ISB ~ 1 Corinthians 15 v4

he was buried:This important detail sets the Resurrection of Jesus over against his burial, indicating that his tomb was empty on Easter morning (Jn 20:1-10). The rising of Jesus from the grave is thus proclaimed as a physical and bodily event; it involved much more than the resuscitation of his corpse, but certainly nothing less than this. The Resurrection is a miracle of history that cannot be reduced to a metaphor for new life (CCC 639-40).

the Scriptures:Belief in a bodily resurrection can be traced back to the OT (CCC 652). • Several passages affirm that the Lord will raise the dead to live again (Is 26:19; Ezek 37:1-14; Dan 12:2; 2 Mac 7:9). Jesus was the first to benefit from these promises in advance of the messianic people united to him. For biblical background on the third day motif, See note on Lk 24:46.
