Most of today’s Catholic teaching on grace starts from Thomas Aquinas’ treatise in six questions of the Summa Theologiae. The most difficult part of his treatise deals with what theologians came to call actual grace. Profoundly paradoxical issues arise at every turn about the co-operation of God and man in Christian behavior. This course, without ignoring Aquinas, sets out from a different starting point – the New Testament. Scripture clarifies what can otherwise tend to remain obscure and opens a way for the Christian to know Jesus Christ and the power of his rising – that is, to live the life of grace.
