Celestial Hierarchies - Chapter IX
Of the Principalities, Archangels and Angels, and of their last Hierarchy.
...The name of the Celestial Principalities signifies their Godlike princeliness and authoritativeness in an Order which is holy and most fitting to the princely Powers, and that they are wholly turned towards the Prince of Princes, and lead others in princely fashion, and that they are formed, as far as possible, in the likeness of the Source of Principality, and reveal Its super-essential order by the good Order of the princely Powers.
...The holy Order of Archangels, through its middle position, participates in the two extremes, being joined with the most holy Principalities and with the holy Angels.
It is joined with the Princedoms because it is turned in a princely way to the super-essential Principality and, as far as it can attain, moulds itself in His likeness, and it is seen to be the cause of the union of the Angels with its own orderly and invisible leadership. It is joined with the Angels because it belongs to the interpreting Order, receiving in its turn the illuminations from the First Powers, and beneficently announcing these revelations to the Angels; and by means of the Angels it shows them forth to us in the measure of the mystical receptivity of each one who is inspired by the divine Illumination. For the Angels, as we have said, fill up and complete the lowest choir of all the Hierarchies of the Celestial Intelligences since they are the last of the Celestial Beings possessing the angelic nature. ...their choir is more directly in contact With manifested and mundane things.
The highest Order, as we have said, being in the foremost place near the Hidden One, must be regarded as hierarchically ordering in a bidden manner the second Order; and the second Order of Dominions, Virtues and Powers, leads the Principalities, Archangels and Angels more manifestly, indeed, than the first Hierarchy, but in a more hidden manner than the Order below it; and the revealing Order of the Principalities, Archangels and Angels presides one through the other over the human hierarchies so that their elevation and turning to God and their communion and union with Him may be in order; and moreover, that the procession from God, beneficently granted to all the Hierarchies, and visiting them all in common, may be with the most holy order.
