Hebrews 6:18

Further, Plato the philosopher says that the end is twofold: that which is communicable, and exists first in the ideal forms themselves, which he also calls “the good;” and that which partakes of it, and receives its likeness from it, as is the case in the men who appropriate virtue and true philosophy. Wherefore also Cleanthes, in the second book, On Pleasure , says that Socrates everywhere teaches that the just man and the happy are one and the same, and execrated the first man who separated the just from the useful, as having done an impious thing. For those are in truth impious who separate the useful from that which is right according to the law. Plato himself says that happiness ( εὐδαιμονία ) is to possess rightly the dæmon, and that the ruling faculty of the soul is called the dæmon; and he terms happiness ( εὐδαιμονία ) the most perfect and complete good. …

By the Prophets. Hearken to the words of Joel; “I will pour out My spirit upon all flesh, and your sons and your daughters shall prophesy, your old men shall dream dreams, your young men shall see visions,” ( Joel ii. 28 .) And hearken again to the words of Christ; “But ye shall receive power, when the Holy Ghost is come upon you, and ye shall be my witnesses both in Jerusalem, and in all Judea, and Samaria, and unto the uttermost part of the earth.” ( Acts i. 8 .) And truly, the Apostle means, He ought, as God, to have been believed; however, he does not ground his affirmation upon this, but examines it like a case where man is concerned, speaking much as he does in the Epistle to the Hebrews; ( Heb. vi. …

But wherefore said He not, that “He doeth nothing contrary,” instead of, “He cannot do”? It was that from this again He might show the invariableness and exactness of the Equality, for the expression imputes not weakness to Him, but even shows His great power; since in another place Paul saith of the Father, “That by two immutable things in which it was impos sible for God to lie” ( Heb. vi. 18 ): and again, “If we deny Him, He abideth faithful,” for “He cannot deny Himself.” ( 2 Tim. ii. 12, 13 .) And in truth this expression, “impossible,” is not declaratory of weakness, but power, power unspeakable. …

Ver. 18 . “That by two immutable things, in which it was impossible that God should lie.” What are these two? The speaking and promising; and the adding an oath to the promise. For since among men that which is [confirmed] by an oath is thought more worthy of credit, on this account He added that also. Seest thou that He regardeth not His own dignity, but how He may persuade men, and endures to have unworthy things said concerning Himself. That is He wishes to impart full assurance. And in the case of Abraham indeed [the Apostle] shows that the whole was of God, not of his patient endurance, since He was even willing to add an oath, for He by whom men swear, by Him also God “sware,” that is “by Himself.” They indeed as by one greater, but He not as by one greater. And yet He did it. For it is not the same thing for man to swear by himself, as for God. For man has no power over himself. …

Eran. We must believe without doubt in the promises given by the faithful witness, for, if we are wont to believe men who have promised to speak the truth even if they do not confirm their words with an oath, who can be so mad as to disbelieve the Creator of the Universe, when He adds an oath to his words? For He who forbids others to swear confirmed the immutability of his counsel by an oath, “that by two immutable things in which it was impossible for God to lie we might have a strong consolation who have fled for refuge to lay hold upon the hope set before us.”

Orth. Because each one of these proclaims the unchangeable and invariable character of God. For the impossibility of good becoming evil signifies the immensity of the goodness; and that He that is just should never become unjust, nor He that is true a liar, exhibits the stability and the strength that there is in truth and righteousness. Thus the true light could never become darkness; He that is could never become non existent, for the existence is perpetual and the light is naturally invariable. And so, after examining all other examples, you will find that the not being able is declaratory of the highest power. …

If therefore they accuse us for saying that God can do what He wishes, but that He wishes what is becoming to His own nature, and what is unbecoming He neither wishes nor is capable of; let them accuse too these saints and all the rest who maintain this position. Let them accuse even the Apostle who says “That by two immutable things in which it was impossible for God to lie.” And again “If we believe not, yet He abideth faithful: He cannot deny Himself.”

3. And what does this mean my brethren? For it is right for us to investigate the saying of the prophet, and especially on account of heretics who have turned their mind against the law. By Moses then, God gave commandment respecting sacrifices, and all the book called Leviticus is entirely taken up with the arrangement of these matters, so that He might accept the offerer. So through the Prophets, He blames him who despised these things, as disobedient to the command ment saying, ‘I have not required these at your hands. Neither did I speak to your fathers respecting sacrifices, nor command them concerning whole burnt-offerings.’ Now it is the opinion of some, that the Scriptures do not agree together, or that God, Who gave the commandment, is false. …

14. For that He is Jesus the Jews allow, but not further that He is Christ. Therefore saith the Apostle, Who is the liar, but he that denieth that Jesus is the Christ ? But Christ is a High Priest, whose priesthood passes not to another , neither having begun His Priesthood in time, nor having any successor in His High-Priesthood: as thou heardest on the Lord’s day, when we were discoursing in the congregation on the phrase, After the Order of Melchizedek . He received not the High-Priesthood from bodily succession, nor was He anointed with oil prepared by man, but before all ages by the Father; and He so far excels the others as with an oath He is made Priest: For they are priests without an oath, but He with an oath by Him that said, The Lord sware, and will not repent . …

180. From whence, then, Cicero and Panætius, or even Aristotle, got these ideas is perfectly clear. For though living before these two, Job had said: “I delivered the poor out of the hand of the strong, and I aided the fatherless for whom there was no helper. Let the blessing of him that was ready to perish come upon me.” Was not he most brave in that he bore so nobly the attacks of the devil, and overcame him with the powers of his mind? Nor have we cause to doubt the fortitude of him to whom the Lord said: “Gird up thy loins like a man. Put on loftiness and power. Humble every one that doeth wrong.” The Apostle also says: “Ye have a strong consolation.” He, then, is brave who finds consolation in any grief.
