Clement of Rome on Humility in 95CE

Let us therefore, brethren, be of humble mind, laying aside all haughtiness, and pride, and foolishness, and angry feelings; and let us act according to that which is written (for the Holy Spirit says, “Let not the wise man glory in his wisdom, neither let the mighty man glory in his might, neither let the rich man glory in his riches; but let him that glories glory in the Lord, in diligently seeking Him, and doing judgment and righteousness”), being especially mindful of the words of the Lord Jesus which He spoke, teaching us meekness and long-suffering.

For thus He spoke: “Be merciful, that you may obtain mercy; forgive, that it may be forgiven to you; as you do, so shall it be done unto you; as you judge, so shall you be judged; as you are kind, so shall kindness be shown to you; with what measure you use, with the same it shall be measured to you.” By this precept and by these rules let us establish ourselves, that we walk with all humility in obedience to His holy words. For the holy word says, “On whom shall I look, but on him that is meek and peaceable, and that trembles at My words?”

It is right and holy therefore, men and brethren, rather to obey God than to follow those who, through pride and sedition, have become the leaders of a detestable emulation. For we shall incur no slight injury, but rather great danger, if we rashly yield ourselves to the inclinations of men who aim at exciting strife and tumults, so as to draw us away from what is good. Let us be kind one to another after the pattern of the tender mercy and benignity of our Creator.

For it is written, “The kind-hearted shall inhabit the land, and the guiltless shall be left upon it, but transgressors shall be destroyed from off the face of it.” … Let us cleave, therefore, to those who cultivate peace with godliness, and not to those who hypocritically profess to desire it. For [the Scripture] says in a certain place, “This people honors Me with their lips, but their heart is far from Me.”

Athenagoras on True Christians in 175CE

Among us you will find uneducated persons, and artisans, and old women, who, if they are unable in words to prove the benefit of our doctrine, yet by their deeds exhibit the benefit arising from their persuasion of its truth: they do not rehearse speeches, but exhibit good works; when struck, they do not strike again; when robbed, they do not go to law; they give to those that ask of them, and love their neighbors as themselves.

Should we, then, unless we believed that a God presides over the human race, thus purge ourselves from evil? Most certainly not. But, because we are persuaded that we shall give an account of everything in the present life to God, who made us and the world, we adopt a temperate and benevolent and generally despised method of life, believing that we shall suffer no such great evil here, even should our lives be taken from us, compared with what we shall there receive for our meek and benevolent and moderate life from the great Judge. …

Who does not reckon among the things of greatest interest the contests of gladiators and wild beasts, especially those which are given by you? But we, deeming that to see a man put to death is much the same as killing him, have abjured such spectacles. How, then, when we do not even look on, lest we should contract guilt and pollution, can we put people to death?

And when we say that those women who use drugs to bring on abortion commit murder, and will have to give an account to God for the abortion, on what principle should we commit murder? For it does not belong to the same person to regard the very fetus in the womb as a created being, and therefore an object of God’s care, and when it has passed into life, to kill it; and not to expose an infant, because those who expose them are chargeable with child-murder, and on the other hand, when it has been reared to destroy it. But we are in all things always alike and the same, submitting ourselves to reason, and not ruling over it.

Clement of Alexandria on Walking as Jesus Walked in 195CE

“Putting away lying, every man speak truth with his neighbor: for we are members one of another. Let not the sun go down upon your wrath; neither give place to the devil. Let him that stole steal no more: but rather let him labor, working with his hands the thing which is good, that he may have something to give to him that is in need. Let all bitterness, and wrath, and anger, and clamor, and evil-speaking be put away from you, with all malice: and be kind one to another, tender-hearted, forgiving one another as God in Christ has forgiven you. Be therefore wise, followers of God, as dear children; and walk in love as Christ also has loved us. …

“If we live in the Spirit, let us walk in the Spirit. Let us not be desirous of vainglory, provoking one another, envying one another. Bear one another’s burdens, and so fulfill the law of Christ. Do not be deceived; God is not mocked. Let us not be weary in well-doing: for in due time we shall reap, if we do not faint.” …

And now, in truth, it is time for me to cease from my instruction, and for you to listen to the Teacher. … “And He is the propitiation for our sins,” as John says; Jesus, who heals both our body and soul—which are the proper man. “And not for our sins only, but also for the whole world. And by this we know that we know Him, if we keep His commandments. He that says, I know Him, and does not keep His commandments is a liar; and the truth is not in Him. But whoever keeps His word, in him truly is the love of God perfected. Here is how we know that we are in Him. He that says he abides in Him ought himself to walk even as He also walked.” 

Cyprian on Putting on the Armor of God in 250CE

For the secular contest men are trained and prepared, and reckon it a great glory of their honor if it should happen to them to be crowned in the sight of the people, and in the presence of the emperor. Behold a lofty and great contest, glorious also with the reward of a heavenly crown, inasmuch as God looks upon us as we struggle. … God looks upon us in the warfare, and fighting in the encounter of faith; His angels look on us, and Christ looks on us. How great is the dignity, and how great the happiness of the glory, to engage in the presence of God, and to be crowned, with Christ for a judge!

Let us be armed, beloved brethren, with our whole strength, and let us be prepared for the struggle with an uncorrupted mind, with a sound faith, with a devoted courage. Let the camp of God go forth to the battle-field which is appointed to us. … The Apostle Paul teaches us to be armed and prepared, saying, “We wrestle not against flesh and blood, but against powers, and the princes of this world and of this darkness, against spirits of wickedness in high places.

Therefore put on the whole armor, that you may be able to withstand in the most evil day, that when you have done everything you may stand; having your waist buckled about with truth, and having put on the breastplate of righteousness; and your feet shod with the preparation of the Gospel of peace; taking the shield of faith, with which you shall be able to quench all the fiery darts of the wicked one; and the helmet of salvation, and the sword of the Spirit, which is the word of God.”

Let us take these arms, let us fortify ourselves with these spiritual and heavenly safeguards, that in the most evil day we may be able to withstand, and to resist the threats of the devil: let us put on the breastplate of righteousness, that our breast may be fortified and safe against the darts of the enemy: let our feet be shod with evangelical teaching, and armed, so that when the serpent shall begin to be trampled and crushed by us, he may not be able to bite and trip us up: let us bravely bear the shield of faith, by the protection of which, whatever the enemy darts at us may be extinguished: let us take also for protection of our head the helmet of salvation, that our ears may be guarded from hearing the deadly edicts; that our eyes may be fortified, that they may not see the odious images; … that our mouth may be fortified, that the conquering tongue may confess Christ its Lord: let us also arm the right hand with the sword of the Spirit, that it may bravely reject the deadly sacrifices; that, mindful of the Eucharist, the hand which has received the Lord’s body may embrace the Lord Himself.
