Frank Sheed presents one of the most clear explanations of the central doctrines of the Christian faith ever written. He starts with a case of good reasons for anyone to study theology, and the wonderful rewards that accompany such a pursuit.

After explaining how God is Spirit, Sheed examines God's infinity and man's creation from nothing. He then covers in depth such key doctrines as the Trinity, the Fall, the Incarnation and Redemption, the Mystical Body, Grace and the Sacraments, and the Last Things. His beautiful insights and clear explanations will help stir our minds to the inspiring truth of the spiritual realities at the centre of human existence.
