It is manifest from this passage, that the four Gospels, and the Acts of the Apostles (the parts of Scripture with which our concern principally lies), were acknowledged without dispute, even by those who raised objections, or entertained doubts, about some other parts of the same collection.  But the passage proves something more than this.  The author was extremely conversant in the writings of Christians which had been published from the commencement of the institution to his own time:  and it was from these writings that he drew his knowledge of the character and reception of the books in question.  That Eusebius recurred to this medium of information, and that he had examined with attention this species of proof, is shown, first, by a passage in the very chapter we are quoting, in which, speaking of the books which he calls spurious, “None,” he says, “of the ecclesiastical writers, in the succession of the apostles, have vouchsafed to make any mention of them in their writings;” and, secondly, by another passage of the same work, wherein, speaking of the First Epistle of Peter, “This,” he says, “the presbyters of ancient times have quoted in their writings as undoubtedly genuine;” (Lardner, vol. viii. p. 99.) and then, speaking of some other writings bearing the name of Peter, “We know,” he says, “that they have not been delivered down to us in the number of Catholic writings, forasmuch as no ecclesiastical writer of the ancients, or of our times, has made use of testimonies out of them.”  “But in the progress of this history,” the author proceeds, “we shall make it our business to show, together with the successions from the apostles, what ecclesiastical writers, in every age, have used such writings as these which are contradicted, and what they have said with regard to the Scriptures received in the New Testament, and acknowledged by all, and with regard to those which are not such.” (Lardner, vol. viii. p. 111)

After this it is reasonable to believe that when Eusebius states the four Gospels, and the Acts of the Apostles, as uncontradicted, uncontested, and acknowledged by all; and when he places them in opposition, not only to those which were spurious, in our sense of that term, but to those which were controverted, and even to those which were well known and approved by many, yet doubted of by some; he represents not only the sense of his own age, but the result of the evidence which the writings of prior ages, from the apostles’ time to his own, had furnished to his inquiries.  The opinion of Eusebius and his contemporaries appears to have been founded upon the testimony of writers whom they then called ancient:  and we may observe, that such of the works of these writers as have come down to our times entirely confirm the judgment, and support the distinction which Eusebius proposes.  The books which he calls “books universally acknowledged” are in fact used and quoted in time remaining works of Christian writers, during the 250 years between the apostles’ time and that of Eusebius, much more frequently than, and in a different manner from, those the authority of which, he tells us, was disputed.
