Leaven is one of those lovely miracles in God’s creation. Those of us who have baked homemade bread relish both seeing the dough rise and the smell. Culinary experts distinguish between yeast and natural leaven. Without going into the chemistry of the rising process, suffice it to say that they are different yet serve the same purpose, whether making fresh pizza dough, sourdough, or other kinds of bread.

So, how does this wonder of nature come to take on such a negative connotation in today’s Gospel story? Jesus uses the word “leaven” in the context of the miraculous feeding of the four thousand. (cf. Mark 8:1-9)

Then, shortly after this “feeding,” a group of Pharisees challenged Jesus. Unimpressed by his many miracles, they want a deeper explanation of what Jesus has been teaching and doing. We can hear the frustration in his voice as he interacts with these naysayers (cf. Mark 8:10-13).

Next, in this sequence of events, we find Jesus today in a teachable moment with his disciples. “Do you (too) not understand?” Jesus asks. And more:” Don’t be influenced, blinded by the misguided efforts of these religious leaders.” In this passage, Jesus refers to “bread” seven times. Then he gives the word “leaven” a paradoxical twist as something negative when referring to the words and intentions of these men.

For us, Jesus is the “bread of life.” When we eat the bread changed into his body at Mass, we remember his many actions and words—who he hung with, who he defended and healed, and the values he espoused (cf. the Sermon on the Mount). Let us learn from his challenging words today. May we go forth as leaven for good, healing, justice, compassion, and truth. And maybe bake some homemade bread.

Let Us Pray:

Lord Jesus, we are fortunate to have the perspective of the whole story—from all the healings, miracles, and teachings to your passion, death, and resurrection. May we hear your Word today. May we get it! May we understand and embrace its meaning for what we do today, whom we meet on the road, and how we spend our time. Thank you. Amen.
