Peter Leithart has written an extremely succinct and helpful primer on baptism. I’m not sure what I think about his approach overall yet, but I certainly think he is moving in the right direction. I appreciate that he can handle the difficult passages on baptism and those indicating that some in the church will fall away. In the quote below, Leithart presents his approach to baptism texts, which I subscribe to:

First, we should takes the Bible’s statements about baptism as statements about baptism. Through Paul, God says that those who have been baptized are dead and buried with Christ (Romans 6:4) and that as many as have been baptized into Christ are clothed in Christ (Galatians 3:28-29). By analogy with the exodus, Paul implies that those who are baptized are rescued from Egypt and baptized into Christ, the new Moses (1 Corinthians 10:1-4). Peter tells his hearers at Pentecost to repent and be baptized “for the remission of your sins” (Acts 2:38) and says “baptism now saves you” (1 Peter 3:21). We can choose to disbelieve these things, or explain them away, but that’s what these texts say. I submit that we should believe what God has to say on the subject of baptism. That’s the starting point. When the Bible speaks about baptism, it is speaking about the rite of baptism; and what it says is true.
