Dallas I has asked him if God can create beings with freewill who always choose right. So two of the authorities Peter cites believe it is possible all creatures commit moral evil - something they cannot believe if they thought some creatures really were wholly good. Another denies that God actually has created wholly good beings who freely choose good. So the very authorities Peter cites seem to deny the possibility of the creatures Peter claims exist. Peter's definition of angels also raises many questions.
Energy is physical.
Einstein said e equals mc squared. Energy is as physical as matter. Peter's analogy of spirit with abstract objects such as the number six is also confused. It has no capacity to think, no values and no will. Indeed the idea that the number six can be classified as evil or good, as Peter classifies angels, simply demonstrates that a better analogy is needed.
