"For all these things I gave thanks to the Lord, because He had pity on all that call upon His name; and sent the angel of repentance to us who sinned against Him, and renewed our spirit; and when we were already destroyed, and had no hope of life, He restored us to newness of life.”Hermas
The Shepherd Bk. 3 Pt. 3 Ch. XIV, Vol. 2

"“But I, the angel of repentance, say to you Fear not the devil; for I was sent,” says he, “to be with you who repent with all your heart, and to make you strong in faith. Trust God, then, ye who on account of your sins have despaired of life, and who add to your sins and weigh down your life; for if ye return to the Lord with all your heart, and practice righteousness the rest of your days, and serve Him according to His will, He will heal your former sins, and you will have power to hold sway over the works of the devil. But as to the threats of the devil, fear them not at all, for he is powerless as the sinews of a dead man."Hermas
The Shepherd Bk. 2 Pt. 2 Ch. III, Vol. 2

"So is he always pure for prayer. He also prays in the society of angels, as being already of angelic rank, and he is never out of their holy keeping; and though he prays alone, he has the choir of the saints standing with him."Clement
Stromata Bk. 7 Ch. XII, Vol 2

"And we know that in this way the angels are superior to men; so that men, when made perfect, become like the angels. “For in the resurrection they neither marry nor are given in marriage, but the righteous are as the angels in heaven,” (cf. Mat_22:30)"Origen
Against Celsus Bk. 4 Ch. XXIX, Vol. 4

"I grant that the apostles themselves make use of the angels they have as helpers in Order to fulfill the mission of their preaching and to complete the work of the gospel. For this is what was said in the Acts of the Apostles, that they that it was Peter's angel who knocked on the gate. [Act_12:13, 15] Similarly then there is understood to be both an angel Of Paul, just as there is of Peter, and another of another apostle, and of each One by ranking or for their merits, which assuredly consist in their labors and teaching, either of the apostles or of the rest of the teachers after them."Origen
Homilies on Numbers, Homily 11

Men, he says, “in the resurrection will be like the angels of God,” (Mat_22:30) to wit, in incorruption, and immortality, and incapacity of loss. For the incorruptible nature is not the subject of generation; it grows not, sleeps not, hungers not, thirsts not, is not wearied, suffers not, dies not, is not pierced by nails and spear, sweats not, drops not with blood. Of such kind are the natures of the angels and of souls released from the body. For both these are of another kind, and different from these creatures of our world, which are visible and perishing.Hippolytus
Fragments Ch II, Vol.V

"Put, therefore, ye who are empty and fickle in your faith, the Lord in your heart, and ye will know that there is nothing easier or sweeter, or more manageable, than these commandments. Return, ye who walk in the commandments of the devil, in hard, and bitter, and wild licentiousness, and fear not the devil; for there is no power in him against you, for I will be with you, the angel of repentance, who am lord over him. The devil has fear only, but his fear has no strength. (Jam_2:19, Jam_4:6, Jam_4:7) Fear him not, then, and he will flee from you.”Hermas
The Shepherd Bk. 2 Pt. 2 Ch. IV, Vol. 2

"Seeing them, therefore, so beaten and so badly used, I was grieved for them, because they were so tormented, and had no rest at all. And I said to the Shepherd who talked with me, “Sir, who is this shepherd, who is so pitiless and severe, and so completely devoid of compassion for these sheep?” “This,” he replied, “is the angel of punishment; and he belongs to the just angels, and is appointed to punish. He accordingly takes those who wander away from God, and who have walked in the desires and deceits of this world, and chastises them as they deserve with terrible and diverse punishments.” “I would know, sir,” I said, “Of what nature are these diverse tortures and punishments?” “Hear,” he said, “the various tortures and punishments. The tortures are such as occur during life. For some are punished with losses, others with want, others with sicknesses of various kinds, and others with all kinds of disorder and confusion; others are insulted by unworthy persons, and exposed to suffering in many other ways: for many, becoming unstable in their plans, try many things, and none of them at all succeed, and they say they are not prosperous in their undertakings; and it does not occur to their minds that they have done evil deeds, but they blame the Lord. When, therefore, they have been afflicted with all kinds of affliction, then are they delivered unto me for good training, and they are made strong in the faith of the Lord; and for the rest of the days of their life they are subject to the Lord with pure hearts, and are successful in all their undertakings, obtaining from the Lord everything they ask; and then they glorify the Lord, that they were delivered to me, and no longer suffer any evil.”"Hermas
The Shepherd Bk. 3 Pt. 1 Ch. III, Vol. 2

"A similar method must be followed in treating of the angels; nor are we to suppose that it is the result of accident that a particular office is assigned to a particular angel: as to Raphael, e.g., the work of curing and healing to Gabriel, the conduct of wars; to Michael, the duty of attending to the prayers and supplications of mortals. For we are not to imagine that they obtained these offices otherwise than by their own merits, and by the zeal and excellent qualities which they severally displayed before this world was formed; so that afterwards in the order of archangels, this or that office was assigned to each one, while others deserved to be enrolled in the order of angels, and to act under this or that archangel, or that leader or head of an order."Origen
De Principiis Bk. 1 Ch. VIII, Vol. 4

(Dan_9:21)“And, behold, the man Gabriel … flying.” You see how the prophet likens the speed of the angels to a winged bird, on account of the light and rapid motion with which these spirits fly so quickly in discharge of orders.Hippolytus
