In metaphysics class we were discussing creation, and one student asked, "Why is creation EX NIHILO" ("from nothing," for those of you in Rio Linda) important? Couldn't the creation have been made from pre-existent matter? I know that Origen believed that God created from pre-existent matter, but I also know that Origen was later declared a heretic. As we got to discussing, several things seemed apparent to me: If God created with pre-existent matter... 1) If matter were pre-existent, it would have to be co-eternal with God. 2) This matter must be indestructible. God must not be able to tamper with matter, only move it, if this is true. 3) This suggests a Platonic type of dualism. 4) Does this mean that God could not create spirit beings, since spirit would not be a part of that pre-existent matter? What do you guys think? I may decide to write a paper on this, if I can get enough ideas going... So I guess the question is, why is creation EX NIHILO important?
