Hebrews 7:21

But swear, says Justinus, if you wish to know “what eye hath not seen, and ear hath not heard, and the things which have not entered into the heart;” that is, if you wish to know Him who is good above all, Him who is more exalted, (swear) that you will preserve the secrets (of the Justinian) discipline, as intended to be kept silent. For also our Father, on beholding the Good One, and on being initiated with Him, preserved the mysteries respecting which silence is enjoined, and sware, as it has been written, “The Lord sware, and will not repent.” Having, then, in this way set the seal to these tenets, he seeks to inveigle (his followers) with more legends, (which are detailed) through a greater number of books; and so he conducts (his readers) to the Good One, consummating the initiated (by admitting them into) the unspeakable Mysteries. …

Hence also, in the first book inscribed “Baruch,” has been written the oath which they compel those to swear who are about to hear these mysteries, and be initiated with the Good One. And this oath, (Justinus) says, our Father Elohim sware when He was beside the Good One, and having sworn He did not repent (of the oath), respecting which, he says, it has been written, “The Lord sware, and will not repent.” Now the oath is couched in these terms: “I swear by that Good One who is above all, to guard these mysteries, and to divulge them to no one, and not to relapse from the Good One to the creature.” And when he has sworn this oath, he goes on to the Good One, and beholds “whatever things eye hath not seen, and ear hath not heard, and which have not entered into the heart of man;” and he drinks from life-giving water, which is to them, as they suppose, a bath, a fountain of life-giving, bu …

“And inasmuch as not without an oath.” What is “And inasmuch as not without an oath”? That is, Behold another difference also. And these things were not merely promised (he says). “For those priests were made without an oath,” ( ver. 21, 22 ) “but This with an oath, by Him that said unto Him, The Lord swore and will not repent, Thou art Priest for ever after the order of Melchisedec. By so much was Jesus made a surety of a better covenant.” He lays down two points of difference, that it hath no end as the [covenant] of the Law had; and this he proves from [its being] Christ who exercises [the priesthood]; for he says “according to the power of an endless life.” And he proves it also from the oath, because “He swore,” &c., and from the fact; for if the other was cast out, because it was weak, this stands firm, because it is powerful. He proves it also from the priest. …

He is named Christ from being as man anointed with the Holy Ghost, and called our High Priest, Apostle, Prophet and King. Long ago the divine Moses exclaimed “The Lord thy God will raise up unto thee a prophet, from the midst of thee, of thy brethren, like unto me.” And the divine David cries “The Lord hath sworn and will not repent, Thou art a priest forever after the order of Melchisedek.” This prophecy is confirmed by the divine Apostle. And again “seeing then that we have a great High Priest that has passed into the heavens, Jesus the Son of God, let us hold fast our profession.”

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 . …
