6. The hierarchical picture of the angels, informs us that several orders of those beings are charged, in virtue of their attributes, with the government of the physical universe and of the human race, and that they were created for the purpose of doing this work. But, according to the Book of Genesis, the material world and the human race have only been in existence for six thousand years; what then, did the angels do before that epoch, through the eternity of the Past, seeing that the object for which they were created was not in existence? Have the angels existed from all eternity? It is to be supposed so, since we are assured by the Church that they serve for the glorification of the Almighty; for, if they were created at any given epoch in the past, God must have remained, previously to that epoch – that is to say, throughout an eternity – without worshippers.
