I think this is a must read for educators. Slattery has an encyclopedic knowledge of the field. His citations alone provide a foundation for further scholarship and exploration.
The importance of a proleptic eschatology resonated with me. There are futuristic and apocalyptic eschatologies that are worried about some far off end time or heavenly reward. These are disconnected with the present. Then there are present focused theories that call into question the reality of a different existence. The myopia of these ideologies limit their usefulness. Proleptic eschatology, embraces a future redemption, but realizes that all times are connected on the quantum level.
As Donal Schon says, "Reality is messy" - color outside the lines.
