Baptism is the first Christian sacrament. As sacrament it mediates Christian faith and Christian identity, in Christ and in the Church. This course unit presents an introduction to sacramental theology, taking baptism as a paradigm. It will explore baptism as gift of the Holy Spirit and sacrament of salvation, and ask about the consequences of the mutual recognition of baptism by the different Christina churches and communities. Consideration will also be given to the development of Confirmation as a separate sacrament in the west.
