Salvation is to be saved from some evil. The resurrection of Jesus reveals a particular salvation. The just in the bosom of Abraham possessed a natural bliss. Christ won for them supernatural bliss in heaven, however there is something deficient in this apart from the resurrection.
The just are in a radically deficient state. They are human souls without bodies. To possess supernatural bliss in this state is an amazing blessing for the just. Yet it remains deficient in so far as the just exist in this radically deficient way.
The resurrection reveals a salvation of the body. The just will enjoy supernatural bliss precisely as substantially human. It is a salvation from being perpetually in a deficient state, which is certainly an evil.
