In my own church background and circles the historic emphasis has been on the Lord's Supper as a memorial. As Smith rightly points out, the Lord's Supper is indeed a memorial, but it is not just a memorial. This realization makes the Table even more meaningful and personal.
Smith does not separate the Supper from the Word or the working of the Holy Spirit. It is the Word that gives us the context and informs us of the meaning and purpose of the Supper. It is the Holy Spirit that makes the meaning and purpose of the Supper real to us in our corporate church life as well as in the individual lives of each believer participating. The author also understands there is a certain mystery to the Lord's Supper that our intellect will not fully comprehend, but it is also that same intellect that informs our humble obedience in observing the Supper.
The reader may come across a statement or two in this book that could cause the eyebrows to raise in question or disagreement. Dr. Smith's own view of the Lord's Supper has roots that go back through John Calvin, and as such reflects an overall view of the Table that I am personally sympathetic to. Whatever few statements raised my eyebrows were far out weighed by the positive contribution Dr. Smith has made to the church's understanding of the Lord's Supper.
If you are sensing that there is more to the Lord's Supper then your tradition's peculiar emphasis; that perhaps there is something about the meaning and purpose of the Lord's Supper that you are missing, this will be a helpful book to read.
