I think hes pointing out the hypocrisy bud. It’s outside of the Bible and is European (pagan if u will). The truth stands alone u must accept this even if u continue to celebrate.
"One man esteemeth one day above another: another esteemeth every day alike. Let every man be fully persuaded in his own mind.
6 He that regardeth the day, regardeth it unto the Lord; and he that regardeth not the day, to the Lord he doth not regard it. He that eateth, eateth to the Lord, for he giveth God thanks; and he that eateth not, to the Lord he eateth not, and giveth God thanks"
Its a sin to celebrate Christmas if you believe its against God. Not because some loud mouth pastor said so. Plus he still didnt say not to worship Jesus at all. Worshipping "Jesus" as God while berating his church members isnt something he should be doing
