..he pretends that there are two prinicples, which doctrine we judge to be false and heretical because, as Moses testifies, God created heaven and earth not in several but in one prinicple.
Now, PB was talking about Manichaeans, but the observation applies eminiently to the philosophy of origins. He was right, Moses in scripture conveys a unitry principle of and in creation: God's speaking in wisdom and love producing one entire creation de novo: no room for alternative principles, such as idealism, materialism or naturo-mysticism. When attempts are made to mix the unified creation with materialism, we get an attempt at two principles going at once: incoherent, crazy and undoing Christ, who is the creator!
I have to wonder at people like our esteemed Archbishop, who think that the notion of the two mixing is somehow rational! Of course Christ diluted is Christ eliminated. Not Good Peter!
