The Gospel of Mark seems to place the disciples in a constant state of disbelief and misunderstanding. They just don’t seem to get what Jesus is on about. In the Gospel today we catch a glimpse of the stupidity of the disciples. Mark gives us the opening clue – they forgot to bring bread. So when Jesus says to be aware of the yeast of the Pharisees they were wondering about the amount of bread they brought with them!
Yeast was a common metaphor for evil and corruption. A little yeast was mixed in with the batch of flour and water to assist the dough. A little corruption on the part of the Pharisees could see the rising of anger and dissension among the people of the nation to see Jesus put to death.
Be aware of the yeast of the Pharisees – the teaching and false interpretation they give in order to persuade other from the truth. If we are not strong in our faith we are too often swayed by every kind of strange doctrine. We must seek to learn and understand our faith. At times we are called to give an answer for our belief as Catholics. Many do not understand and will look to us to counsel and advice.
People will have opinions and interpretations of one kind or another. We should allow our conscience be formed in those resources available to us – bible, teachings of the Church, the Catechism and tradition of the Church. Our lives must be formed in truth and not corrupted by the yeast of false interpretation and misleading doctrine
