I pray that I may have God as my guide and the power of the Lord as my aid, since I am unable to find even the bare footsteps of those who have traveled the way before me, except in brief fragments, in which some in one way, others in another, have transmitted to us particular accounts of the times in which they lived” (Eusebius, The Church History, Translated by Arthur McGiffert, I.I.4.).
“This work seems to me of especial importance because I know of no ecclesiastical writer who has devoted himself to this subject; and I hope that it will appear most useful to those who are fond of historical research” (I.I.6.)
