Holy Baptism is the sign of new life in Christ. Baptism unites Christ with his people. That union is both individual and corporate.
All baptized persons are part of the Laos, the people of God, and all are called to bring to others the good news of God’s love. All Christians are called to ministry and the baptismal covenant (BAS, page 158-159) describes in detail the obligations of this call.
