what bother me is the pagan origin.Why we Christians can't have Christian rock? Because its origins are evil.Do you think that God can build on any corrupt foundation?

Look here Exodus 34:12-13

"Take heed to thyself, lest thou make a covenant with the inhabitants of the land whither thou goest, lest it be for a snare in the midst of thee:But ye shall destroy their altars, break their images, and cut down their groves:"
Why God is telling Israel to destroy their altars and not to change them and make them for him?

2cor 6:14-16 says
"Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness? And what concord hath Christ with Belial? or what part hath he that believeth with an infidel? And what agreement hath the temple of God with idols? for ye are the temple of the living God; as God hath said, I will dwell in them, and walk in them; and I will be their God, and they shall be my people"

And here is the question I need we Christians to discuss:
If Xmass day wasn't the day messiah was born,then what fellowship hath with Jesus?
