You can see all the lectionary readings for Proper 17, Year B by clicking here. I have chosen to discuss the passage from the Gospel of Mark.
In today’s passage Jesus is questioned by the Pharisees about his followers eating without following particular hand washing rituals. We know from previous passages that they aren’t asking this question casually but are no doubt trying to trap Jesus again. They are angry his followers aren’t following ancient tradition as they think it should be followed. (Am I the only one who wants to sing the “Tradition” song from Fiddler on the Roof every time I think of tradition?)
Jesus claps back as only Jesus can and calls them hypocrites and quotes Isaiah saying they only honor God with words and not in reality. He says they prefer man-made rules instead of God’s commands.
This reminds me of so many Christian leaders today who are vocal in our culture with rules that they think everyone should follow–such as rules regarding sexuality or gender. The hill they will choose to die on is whether or not homosexuality is a sin or whether or not women should be equal to men, rather than to care for the poor and to seek to correct injustice. They choose to follow narrow manmade rules that oppress rather than life-giving abundant rules to work for the good of all humanity.
