You would use the accomplishments of Jesus Christ (the verses you shared) which broke God's chosen away from religion to justify your thinking?! Where did you get your training?! Christmas is religious! (Do you know the difference between a genuine relationship with God as His child and religion?) Who (in the world) dictated Christmas is an HOLYDAY?! Again, religious. (Actually it was given to us by the Roman Catholic Church not that long after it was founded around the mid 4th century under Constatine. The blending of pagan practices into Christianity. For political convenience.) No "Pope," no man is above God's Word. Jesus was born on September 3rd. 3 BC. And it doesn't take tracking the astronomy of Revelation 12:1 to see it. Just knowing the culture concerning the shepherds that came to see the baby Jesus should show he wasn't born in December for most. They're in the fields with the flocks right after the harvest for about a month. So the critters can feed on what got left behind and their dung would fertilize the fields. NOT at the beginning of winter. They'd freeze their butts off! And it gives virtually no time for the dung to break down. And the wise guys didn't show up until Jesus was a toddler. In Bethlehem.
But who/what do traditions say was born on December 25th? Horus 3000 BC, Osiris 3000 BC, Attis 1400 BC, Zarathustra 1000 BC, Heracles 800 BC, Mithra 600 BC, Buddha 563 BC, Tamuz 400 BC, Dionysus 186 BC, and there's more.
You do realize Satan is the god of this world of men, right? I pray you see the pattern. He seems to have a liking for the birth of his false gods to be on December 25th.
Do what you will with the truth. It can get prickly, I know. I pray I'm wrong, but you seem to want to defend your error. That you're comfortable with it. I feel like I'm casting pearls where they don't belong.
