Aponius : Rising again with the same flesh as that with which he was buried, [Christ] stands behind the wall of our unbelief, the wall that as we sinned we built with our muddy, dirty works. About these works God spoke through the prophet Isaiah, "But your sins have made a wall between you and God." Behind the wall stands Christ the Lord, and he waits to be called on by the ungodly, and he summons the sinful soul to penitence. Behind the wall where [Christ] stands, he waits for the unbelieving to believe in him until such time as they reach baptism or penitence. — EXPOSITION OF SONG OF SONGS 4:16 Cyprian : Let us consider our sins, and reviewing the secrets of our action and mind, let us weigh the merits of our conscience. — Treatise III. On the Lapsed 21 Cyprian : The Lord can prohibit adversities, but the merits of sinners cause him to give no aid.… Therefore, let your sins and offences be numbered; let the wounds of your conscience be considered; and let each one cease to complain about God and about us, if he understands that he deserves what he suffers. — Treatise V. An Address to Demetrianus 11 Cyril of Alexandria : Scripture is accustomed to call hatred "toil." For the word has more than one meaning. Hatred wastes and withers up the hearts of those who receive it. Thus says the psalmist about someone or about Israel as a whole, "He conceived toil and bore iniquity." — COMMENTARY ON Isaiah 5:4.59:4-5 Fulgentius of Ruspe : Therefore, since bodies that cannot exist without a place cannot be spatially separated from God, without a doubt neither are the spirits that God created spatially separated from God.For every spirit that God created exists in some place, and God is there. [God], through the grace by means of which he grants to whom he wishes a holy and blessed life, is not in evil spirits; still he is always in all his creatures through his natural power. Thus there is no creature than can be found in whom God is not present through his power. Therefore, that nature can be separated from God that was or is able to be subject to sin. There is no other thing that can go away from God except that substance that is able or has been able to sin with its own will. For Isaiah says, "See, the Lord's hand is not too short to save or his ear too dull to hear. Rather, your iniquities have been barriers between you and your God." — BOOK TO VICTOR AGAINST THE SERMON OF FASTIDIOSUS THE ARIAN 4:1-2 Isaac of Nineveh : But since we say that God is plenteous in mercy, why is it that when amidst temptations we unceasingly knock and pray, we are not heard and He disregards our prayer? This we are clearly taught by the Prophet when he says, "The Lord's hand is not little, that it cannot save; nor is He hard of hearing, that He cannot hear: but our sins have separated us from Him." … Remember God at all times, and He will remember you whenever you fall into evils. — ASCETICAL HOMILIES 5 John Chrysostom : What the middle wall of partition is, he interprets by saying, "the enmity having abolished in His flesh, even the law of commandments contained in ordinances." Some indeed affirm that he means the wall of the Jews against the Greeks, because it did not allow the Jews to hold intercourse with the Greeks. To me, however, this does not seem to be the meaning, but rather that he calls "the enmity in the flesh," a middle wall, in that it is a common barrier, cutting us off alike from God. As the Prophet says, "Your iniquities separate between you and Me;" for that enmity which He had both against Jews and Gentiles was, as it were, a middle wall. And this, whilst the law existed, was not only not abolished, but rather was strengthened; "for the law," saith the Apostle, "worketh wrath." — HOMILIES ON Ephesians 5 John Chrysostom : It is the greatest punishment to commit sin, though we may remain unpunished; as on the other hand, it is the greatest honour and repose to live virtuously, though we may be punished. For sins separate us from God; as He Himself speaks; "Have not your sins separated between you and Me?" But punishments lead us back to God. As one saith, "Give peace; for Thou hast recompensed us for all things." Suppose any one hath a wound; which is the most deserving of fear, gangrene, or the surgeon's knife? the steel, or the devouring progress of the ulcer? Sin is a gangrene, punishment is the surgeon's knife. As then, he who hath a gangrene, although he is not lanced, hath to sustain the malady, and is then in the worse condition, when he is not lanced; so also the sinner, though he be not punished, is the most wretched of men; and is then especially wretched, when he hath no punishment, and is suffering no distress. — HOMILIES CONCERNING THE STATUES 6:14 John Chrysostom : For He Himself never turns away from us, but it is we who put ourselves far off: for "I am a God" we read "at hand and not a God afar off." And again, when He was rebuking them by the mouth of this prophet He said "Do not your sins separate between you and me?" Inasmuch then as this is the cause which puts us far from God, let us remove this obnoxious barrier, which prevents any near approach being made. But now hear how this has actually occurred in real instances. Amongst the Corinthians some man of mark committed a sin such as was not named even among the Gentiles. This man was a believer and belonged to the household of Christ; and some say that he was actually a member of the priesthood. What then? Did Paul cut him off from the communion of those who were in the way of salvation. By no means: for he himself it is who rebukes the Corinthians countless times, backwards and forwards, because they did not bring the man to a state of repentance: but, desiring to prove to us that there is no sin which cannot be healed, he said again concerning the man who had transgressed more grievously than the Gentiles: "Deliver such an one to Satan for destruction of the flesh that his spirit may be saved in the day of the Lord Jesus Christ." — LETTER TO THE FALLEN THEODORE 1:8
