Ohh and......
Furthermore The passage from Mark is Talking specially to the Pharisees and Scribes, lets read on for a further analysis, shall we?
The Pharisees and scribes were under the law. That’s what Mark 7:3 was referring to when it says, “holding the tradition of the elders".
Religious people who are like the Pharisees are self-righteous because they think they are better than others. They should consider that they are sinners, rightly related to God only because of the mercy and grace that is in Christ Jesus. They actually think that their righteousness comes from their keeping of these external human traditions. They also become very critical of others who do not keep the human traditions the way that they do. The Pharisees were very critical and condemning. They even condemned Jesus because He did not observe their religious traditions.
Mark 7:5 says, “Then the Pharisees and scribes asked him, Why walk not your disciples according to the tradition of the elders, but eat bread with unwashen hands?”
Read and quote the Bible in its context otherwise we can interpretate it as we wish. This passsage from Mark has nothing to do with the traditions St Paul was talking about, Mark was referring to the Law.
