A recent blog by Mark Jones cited an article by Dr. Richard A. Muller, How Many Points? which I heartily recommend.
Dr. Muller rightly notes that many today who tout themselves as “Calvinists” actually espouse very little of Calvin’s theology, and, as he put it, would have gotten themselves tossed out of Geneva if they arrived there at any time during the late sixteenth or the seventeenth century. Too many, I suspect, are unwittingly like the pastor Dr. Muller encountered: simply American evangelicals, without much awareness of, or interest in, the Reformed confessional standards.
