coming to earth as a humble king) is, by definition, "anti-christ". Ironic too - though insignificant in reality, is that Santa & Satan share the same letters.
I really liked this Bible study except one thing. I didn't agree with is that we are the Bride of Christ. I believe we are the sons of God. I see the Bride as the Jews that will be saved (and added) after the rapture of the church.
