Pius XI (1925)
 Both Men and Angels are subject 
to the Kingship of Christ

[From the Encyclical Quas primas on the Kingship of Christ, December 11, 1925]

Moreover, on what foundation this dignity and power of our Lord rests, Cyril of Alexandria aptly observes: "He obtained his dominion over all creatures, to speak in a word, not by having wrested it by force or brought it in from some other source, but by His own essence and nature"; * naturally, His kingdom depends on that wonderful union which is called hypostatic. Therefore, it follows not only that Christ is to be adored as God by angels and men, but also that angels and men obey and are subject to His power as man, namely, that Christ obtains His power over all creatures solely in the name of the hypostatic union. ---But yet what could be more pleasing to us and more pleasant to contemplate than that Christ commands us not only by right of birth but also by an acquired right, that is, of redemption? Would that all forgetful men would recall what price they have cost our Savior, for, "not with corruptible things as with gold or silver were you redeemed but by the precious blood of Christ, as of a lamb unspotted and undefiled" [1 Pet. 1:18, 19]. Now we are not our own, since Christ has bought us "with a great price" [1 Cor. 5:20]; our very bodies "are members of Christ" [1 Cor. 6:15 ].   [D2194]
