The May 2012 issue of Tabletalk addresses the subject of controversy. John Newton’s letter “On Controversy” provides a launching pad into the discussion, and the core of this issue extracts, explains, and applies the three major sections of the letter that he wrote to a minister preparing to engage another minister regarding orthodoxy. An additional two articles argue for the occasional necessity of controversy and direct us to the appropriate end of engaging in controversy: the glory of God. Contributors include R. C. Sproul, Sinclair Ferguson, Collin Hanson, Keith Mathison, Al Mohler, Robert Rothwell, R. C. Sproul Jr., and Justin Taylor.
