For those who are sad that the year-end news quizzes are past, here’s one to start 2014: If you have joined a church that preaches a Tulip theology, does that mean a) the pastor bakes flowers into the communion wafers, b) the pastor believes that flowers that rise again every spring symbolize the resurrection, or c) the pastor is a Calvinist?

As an increasing number of Christians know, the answer is “c.” The acronym summarizes John Calvin’s so-called doctrines of grace, with their emphasis on sinfulness and predestination. The T is for man’s Total Depravity. The U is for Unconditional Election, which means that God has already decided who will be saved, without regard to any condition in them, or anything they can do to earn their salvation.

The acronym gets no cheerier from there.

Evangelicalism is in the midst of a Calvinist revival. Increasing numbers of preachers and professors teach the views of the 16th-century French reformer. Mark Driscoll, John Piper and Tim Keller — megachurch preachers and important evangelical authors — are all Calvinist. Attendance at Calvin-influenced worship conferences and churches is up, particularly among worshipers in their 20s and 30s.
