Enemies of Covenant Truth frequently and predictably distort the prophetic insights of historical church figures in incessant attempts to establish doctrinal credibility.
We may rest assured that Augustine’s understanding of “dispensation” bears no resemblance to what is posited in the declarations of today’s dispensationalism. We need look no further than the provided quotation itself to see that he recognized only two scriptural dispensations, the Old and the New: “…it is necessary to convince them that this exchange of the sacraments of the Old Testament for those of the New had been predicted by the voices of the prophets.” It is also an indictment of the dispensational claim that the OT prophets did not see what is averred to be the NT “parenthesis” of the church age. Augustine quite evidently and correctly believed that they did see it; that it is therefore no parenthesis; and that it is in reality the ultimate and consummate fulfillment of God’s intention to reserve unto Himself a sole and exclusive people from the foundation of the world.
Augustine was no dispensationalist.
I reject your conclusions as groundless on the face. But since you want to see more than just two dispensations, We can go the the very oldest Christian commentary on Bible prophecy (of any significant length) which has survived to the present day. This is found in the very famous work by Irenaeus, titled "Against Heresies," which is believed to have been written in 186 to 1 A.D.
Irenaeus taught the essence of dispensationalism in the following statements:
“Therefore the Son of the Father declares [Him] from the beginning, inasmuch as He was with the Father from the beginning, who did also show to the human race prophetic visions, and diversities of gifts, and His own ministrations, and the glory of the Father, in regular order and connection, at the fitting time for the benefit [of mankind]. For where there is a regular succession, there is also fixedness; and where fixedness, there suitability to the period; and where suitability, there also utility. And for this reason did the Word become the dispenser of the paternal grace for the benefit of men, for whom He made such great dispensations, revealing God indeed to men, but presenting man to God, and preserving at the same time the invisibility of the Father, lest man should at any time become a despiser of God, and that he should always possess something towards which he might advance; but, on the other hand, revealing God to men through many dispensations, lest man, failing away from God altogether, should cease to exist.” (Against Heresies, by Irenaeus, book IV, chapter XX, section 7.)
We need to notice certain key parts of this statement. Irenaeus said that God has “from the beginning” shown “to the human race prophetic visions” “in regular order and connection, at the fitting time,” and in “a regular succession,” with “suitability to the period.” And we particularly need to notice his statement that the Word was “revealing God to men through many dispensations.”
A few chapters later, Irenaeus further said, “There is one and the same God the Father, and His Word, who has been always present with the human race, by means indeed of various dispensations, and has wrought out many things, and saved from the beginning those who are saved, (for these are they who love God, and follow the Word of God according to the class to which they belong,) and has judged those who are judged, that is, those who forget God, and are blasphemous, and transgressors of His word.” (Against Heresies, by Irenaeus, book IV, chapter XXVIII, section 2.)
We already noticed in the first quotation we examined that Irenaeus said that “the Word” was “revealing God to men through many dispensations,” and that he said that this was done “at the fitting time,” in “a regular succession,” with “suitability to the period.” Now we see that he added that the Word “has been always present with the human race,” and saved various individuals “according to the class to which they belong.”
All of this was about past dispensations, but Irenaeus also spoke of future ones, saying, “Inasmuch, therefore, as the opinions of certain [orthodox persons] are derived from heretical discourses, they are both ignorant of God’s dispensations, and of the mystery of the resurrection of the just, and of the [earthly] kingdom which is the commencement of incorruption, by means of which kingdom those who shall be worthy are accustomed gradually to partake of the divine nature; and it is necessary to tell them respecting those things, that it behoves the righteous first to receive the promise of the inheritance which God promised to the fathers, and to reign in it, when they rise again to behold God in this creation which is renovated, and that the judgment should take place afterwards.” (Against Heresies, by Irenaeus, book V, chapter XXXII, section 1.)
In this short summary, I have included only a few statements that summarized his thoughts on the matter. But he spoke of these things many times, using the word dispensation, or its plural form dispensations, well over eighty times. He explicitly named a few of these dispensations, namely “the dispensation of the law,” (book III, chapter XI, section 7, and again in book III, chapter XV, section 3) which he also called “the Levitical Dispensation,” (book IV, Title of chapter XVII.) “the Mosaic dispensation,” (book IV, chapter XXXVI, section 2.) and “the legal dispensation.” (book III, chapter X, section 2 and the title of book V, chapter VIII.) He used this last term a third time, contrasting it with “the new dispensation of liberty” in book III, chapter X, section 4. And he spoke of the present age as “our dispensation” in book IV, chapter XV, section 2. Finally, he referred to “the future dispensation of the human race.” (book III, chapter XXII, section 3.) We should also note that he used the term the “dispensations of God,” eight times. These eight times were in book I, chapter X, section 1, book I, chapter XVI, section 3, book II, chapter XXV, section 3, book III, chapter XI, section 9, book IV, chapter XX, section 10, book IV, chapter XXI, section 3, book IV, chapter XXIII, section 1, and book IV, chapter XXXIII, section 1.
Irenaeus insisted that his doctrine of the dispensations was what the church had always taught, saying, ““The Church, though dispersed through our the whole world, even to the ends of the earth, has received from the apostles and their disciples this faith: [She believes] in one God, the Father Almighty, Maker of heaven, and earth, and the sea, and all things that are in them; and in one Christ Jesus, the Son of God, who became incarnate for our salvation; and in the Holy Spirit, who proclaimed through the prophets the dispensations of God, and the advents...” (Against Heresies, by Irenaeus, book I, chapter X, section 1.) He said again that “Where, therefore, the gifts of the Lord have been placed, there it behoves us to learn the truth, [namely,] from those who possess that succession of the Church which is from the apostles, and among whom exists that which is sound and blameless in conduct, as well as that which is unadulterated and incorrupt in speech. For these also preserve this faith of ours in one God who created all things; and they increase that love [which we have] for the Son of God, who accomplished such marvellous dispensations for our sake: and they expound the Scriptures to us without danger, neither blaspheming God, nor dishonouring the patriarchs, nor despising the prophets.” (Against Heresies, by Irenaeus, book IV, chapter XXVI, section 5.)
