Last week the disciples argued among themselves about who’s the greatest. This week, they’re complaining about this other guy, this stumbling block to their status, power, and recognition. Today’s gospel is a continuation of last week’s story, and a variation on last week’s argument. Jesus and the disciples are still in the same house as last week, the child is still on Jesus’ lap, and Jesus is still deepening and moving the conversation inward. John, however, wants to make the conversation about this other guy, this stumbling block. “Teacher, we saw someone casting out demons in your name, and we tried to stop him, because he was not following us.” 

Isn’t that what we often do or want to do with our stumbling blocks? We draw lines in the sand, circle the wagons, divide into us and them, and try to stop them. I see that happening in the world today. I read it in the news. And I’ve done it. I’ve been John, haven’t you? Jesus, however, takes a different approach. He erases the line and enlarges the circle. He isn’t so concerned about another who causes us to stumble. His concern is focused on us, not the other, and it’s twofold—first, whether we have become a stumbling block to another, “to one of these little ones,” to the child sitting on his lap, and, second, whether we have become a stumbling block to ourselves. 

Jesus is once again asking us to look at ourselves, to be self-reflective. It’s as if he saying to John, “Don’t you worry about that other guy. You worry about yourself.” He’s asking us to look within. The greatest stumbling blocks are not outside us but within us: anger and revenge, the judgments we make of others, prejudice, our desire to get ahead and be number one, the need to be right, our unwillingness to listen, the assumption that we know more and better than another, living as if our way is the only and right way, pride, fear, being exclusionary, our busyness, lies, gossip, our desire for power and control. These, and a thousand other things like them, are what cause others and us to fall. 

In what ways have you and I become stumbling blocks to another or to ourselves? That’s the unspoken question in today’s gospel. When have we caused another to trip and fall? When have we tripped and stumbled over our own two feet, our own life?
