I have recently been teaching both our men's and women's groups by using John Piper's "Desiring God." Its a pretty good book but I am reminded again and again why Reformed Baptists need to re-appraise themselves in regard to the Reformed tradition. In fact, though I believe they are "Calvinistic" they are not strictly "Calvinists." Why do I say this (and I really am not trying to offend my Baptist brethren whom I love dearly)? Because Calvin placed great emphasis, GREAT EMPHASIS, on the sacraments and Baptists (no matter how hard they try) do not.
Take John Piper as an example. He writes in "Desiring God" that worship is a feast. I want to say up-front that I do appreciate his emphasis on "reception" in worship as opposed to the typical Kantean idea of us giving something to God in worship, as though receiving from God is selfish and sub-Christian. On page 109 he says:
I thank God that again and again He has awakened my heart to desire Him, to see Him, and to sit down to the feast of Christian Hedonism and worship the King of Glory. The banquet hall is very large.
What does this feast consist of? He writes on page 104, "Good sermons and hymns and prayers express and inspire worship." Try as hard as I might, I found no mention whatsoever of the sacraments. Look, I'm not trying to be a rump but Piper uses the language of worship as a feast...a feast. And so the element in worship that is commanded by our Lord which is actually a feast, the Lord's Supper, is nowhere to be found in Piper's section on worship. I find this strange and telling and the implications are interesting for Presbyterians who believe the same.
