The Studies of the New Testament and Its World series reflects a serious examination of the concerns and topics surrounding the first-century Christians and early Christian writings. In this series, the authors establish a firm foothold in early church studies with impactful research on such topics as Christian identity formation, the social background of the ancient world, Paul’s cosmology, and the early church’s use of baptism. Seminary students will find these scholarly and well-researched books challenging and thought-provoking, as will pastors and lay-persons interested in early Christianity.

Here, Dr. Hartman examines all New Testament passages which contain allusions to baptism. He discusses the variations and relative importance of these passages and includes a look at two documents from the Apostolic Fathers that shed further light on this subject for the early Christian. One of the particular motifs Hartman discovers is baptism’s relation to Christ. It is baptism into the name of the Lord Jesus that represents the fundamental reference point in this early Christian rite. It is this Name that gives baptism its significance and meaning.
