Indeed, Christ’s resurrection was not simply a return to earthly life, like those whom he had raised from the dead during his public ministry: the daughter of Jairus, Lazarus and the young man of Naim. These facts were miraculous events (and therefore extraordinary), but these persons reacquired through the power of Jesus “ordinary” earthly life. At a later time they again died, as St. Augustine frequently observes.
In the case of Christ’s resurrection the situation was essentially different. In his risen body he passed from death to another life beyond time and space. This risen body of Jesus was filled with the power of the Holy Spirit and shared in the divine life of glory. So it can be said of Christ, in the words of St. Paul, that he is the “heavenly man” (cf. 1 Cor 15:47 f.).
