Catechetical Lectures 18:6
A felled tree will bloom again; will not fallen man bloom again? What was sown and reaped sits in the barnyard; will not man, once cut off from this world, sit in the barnyard? The branches of vines and trees, when completely cut off, receive life and bear fruit if grafted on; will not man, for whom plants exist, resurrect after being buried? Comparatively speaking, which task is the greater: creating a statue or that did not exist before , or remaking one that was broken, using the same form? Cannot God who made us out of nothing make those who lived and are now dead rise again? …. Those things that were created for us come back to life once dead; will not we, for whom they live, rise again once dead?
