The sacraments have always been a point of contention in the church. Someone once said that the sacraments serve as a litmus test of the strength or weakness of a system of theology. This is because many aspects of what we believe, such as the doctrines of God, of Christ, of the Spirit, of Scripture, of the Church, and even of eschatology converge here and find practical outlets.
"Religion that is pure and undefiled before God, the Father, is this: to visit orphans and widows in their affliction, and to keep oneself unstained from the world" (Jam. 1:27).
There is a lot to like about the story of John Newton. And Simonetta Carr and Amal tell and illustrate it beautifully (Reformation Heritage Books, 2018). Newton first told the story himself in an 18th century best-seller. A young man with a dead mother and hard-to-please father pursues riches and adventure at sea. After several brushes with death Newton--who married the love of his life--left the sea to pursue poetry and preaching.
In writing A Secular Age, Charles Taylor has slowly, and thoroughly built what is in essence his life's work. He first lays out the terms that he intends to work with in defining secularism. This is more than what flies in public spaces, and the decline of belief and practice.
