“The next champion for the propagation of Apostolic Succession, is Eusebius himself. Is the word of this Armenian Father any better than that of Irenaeus? Let us see what the most competent critics say of him. And before we turn to modern critics at all, we might remind the reader of the scurrilous terms in which Eusebius is attacked by George Syncellus, the Vice Patriarch of Constantinople (eighth century), for his audacious falsification of the Egyptian Chronology. The opinion of Socrates, a historian of the fifth century, is no more flattering. He fearlessly charges Eusebius with perverting historical dates, in order to please the Emperor Constantine.
In his chronographic work, before proceeding to falsify the synchronistic tables himself, in order to impart to Scriptural chronology a more trustworthy appearance, Syncellus covers Eusebius with the choicest of monkish Billingsgate. Baron Bunsen has verified the justness if not justified the politeness of this abusive reprehension. His elaborate researches in the rectification of the Egyptian List of Chronology, by Manetho, led him to confess that throughout his work, the Bishop of Caesarea “had undertaken, in a very unscrupulous and arbitrary spirit, to mutilate history.” “Eusebius”, he says, “is the originator of that systematic theory of synchronisms which has so often subsequently maimed and mutilated history in its procrustean bed.” To this the author of the Intellectual Development of Europe adds: “Among those who have been the most guilty of this offense, the name of the celebrated Eusebius, the Bishop of Caesarea…should be designated!”
It will not be amiss to remind the reader that it is the same Eusebius who is charged with the interpolation of the famous paragraph concerning Jesus, which was so miraculously found, in his time, in the writings of Josephus, the sentence in question having till that time remained perfectly unknown. Renan, in his Life of Jesus, expresses a contrary opinion. “I believe”, says he, “the passage respecting Jesus to be authentic. It is perfectly in the style of Josephus; and, if this historian had made mention of Jesus, it is thus that he must have spoken of him.”
