Romans 3:4

7. Nor ought it, my dearest brother, to disturb any one who is faithful and mindful of the Gospel, and retains the commands of the apostle who forewarns us; if in the last days certain persons, proud, contumacious, and enemies of God’s priests, either depart from the Church or act against the Church, since both the Lord and His apostles have previously foretold that there should be such. Nor let any one wonder that the servant placed over them should be forsaken by some, when His own disciples forsook the Lord Himself, who performed such great and wonderful works, and illustrated the attributes of God the Father by the testimony of His doings. …

8. Yet although, in these last times, evangelic rigour has not so failed in the Church of God, nor the strength of Christian virtue or faith so languished, that there is not left a portion of the priests which in no respect gives way under these ruins of things and wrecks of faith; but, bold and stedfast, they maintain the honour of the divine majesty and the priestly dignity, with full observance of fear. We remember and keep in view that, although others succumbed and yielded, Mattathias boldly vindicated God’s law; that Elias, when the Jews gave way and departed from the divine religion, stood and nobly contended; that Daniel, deterred neither by the loneliness of a foreign country nor by the harassment of continual persecution, frequently and gloriously suffered martyrdoms; also that the three youths, subdued neither by their tender years nor by threats, stood up faithfully against t …

8. You have written also, that on my account the Church has now a portion of herself in a state of dispersion, although the whole people of the Church are collected, and united, and joined to itself in an undivided concord: they alone have remained without, who even, if they had been within, would have had to be cast out. Nor does the Lord, the protector of His people, and their guardian, suffer the wheat to be snatched from His floor; but the chaff alone can be separated from the Church, since also the apostle says, “For what if some of them have departed from the faith? shall their unbelief make the faith of God of none effect? God forbid; for God is true, but every man a liar.” And the Lord also in the Gospel, when disciples forsook Him as He spoke, turning to the twelve, said, “Will ye also go away?” then Peter answered Him, “Lord, to whom shall we go? Thou hast the word of eternal l …

Paulus of Obba said: It does not disturb me if any man does not assert the faith and truth of the Church, since the apostle says, “For what if some of them have fallen away from the faith? Has their unbelief made the faith of God of no effect? By no means. For God is true, but every man a liar.” But if God is true, how can the truth of baptism be among the heretics, among whom God is not?

38. I would also say, O Lord my God, what the following Scripture reminds me of; yea, I will say it without fear. For I will speak the truth, Thou inspiring me as to what Thou willest that I should say out of these words. For by none other than Thy inspiration do I believe that I can speak the truth, since Thou art the Truth, but every man a liar. And therefore he that “speaketh a lie, he speaketh of his own;” therefore that I may speak the truth, I will speak of Thine. Behold, Thou hast given unto us for food “every herb bearing seed,” which is upon the face of all the earth, “and every tree in the which is the fruit of a tree yielding seed.” Nor to us only, but to all the fowls of the air, and to the beasts of the earth, and to all creeping things; but unto the fishes, and great whales, Thou hast not given these things. …

Chapter 11. 20. Paul of Bobba said: "I for my part am not moved if some fail to uphold the faith and truth of the Church, seeing that the apostle says ‘For what if some did not believe? shall their unbelief make the faith of God without effect? God forbid: yea let God be true, but every man a liar.’ But if God be true, how can the truth of baptism be in the company of heretics, where God is not?"

6. Consider again. What does he say? Hath Christ spoken falsely? Where, I ask thee? “Where He says, ‘I go not up to the feast day;’ and went up.” For my part, I should wish thoroughly to examine this place, if so be we may see that Christ did not speak falsely. Yea rather, seeing that I have no doubt that Christ did not speak falsely, I will either thoroughly examine this passage and understand it, or, not understanding it, I will defer it. Yet that Christ spoke falsely will I never say. Grant that I have not understood it; I will depart in my ignorance. For better is it with piety to be ignorant, than with madness to pronounce judgment. Notwithstanding we are trying to examine, if so be by His assistance, who is the Truth, we may find something, and be found something ourselves, and this something will not be in the Truth a lie. …

1. Ye remember that the Apostle Peter, the first of all the Apostles, was disturbed at the Lord’s Passion. Of his own self disturbed, but by Christ renewed. For he was first a bold presumer, and became afterwards a timid denier. He had promised that he would die for the Lord, when the Lord was first to die for him. When he said then, “I will be with Thee even unto death,” and “I will lay down my life for Thee;” the Lord answered him, “Wilt thou lay down thy life for Me? Verily I say unto thee, Before the cock crow, thou shalt deny Me thrice.” They came to the hour; and because that Christ was God, and Peter a man, the Scripture was fulfilled, “I said in my panic, Every man is a liar.” And the Apostle says, “For God is true, and every man a liar.” Christ true, Peter a liar.

3. Tell me, O my Lord, what to say to Thy servants, my fellow-servants. The Apostle Thomas had Thee before him in order to ask Thee questions, and yet could not understand Thee unless he had Thee within him; I ask Thee because I know that Thou art over me; and I ask, seeking, as far as I can, to let my soul diffuse itself in that same region over me where I may listen to Thee, who usest no external sound to convey Thy teaching. Tell me, I pray, how it is that Thou goest to Thyself. …

6. For see what He saith; “If we say that we have no sin, we deceive ourselves, and the truth is not in us.” Consequently, if thou hast confessed thyself a sinner, the truth is in thee: for the Truth itself is light. Thy life hath not yet shone in perfect brightness, because there are sins in thee; but yet thou hast already begun to be enlightened, because there is in thee the confession of sins. For see what follows: “If we confess our sins, He is faithful and just to forgive us our sins, and to purge us from all iniquity.” Not only the past, but haply if we have contracted any from this life; because a man, so long as he bears the flesh, cannot but have some at any rate light sins. But these which we call light, do not thou make light of. If thou make light of them when thou weighest them, be afraid when thou countest them. …

2. The Psalm, then, beginneth thus: “O God, be not silent as to my praise; for the mouth of the ungodly, yea, the mouth of the deceitful is opened upon me” ( ver. 1 ). Whence it appeareth, both that the blame, which the ungodly and the deceitful is not silent of, is false, and that the praise, which God is not silent of, is true. “For God is true, but every man a liar;” for no man is true, except him in whom God speaketh. But the highest praise is that of the only-begotten Son of God, in which He is proclaimed even that which He is, the only-begotten Son of God. …

Ver. 4 . “God forbid.” The word ἐπιστεύθησαν , then, proclaims God’s gift.
