...of the Greek Variety

Saint Gregory of Nazianzus:

'Through visible objects is made apparent the ordering of nature whereby reason is able to deduce the Author of the universe. How indeed could the universe have begun to exist, and how could it be still in existence, if God had not given it existence and were not sustaining it day by day now?'

Comment: All that exists must either have come into existence or have been present from all eternity. Nothing is able to cause its own existence, it cannot simply will itself into being. For it to will itself into being, it would have to already exist, which is absurd.
