The One and Triune God

There are few doctrines more central to the Christian faith than the Trinity. Affirmations of belief in the Father, Son, and Holy Spirit are at the heart of the Church’s creed. And yet there are also few doctrines of the Church less understood and appreciated than that of the Trinity. This course helps to explain some of the basic doctrines of the Church concerning the unity among and diversity between the Father, Son, and Holy Spirit.
