Understanding Four Views on the Lord's Supper

This book served as a decent introduction to the debate on what Communion is and some of the practical implications of each view. Though I find myself aligned closest to the Reformed view, the Baptist and Catholic chapters were my favorites (the other two seemed to ramble). Beyond the debate on presence, both of these chapters really dove into the background and meaning of Communion in ways that I think are meaningful no matter what view you hold (such as the connections with Passover and other covenant signs, and the emphasis on the communal nature of the Lord's Table).

Whether this book is the best introduction to this topic is debatable (right now I have nothing else to compare it to), but it's definitely a topic with exploring for anyone who calls himself Christian.
