The author considers Jesus' resurrection in relation to his offices as Messiah: prophet, priest (Hebrews 5:5–10), and king (Acts 2:30–32). He wants to emphasize that the resurrection on Sunday is more than just a "proof" of the gospel of the cross.
What is the church? The author wants to reflect on what he calls the "essence of the church," by which he means something more than just the functions of the church.
