Section 1
On the Celestial Hierarchy · Pseudo-Dionysius the Areopagite
It is necessary then, as I think, first to set forth what we think is the purpose of every Hierarchy, and what benefit each one confers upon its followers; and next to celebrate the Heavenly Hierarchies according to their revelation in the Oracles; then following these Oracles, to say in what sacred forms the holy writings of the Oracles depict the celestial orders, and to what sort of simplicity we must be carried through the representations; in order that we also may not, like the vulgar, irreverently think that the heavenly and Godlike minds are certain many-footed and many-faced creatures, or moulded to the brutishness of oxen , or the savage form of lions , and fashioned like the hooked beaks of eagles , or the feathery down of birds , and should imagine that there are certain wheels of fire above the heaven, or material thrones upon which the Godhead may recline, or certain many-coloured horses, and spear-bearing leaders of the host , and whatever else was transmitted by the Oracles to us under multifarious symbols of sacred imagery.
