Today we hear James warn against selfish ambition, while the disciples quarrel over which one of them is the greatest. Jesus tells them the way to be great is to serve. Then, to make it concrete, he puts in front of them a flesh-and-blood child. We are called to welcome the children God puts in front of us, to make room for them in daily interaction, and to give them a place of honor in the assembly.

 

Mark 9:30-37

30[Jesus and the disciples went on] and passed through Galilee. He did not want anyone to know it; 31for he was teaching his disciples, saying to them, “The Son-of-Man is to be betrayed into human hands, and they will kill him, and three days after being killed, he will rise again.” 32But they did not understand what he was saying and were afraid to ask him.
33Then they came to Capernaum; and when Jesus was in the house he asked them, “What were you arguing about on the way?” 34But they were silent, for on the way they had argued with one another who was the greatest. 35He sat down, called the twelve, and said to them, “Whoever wants to be first must be last of all and servant of all.” 36Then he took a little child and put it among them; and taking it in his arms, he said to them, 37“Whoever welcomes one such child in my name welcomes me, and whoever welcomes me welcomes not me but the one who sent me.”
