It will be noticed that while this canon has often been used for controversial purposes it really has little or no value in this connexion, for the absence of the Revelation of St. John from the New Testament to all orthodox Christians is, to say the least, as fatal to its reception as an ecumenical definition of the canon of Holy Scripture, as the absence of the book of Wisdom, etc., from the Old Testament is to its reception by those who accept the books of what we may call for convenience the Greek canon, as distinguished from the Hebrew, as canonical.
