I do not celebrate them any longer (Christmas, Easter, Halloween, etc.) In some things it may not be spot on, but for the most part I do believe it is pretty close. It is sun worship.
Besides, the big question that should be asked is why do believers celebrate these "holidays" when God has already ordained HIS Holy Day's for His people, that will be celebrated in His Kingdom, why not rejoice and celebrate these true Holy Days, since they seem very important to Him.
22 “For as the new heavens and the new earth
Which I will make shall remain before Me,” says the LORD,
“So shall your descendants and your name remain.
23 And it shall come to pass
That from one New Moon to another,
And from one Sabbath to another,
All flesh shall come to worship before Me,” says the LORD."
Isaiah 66:22-23
16 "And it shall come to pass
that everyone who is left of all the nations which came against Jerusalem shall go up from year to year to worship the King, the Lord of hosts, and to keep the Feast of Tabernacles. 17 And it shall be
that whichever of the families of the earth do not come up to Jerusalem to worship the King, the Lord of hosts, on them there will be no rain. 18 If the family of Egypt will not come up and enter in, they
shall have no
rain; they shall receive the plague with which the Lord strikes the nations who do not come up to keep the Feast of Tabernacles. 19 This shall be the punishment of Egypt and the punishment of all the nations that do not come up to keep the Feast of Tabernacles."
Zechariah 14:16-19
