In Matthew 15:1-20 and Mark 7:1-23, when the examiners from Jerusalem came to Jesus (presumably still at Gennesaret) to quiz Him about His beliefs, they started with the wrong question:
"Why do your disciples break the tradition of the elders?"
The disciples didn't wash their hands before they ate, apparently.
Good tradition. Good hygiene. Nothing wrong with it. Just not law. You won't find it as a command in the Old Testament, except for Aaron and his sons before performing the sacrifice. It was tradition.
Jesus' answer was itself a question: "And why do you break the command of God for the sake of your tradition?"
Then He went on to decry their "Corban" tradition, saying that it nullified the law of God, which was to provide for aging parents. God could get by without the money.
He said, "And you do many things like that."
The principle I draw from this is that there may be nothing intrinsically wrong with a tradition, but it is wrong to attribute it to God and enforce it as law ... and when it comes to a showdown between what God wants and what man wants, God must win.
Do we Christians do many things like that?
