For the most part, a very useful book. Mathison has done a lot of spade work to produce a faithful presentation of Calvin’s view of the Lord’s Supper. The first half is dedicated to how the ebb and flow of Protestants’ view of the Lord’s Supper for the last 500 years. The second half looks at the Biblical foundations for Calvin’s view in the Old and New Testaments, followed by critiques of Roman Catholic and Lutheran views. He ends by surveying some of the “sticky issues” associated (i.e. grape juice vs. wine, paedo-communion, and frequency). Helpful as a historical overview of the associated debates and views, and very useful in tackling how to properly frame and understand the sacrament.
