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
Don't care. Every man hath a psalm every man a doctrine. Read the Bible, walk humbly with God, seek to do good and get rid of the fear.
