Catechism of the Catholic Church
True. Para. 996: . . . It is very commonly accepted that the life of the human person continues in a spiritual fashion after death. But how can we believe that this body, so clearly mortal, could rise to everlasting life?
Para. 997: . . . God, in his almighty power, will definitively grant incorruptible life to our bodies by reuniting them with our souls, through the power of Jesus' Resurrection.
