Resurrection of the Dead from Catholic Apologetics
"By 'resurrection' Christians do not mean only the return to life in the body of a dead human being; it means taking on a completely new existence. We believe that the souls of all those who have died will be reunited to their bodies; but those bodies will have different characteristics.
We Catholic Christians profess this belief often when we pray the Apostles Creed: I believe in ... the resurrection of the body. In the Nicene Creed, we profess: We look for the resurrection of the dead. "
