No Biblical Command. Pagan Origins. Deuteronomy 12:30-31 Forbids It.
"Take heed to thyself that thou be not snared by following them... How did these nations serve their gods? even so will I do likewise. Thou shalt not do so unto Yahuah thy Elohim." Deuteronomy 12:30-31
You cannot take pagan practices and "redeem" them for Yahuah. He says do not even ASK how the pagans worship. Do not do it. This is not a suggestion. It is a direct command.
There is no command anywhere in Scripture to celebrate His birth. No date is given for His birth. Shepherds were in the fields at night (Luke 2:8). This does not happen in late December in Judea.
"Learn not the way of the heathen... For the customs of the people are vain: for one cutteth a tree out of the forest, the work of the hands of the workman, with the axe. They deck it with silver and with gold." Jeremiah 10:2-4
While the direct context of Jeremiah 10 is idol carving, the principle of adopting pagan decoration applies. The pattern is unmistakable.
The Quartodeciman controversy (2nd century) documents the fight between those keeping Passover on Nisan 14 (the biblical date) and Rome pushing for Sunday Easter. The original believers kept the biblical date. Rome overrode them. This is historical fact, not speculation.
"Whereupon the king took counsel, and made two calves of gold, and said unto them, It is too much for you to go up to Jerusalem: behold thy gods, O Israel, which brought thee up out of the land of Egypt... And Jeroboam ordained a feast in the eighth month, on the fifteenth day of the month, like unto the feast that is in Judah... which he had devised of his own heart." 1 Kings 12:28, 32-33
Jeroboam did NOT reject Yahuah. He worshipped Yahuah in ways Yahuah never commanded. He created golden calves and said "Behold your gods who brought you out of Egypt." He created feasts "which he had devised of his own heart."
That is STILL idolatry. You cannot worship Yahuah using pagan methods. You cannot take a pagan date, a pagan festival, pagan symbols, and say "but we're doing it for the Messiah."
Modern Christianity follows the same pattern. Worships Yahusha using pagan dates, pagan symbols, pagan traditions. The intent may be sincere. But the practice is the sin of Jeroboam.
"For when they had slain their children to their idols, then they came the same day into my sanctuary to profane it." Ezekiel 23:39
The pattern: participate in pagan practice, then come worship Yahuah as if it is acceptable to mix the two. Christmas morning with pagan trees and gifts, then church service to "honor the Messiah." Easter sunrise service (sun worship) with eggs and rabbits, then "resurrection celebration." Ezekiel 23:39 describes this exact behavior.
Yahuah gave His people appointed times. Passover. Unleavened Bread. Firstfruits. Shavuot. Yom Teruah. Yom Kippur. Sukkot. These are HIS feasts (Leviticus 23:2). Not Jewish feasts. Not optional feasts. His feasts.
