By Joannie Watson, Integrated Catholic - This Sunday, the Mass readings revolve around the theme of being called and sent. God calls Isaiah in the first reading, Paul in the second, and Peter in the Gospel. As I reread the readings, both fairly familiar stories, I was struck by a detail: all were unworthy for the mission, and all recognized their unworthiness.... Discipleship is a buzz word in the Church these days. There are a dozen ministries popping up, all touting to help dioceses and parishes form disciples.
