Mk. 8:34-9:1
If you wish to be the Lord's disciple, it is necessary you "take your cross, and follow the Lord: " (Mk. 8:34) your cross; that is, your own straits and tortures, or your body only, which is after the manner of a cross. - Tertullian, On Idolatry, 12
When they came voluntarily to the Capitol,-when they freely approached to the obedience of the terrible wickedness,-did not their tread falter? Did not their sight darken, their heart tremble, their arms fall helplessly down? Did not their senses fail, their tongue cleave to their mouth, their speech grow weak? Could the servant of God stand there, and speak and renounce Christ, when he had already renounced the devil and the world? Was not that altar, whither he drew near to perish, to him a funeral pile? Ought he not to shudder at and flee from the devil's altar, which he had seen to smoke, and to be redolent of a foul rector, as if it were the funeral and sepulchre of his life? Why bring with you, O wretched man, a sacrifice? why immolate a victim? You yourself have come to the altar an offering; you yourself have come a victim: there you have immolated your salvation, your hope; there you have burnt up your faith in those deadly fires. - Saint Cyprian, On the Lapsed
But the discipline of all religion and truth is overturned, unless what is spiritually prescribed be faithfully observed; unless indeed any one should fear in the morning sacrifices, lest by the taste of wine he should be redolent of the blood of Christ. Therefore thus the brotherhood is beginning even to be kept back from the passion of Christ in persecutions, by learning in the offerings to be disturbed concerning His blood and His blood-shedding. Moreover, however, the Lord says in the Gospel, "Whosoever shall be ashamed of me, of him shall the Son of man be ashamed." (Mk. 8:38 ) And the apostle also speaks, saying, "If I pleased men, I should not be the servant of Christ." (Gal. 1:10) But how can we shed our blood for Christ, who blush to drink the blood of Christ? - Saint Cyprian, Epistle 62, 15

Mt 22:35-46
Saint John Chrysostom, Homily 71 on Matthew
For [God] sets before every race of mankind that which is always and universally just, as well as all righteousness; and every race knows that adultery, and fornication, and homicide, and such like, are sinful; and though they all commit such practices, yet they do not escape from the knowledge that they act unrighteously whenever they so do, with the exception of those who are possessed with an unclean spirit, and who have been debased by education, by wicked customs, and by sinful institutions, and who have lost, or rather quenched and put under, their natural ideas. For we may see that such persons are unwilling to submit to the same things which they inflict upon others, and reproach each other with hostile consciences for the acts which they perpetrate. And hence I think that our Lord and Saviour Jesus Christ spoke well when He summed up all righteousness and piety in two commandments. They are these: `Thou shalt love the Lord thy God with all thy heart, and with all thy strength, and thy neighbour as thyself.' (Matt. 22:37) For the man who loves God with all the heart, and with all the strength, being filled with a God-fearing mind, will reverence no other god; and since God wishes it, he would reverence that angel who is beloved by the same Lord and God. And the man who loves his neighbour as himself will wish for him the same good things that he wishes for himself, and no man will wish evil things for himself. Accordingly, he who loves his neighbour would pray and labour that his neighbour may be possessed of the same benefits as himself. Now nothing else is neighbour to man than that similarly-affectioned and reasonable being-man. Therefore, since all righteousness is divided into two branches, namely, in so far as it regards God and men, whoever, says the Scripture, loves the Lord God with all the heart, and all the strength, and his neighbour as himself, would be truly a righteous man. - Saint Justin the Philosopher, Dialogue With Trypho, 93
For when the Word of God, our Lord Jesus Christ, came unto all, and gathering alike the learned and unlearned, published to every sex and every age the precepts of salvation He made a large compendium of His precepts, that the memory of the scholars might not be burdened in the celestial learning, but might quickly learn what was necessary to a simple faith. Thus, when He taught what is life eternal, He embraced the sacrament of life in a large and divine brevity, saying, "And this is life eternal, that they might know Thee, the only and true God, and Jesus Christ, whom Thou hast sent." (Jn. 17:3) Also, when He would gather from the law and the prophets the first and greatest commandments, He said, "Hear, O Israel; the Lord thy God is one God: and thou shall love the Lord thy God with all thy heart, and with all thy mind, and with all thy strength. This is the first commandment. And the second is like unto it, Thou shalt love thy neighbour as thyself." (Matt. 12:29-31) "On these two commandments hang all the law and the prophets." (Matt. 22:40) And again: "Whatsoever good things ye would that men should do unto you, do ye even so to them. For this is the law and the prophets." (Matt. 7:12) - Saint Cyprian, On the Lord's Prayer, 28
There ought also to be no contentions and emulations among you, since the Lord left to us His peace, and it is written, "Thou shall love thy neighbour as thyself." (Lev. 19:18 ) "But if ye bite and find fault with one another, take heed that ye be not consumed one of another." (Matt. 22:39) From abuse and revilings also I entreat you to abstain, for "revilers do not attain the kingdom of God; " (Gal. 5:15) and the tongue which has confessed Christ should be preserved sound and pure with its honour. For he who, according to Christ's precept, speaks things peaceable and good and just, daily confesses Christ. We had renounced the world when we were baptized; but we have now indeed renounced the world when tried and approved by God, we leave all that we have, and have followed the Lord, and stand and live in His faith and fear. - Saint Cyprian, Epistle 6
For in the beginning of the world He gave to Adam himself and Eve a law, that they were not to eat of the fruit of the tree planted in the midst of paradise; but that, if they did contrariwise, by death they were to die. (Gen. 2:16-17; 3:2-3) Which law had continued enough for them, had it been kept. For in this law given to Adam we recognise in embryo all the precepts which afterwards sprouted forth when given through Moses; that is, Thou shalt love the Lord thy God from thy whole heart and out of thy whole soul; Thou shalt love thy neighbour as thyself; (Deut. 6:4-5; Lev. 19:18; cf Matt. 22:34-40; Mark 12:28-34; Lk. 10:25-28 ) Thou shalt not kill; Thou shall not commit adultery; Thou shalt not steal; False witness thou shall not utter; Honour thy father and mother; and, That which is another's, shall thou not covet. For the primordial law was given to Adam and Eve in paradise, as the womb of all the precepts of God. In short, if they had loved the Lord their God, they would not have contravened His precept; if they had habitually loved their neighbour-that is, themselves -they would not have believed the persuasion of the serpent, and thus would not have committed murder upon themselves, by falling from immortality, by contravening God's precept; from theft also they would have abstained, if they had not stealthily tasted of the fruit of the tree, nor had been anxious to skulk beneath a tree to escape the view of the Lord their God; nor would they have been made partners with the falsehood-asseverating devil, by believing him that they would be "like God; "and thus they would not have offended God either, as their Father, who had fashioned them from clay of the earth, as out of the womb of a mother; if they had not coveted another's, they would not have tasted of the unlawful fruit. - Tertullian, Adversus Judaeos, 2
For the chief points are faith towards God, hope towards Christ, the enjoyment of those good things for which we look, and love towards God and our neighbour. For, "Thou shall love the Lord thy God with all thy heart, and thy neighbour as thyself." (Deut. 6:5) And the Lord says, "This is life eternal, to know the only true God, and Jesus Christ whom He has sent." (Jn. 17:31) And again, "A new commandment give I unto you, that ye love one another. On these two commandments hang all the law and the prophets." (Jn. 13:34; Matt. 22:40) - Pseudo-Ignatius, Epistle to the Smyrneans, 6
Behold again: Jesus who was manifested, both by type and in the flesh, (cf 1 Tim. 3:16) is not the Son of man, but the Son of God. Since, therefore, they were to say that Christ was the son of David, fearing and understanding the error of the wicked, he saith, "The Lord said unto my Lord, Sit at My right hand, until I make Thine enemies Thy footstool." (Ps. 110:1; Matt. 22:43-45) And again, thus saith Isaiah, "The Lord said to Christ, my Lord, whose right hand I have holden, that the nations should yield obedience before Him; and I will break in pieces the strength of kings." (Is. 45:1) Behold how David calleth Him Lord and the Son of God. - Epistle of (Pseudo-)Barnabas, 12

