There is a nascent movement among certain Q-anon influencer(s) that seeks to revive the 2,000 year old heresy that Christians are still under the Old Testament law. Evidently some folks prefer blog posts and YouTube videos to actually reading their Bibles. This is exactly why our culture is destitute and so easily manipulated; people have no idea how to actually read and study for themselves. Please don't play into (((their))) game.
Edit: For more context, read Acts chapter 15, Galatians (the whole thing), Romans 2, 3, 4, 5, 6, 7, and 8, Ephesians 2:15, Colossians 2:8-17
"Unto the Son he saith, Thy throne, O God, is for ever and ever" (Heb. 1:8).
Of course he's also the "Son of God", but all sides of this argument are well-known at c/Christianity. You can drop in there for more. He knows who all his sons and daughters are, and who they aren't.
