Adopting for this verse 51 the reading of the Vatican manuscript, pantes sou koimêsometha, pantes de allagêsometha, I have been led to take a different view of this chapter. "The whole chapter is written on the theme of the resurrection of the just: the wicked are nowhere considered" (Notes on St Paul pp. 131 sq.; cf pp. 378, 381, on Romans viii, 21-39). It is St Paul's manner at times to prescind from the wicked, and treat of the destiny of the normal Christian; or, as St Thomas would put it, to tell us of what is per se, and omit what is per accidens. St Thomas himself, in this very chapter, takes 1 Cor. xv, 44, to refer only to the resurrection of the just. Elsewhere however, on the solemn occasion of his trial before Felix, St Paul bears witness to the resurrection of the wicked: Having hope in God that there is to be resurrection of the dead, both just and unjust (Acts xxiv, 15).
