I was reminded of this quote from Hugh of St. Victor (1096-1141) reading Ephraim Radner recently:
. . .for all divine Scripture is one book, and this one book is Christ, for all divine Scripture speaks of Christ and all divine Scripture is fulfilled in Christ. . .
. . .quia omnis Scriptura divina unus liber est, et ille unus liber Christus est, quia omnis Scriptura divina de Christo loquitur, et omnis Scriptura divina in Christo impletur. . . (De arca Noe morali 2.8, PL176: 642)
