John F. MacArthur, Jr. was a United States Calvinistic evangelical writer and minister, noted for his radio program entitled Grace to You and as the editor of the Gold Medallion Book Award-winning MacArthur Study Bible. MacArthur was a fifth-generation pastor, a popular author and conference speaker, and served as pastor-teacher of Grace Community Church in Sun Valley, California beginning in 1969, as well as President of The Master’s College (and the related Master’s Seminary) in Santa Clarita, California.
This book combines four sermons MacArthur preached on the Lord's Supper from Matthew 26:17-30 and 1 Corinthians 11:17-34. These are not sermon transcripts, but more extensive outlines. There is some overlap between the sermons. Overall, it's a helpful study. He didn't get into some issues surrounding the supper, and he probably addressed some we don't hear frequently. I differ with some of his interpretive conclusions and also in some of the underlying theological assumptions. It is certainly worth having if you are studying those passages, or the Lord's Supper more generally.
