In the Name of

Raymond Brown suggests that when Peter exhorts new believers to be baptized "in the name of Jesus Christ" (Acts 2:38), he is primarily referring to the confession that new believers would make at their baptism: e.g. "Jesus Christ is Lord" (cf. 1 Cor. 1:2, Phil. 2:11). This is an interesting speculation that would fit nicely with the credo (Apostles' Creed) in all the early liturgies that converts recited at their baptisms.