Saint John Chrysostom, Commentary on Galatians, Chapter 2
Now the works of Satan are all sin, which also thou must renounce;—just as one who has escaped a tyrant has surely escaped his weapons also. All sin therefore, of every kind, is included in the works of the devil. Only know this; that all that thou sayest, especially at that most thrilling hour, is written in God’s books; when therefore thou doest any thing contrary to these promises, thou shalt be judged as a transgressor (cf Gal. 2:18 ). Thou renouncest therefore the works of Satan; I mean, all deeds and thoughts which are contrary to reason. - Saint Cyril of Jerusalem, Catechetical Lectures, 19, 5
I no longer wish to live after the manner of men, and my desire shall be fulfilled if ye consent. Be ye willing, then, that ye also may have your desires fulfilled. I entreat you in this brief letter; do ye give credit to me. Jesus Christ will reveal these things to you, [so that ye shall know] that I speak truly. He is the mouth altogether free from falsehood, by which the Father has truly spoken. Pray ye for me, that I may attain [the object of my desire]. I have not written to you according to the flesh, but according to the will of God. If I shall suffer, ye have wished [well] to me; but if I am rejected, ye have hated me. I no longer wish to live after the manner of men, and my desire shall be fulfilled if ye consent. "I am crucified with Christ: nevertheless I live; yet no longer I, since Christ liveth in me." (Gal. 2:20) - Pseudo-Ignatius, Epistle to the Romans, 8

Saint John Chrysostom, Homilies on Second Corinthians: (Homily 8) (Homily 9)
This Christ, when He was come, the Jews denied, but the devils confessed. But His forefather David was not ignorant of Him, when he said, I have ordained a lamp for mine Anointed (Ps. 132:17): which lamp some have interpreted to be the brightness of Prophecy (2 Pet. 1:19), others the flesh which He took upon Him from the Virgin, according to the Apostle’s word, But we have this treasure in earthen vessels (2 Cor. 4:7). The Prophet was not ignorant of Him, when He said, and announceth unto men His Christ (Amos 4:13). Moses also knew Him, Isaiah knew Him, and Jeremiah; not one of the Prophets was ignorant of Him. Even devils recognised Him, for He rebuked them, and the Scripture says, because they knew that He was Christ (Lk. 4:41). The Chief-priests knew Him not, and the devils confessed Him: the Chief Priests knew Him not, and a woman of Samaria proclaimed Him, saying, Come, see a man which told me all things that ever I did. Is not this the Christ (Jn. 4:29) - Saint Cyril of Jerusalem, Catechetical Lectures, 10
