This article presents a problem of delimiting parts of the Extensive Edition of the Life of St. Sergius of Radonezh, begun by Epiphanius the Wise and completed, as well as in places edited, by Pachomius Logofet. One of the methods of distinguishing the parts is to compare the principles of citing Biblical texts. The identification of allusions, quotations, toposes and biblicalisms makes it possible to oppose Epiphanian and Pachomian “scriptures” more clearly.
This research reveals 7 new quotes in the preface to the Extensive Edition of the Life of St. Sergius of Radonezh in addition to 25 previously commented quotes. The prefa­ce to the Life of St. Sergius of Radonezh, to the life of Stephen of Perm, the author of which is Epiphanius the Wise, the preface to the Lifes of Nikon of Radonezh and Kirill Belozersky, written by Pachomius Logofet, were considered from the position of citation richness.
