I love the entrance antiphon for today's feast: "As he walked by the Sea of Galilee, Jesus saw James, the son of Zebdee, and John, his brother, mending their nets and he called them."
These brothers must have been close. Both respond without hesitation to the call of Jesus. Both also have a mother who wanted both of her sons to sit on either side of Jesus when he came into his kingdom. When Jesus asks John and James if they can drink the chalice that he is going to drink, the reply, "We can."
When the other ten apostles find out about the request, they are indignant. But Jesus uses the occasion to tell them that "whoever wishes to be great among you shall be your servant; whoever wishes to be first among you shall be your slave. Just so, the Son of Man did not come to be served but to serve and to give his life as a ransom for many."
Jesus has given us so many lessons in humility. Am I humble? We are to learn from him who is meek and humble of heart.
