Alamo-Girl posted that Christ taught against some tradition as recorded in Mark 7, 1-13.
Since my mother and some other relative are Jewish, I had an interest in His teachings from that POV when I first read the Gospels. It was my impression that He upheld Jewish law, mostly in the Spirit of God rather than the nitpicky legalism it had devolved to.
I couldn’t remember any record of traditions, but Alamo-Girl found that passage in Mark. It does mention Christ using the word “tradition” in the KJV, but I’m thinking it was another attempt to trap him in law-breaking...I’m going to see what the literal translation is, if I can find it, because this is a matter of personal interest to me.
