Then why include the OT at all if it’s pretty much retconned?
It’s historical text of great importance, and the old law isn’t the only thing that’s in there. God still works amazing things in those peoples lives and their stories held in those books have great power. Also, if you’re unaware, Gideons pocket Bibles for spreading the gospel are just New Testament + Proverbs and Psalms.
Also LOL; that sentence in Star Wars context would be sacrilege!
