Bede, on Jude 1:6

“And the angels who kept not their principality, but forsook their own habitation, he hath reserved under darkness in everlasting chains, unto the judgment of the great day.”

“The angels, indeed, who did not keep their own position, etc. And in this sentence, as in the previous one, we must first remember that Jesus our Lord punished the transgressing angels. For He, the man born at the end of the ages from a Virgin, who received the name Jesus by the angel's declaration, being God born from the Father before all ages, arranged every creature with the Father as He willed, and from the beginning condemned the haughty angels under the darkness of this air, reserving them for greater punishment on the day of judgment. And therefore, rightly are they to be condemned who contend that Christ Jesus was not true God, but only a man, and born of both genders. Furthermore, it must be inferred that He who did not spare the sinning angels will not spare haughty men either; but those who did not keep their position, namely, by the grace of adoption made sons of God, but forsook their abode, that is, the unity of the Church, in which they were reborn unto God, or certainly the seats of the heavenly kingdom which they would have received if they kept the faith, He will also condemn severely before the judgment and more severely in the universal judgment.”
