Book excerpt: The life of Christian discipleship begins at Baptism. Through the life-saving waters, a new Christian is freed from sin, shares in the death and Resurrection of Christ, and is made a member of the Body of Christ, the Church. But, with this gift from God comes important responsibilities. This short booklet explores the Catholic understanding of the Sacrament of Baptism and the baptized Christian's important role in sharing the light of Christ. The questions at the end of each short chapter will help readers reflect upon what it means to be a Christian disciple in the world today, living lives of justice, charity, and love.
