3 Maccabees 3:21

Accordingly, bearing no ill will against their kinsmen, but rather remembering our connection with them, and the numerous matters with sincere heart from a remote period entrusted to them, we wished to venture a total alteration of their state, by giving them the rights of citizens of Alexandria, and to admit them to the everlasting rites of our solemnities.

Apostolic Fathers

1 Clement 2:1

Moreover, ye were all distinguished by humility, and were in no respect puffed up with pride, but yielded obedience rather than extorted it, and were more willing to give than to receive. Content with the provision which God had made for you, and carefully attending to His words, ye were inwardly filled with His doctrine, and His sufferings were before your eyes. Thus a profound and abundant peace was given to you all, and ye had an insatiable desire for doing good, while a full outpouring of the Holy Spirit was upon you all. Full of holy designs, ye did, with true earnestness of mind and a godly confidence, stretch forth your hands to God Almighty, beseeching Him to be merciful unto you, if ye had been guilty of any involuntary transgression. Day and night ye were anxious for the whole brotherhood, that the number of Gods elect might be saved with mercy and a good conscience. Ye were sincere and uncorrupted, and forgetful of injuries between one another. Every kind of faction and schism was abominable in your sight. Ye mourned over the transgressions of your neighbours: their deficiencies you deemed your own. Ye never grudged any act of kindness, beingready to every good work.” Adorned by a thoroughly virtuous and religious life, ye did all things in the fear of God. The commandments and ordinances of the Lord were written upon the tablets of your hearts.

1 Clement 21:1

Take heed, beloved, lest His many kindnesses lead to the condemnation of us all. [For thus it must be] unless we walk worthy of Him, and with one mind do those things which are good and well-pleasing in His sight. For [the Scripture] saith in a certain place, “The Spirit of the Lord is a candle searching the secret parts of the belly.” Let us reflect how near He is, and that none of the thoughts or reasonings in which we engage are hid from Him. It is right, therefore, that we should not leave the post which His will has assigned us. Let us rather offend those men who are foolish, and inconsiderate, and lifted up, and who glory in the pride of their speech, than [offend] God. Let us reverence the Lord Jesus Christ, whose blood was given for us; let us esteem those who have the rule over us; let us honour the aged among us; let us train up the young men in the fear of God; let us direct our wives to that which is good. Let them exhibit the lovely habit of purity [in all their conduct]; let them show forth the sincere disposition of meekness; let them make manifest the command which they have of their tongue, by their manner of speaking; let them display their love, not by preferring one to another, but by showing equal affection to all that piously fear God. Let your children be partakers of true Christian training; let them learn of how great avail humility is with Godhow much the spirit of pure affection can prevail with Himhow excellent and great His fear is, and how it, saves all those who walk in it with a pure mind. For He is a Searcher of the thoughts and desires [of the heart]: His breath is in us; and when He pleases, He will take it away.

2 Clement 9:1

And let no one of you say that this very flesh shall not be judged, nor rise again. Consider ye in what [state] ye were saved, in what ye received sight, if not while ye were in this flesh. We must therefore preserve the flesh as the temple of God. For as ye were called in the flesh, ye shall also come [to be judged] in the flesh. As Christ the Lord who saved us, though He was first a Spirit, became flesh, and thus called us, so shall we also receive the reward in this flesh. Let us therefore love one another, that we may all attain to the kingdom of God. While we have an opportunity of being healed, let us yield ourselves to God that healeth us, and give to Him a recompense. Of what sort? Repentance out of a sincere heart; for He knows all things beforehand, and is acquainted with what is in our hearts. Let us therefore give Him praise, not with the mouth only, but also with the heart, that He may accept us as sons. For the Lord has said, “Those are my brethren who do the will of my Father.”
