Some famous person, I'm sure at some point said this, I don't know who it was, said, if you refuse to learn from the past, you'll be doomed to repeat it constantly, something to that effect, but we see this, I mean, from Luke's gospel account, we see the same thing that happened in history with the Reformation, right, I mean, the leaning on the tradition, and then we see it repeated over and over and over, I mean, you almost literally, from the text we read earlier, a person literally almost has to be intentionally blind and deaf to the reality of the consistency, if you would have it, in the repetition of the same sin by the quote unquote church throughout history, a movement away from the scripture to tradition, or even trying to make a balanced approach, that was the whole deal with the Pharisees, because their deal with, in Mark, your disciples didn't wash their hands, Jesus spoke up and he communicated clearly to them, and he said, you're talking about the tradition of the elders, and that tradition of the elders, I'm sure you know this, but some of our listeners may not, that tradition of the elders that's spoken of, I mean, that's in single quotes there in the text, but in any case, he is speaking about the oral tradition.
