And something of the same degree of uncertainty must in like manner hang about the transmission of doctrines or opinions by such a channel. And it is to be remembered that Irenæus, when he testifies of these, is not in the same position as when he speaks of public doctrine, discipline, or customs. There he is the witness of the combined teaching of many lines of apostolical succession; here, for all that appears, of only one: and that one requires to be checked or confirmed by other evidence before it can gain our full assent. If what is gained in this way fall in with Scripture, or explains or carries out more fully the meaning of Scripture in a manner not inconsistent with other Scripture, then we may feel that it is to be treasured up, as being in all probability a fragment of apostolical tradition. If, again, it is confirmed by other sufficient testimony, it may be looked upon in the same light, in proportion to the degree of evidence: for although Irenæus unquestionably quoted these latter traditions as undoubted truths, it is impossible that they should, upon his single testimony, appear so to our minds. There is, however, one general remark which applies to all the various instances in which he appeals to tradition, and that is, that he does not appear to have known any thing of a transmitted comment on the text of Scripture. The only way in which he applies tradition to the interpretation of Scripture is, by laying down certain facts of our Lord’s history, which were universally acknowledged or handed down by sufficient testimony, or certain doctrines of religion or general principles which were universally received as of apostolical authority, and bringing them forward in confirmation of the views which he himself deduced from a comparison and accumulation of texts. CHAPTER X. ON THE CREED. The Baptismal Creed having been mentioned in the two previous chapters, in the one as a guide in the interpretation of Scripture, in the other as embodying (to a certain extent) Primitive Tradition, it appears natural to bring forward in the next place such notices of it as Irenæus furnishes. We find, then, that it was customary at baptism to rehearse to every person the rule of faith held throughout the Catholic Church; in other words, the Creed(364). This, indeed, was not uniform in language, but the same points appear to have been adhered to, and to have been stated in much the same order. Irenæus, indeed, does not distinctly copy any creed: but he rehearses all the chief points of it in two different passages, which I will give at length; these being the first clear traces we have of the primitive creed. The first is as follows(365):—
