Though I found this a very engaging work, it was not persuasive. In fact, it seems to me to be a case study in misleading argumentation. The "word study" on the meaning of baptism makes several missteps, such as appealing to remote contexts in order to control what must be meant in an immediate context, imputing to the baptist view a false assumption about technical meaning, selective use of the evidence, and so on.
The dialogue gets stuck on the importance of "burial" to the symbolism of baptism, and in doing so misses the point of the baptist position. Allow me to cite one contemporary Baptist scholar.
“It may be objected that many were buried above the ground in caves during the NT era, and hence the notion of burial underground as pictured in baptism does not clearly portray death. The objection helps us to clarify the Pauline intention, but it does not succeed in terms of its main point. In saying that baptism pictures death and resurrection, the point is not that death is always underground. Baptist pictures death because submersion under water kills. The waters represent the flood of God’s judgment on account of sin (see 1 Pet 3:20-21), and hence even Jesus himself, as Mark 10:38-39 explains, underwent a baptism in which he absorbed God’s wrath on the cross for the sake of his people. Submersion under the water in baptism – which is in Jesus’ name – indicates that the persons baptized have experienced God’s judgment in Christ. That is, since they are incorporated in Christ, he has borne the judgment they deserved. Submersion under the water, then, does not specify that the dead are buried underground. The picture is not meant to be taken so literally. It does communicate, however, death and burial. Submersion is an apt picture because it demonstrates that death overwhelms and conquers its subjects. Pouring and sprinkling simply do not have the same effect….Similarly, newness of life is represented by emerging from the water. Believers now enjoy the resurrection life of Christ because they have been incorporated into him (Rom 6:4). I conclude, then, that the imagery used in Col 2:12 and Rom 6:3-5 points to immersion (“going into”) and emersion (“coming out of”)." (Thomas R. Schreiner, Believer's Baptism, 82)
Without belaboring the point, let me just conclude that this is an intriguing book, but certainly not a convincing one. I would encourage readers to study the issue much more broadly than this book. On a positive note, I believe the book can help baptists to understand how others perceive their arguments, and to clarify them accordingly.
