There are two calls of Peter related in the Gospels. The first occurrence is at the start of Jesus’ ministry (Mark 1: 16-18). The second occurrence is after the resurrection in today’s Gospel.
Three years separated those two calls and during that time a lot of things had happened to Peter. He had found out a lot about the man who had called him, about the task to which he had called him and all about himself. When the second call came Peter was a wiser and humbler man and therefore his second ‘yes’ was far more mature and enlightened than his first ‘yes’ had been.
Peter’s story is one of calling, falling and recalling. It shows that Christ’s call doesn’t exclude falls. A vocation is not something one hears once and answers once. A call has to be heard many times and responded to many times. Each day a part of the chosen path opens up before us. A part we have not traveled before. As one goes on the call gets deeper and the response becomes more internal and personal.
Peter is a great consolation to us. Courage fails us all. In the end all of us are mere mortals who are inconstant in our belief. We must learn to forgive ourselves, our moments of weaknesses and failures. We must not judge ourselves or others by momentary lapses and work as Peter did to look after our brothers and sisters in our community.
