collection of ancient holy addresses, first seems to have received the name of James in tradition. (8) The first Epistle of Peter, which originally appears to have been written by an unknown follower of Paul, first received its present name from tradition. The same thing perhaps holds good of the Epistle of Jude. Tradition was similarly at work, even at a later period, as may for example be recognised by the transformation of the epistle "de virginitate" into two writings by Clement. The critics of early Christian literature have created for themselves insoluble problems by misunderstanding the work of tradition. Instead of asking whether the tradition is reliable, they always wrestle with the dilemma "genuine or spurious", and can prove neither.] [Footnote 93: As regards its aim and contents, this book is furthest removed from the claim to be a portion of a collection of Holy Scriptures. Accordingly, so far as we know, its reception into the canon has no preliminary history.] [Footnote 94: People were compelled by internal and external evidence (recognition of their apostolicity; example of the Gnostics) to accept the epistles of Paul. But, from the Catholic point of view, a canon which comprised only the four Gospels and the Pauline Epistles, would have been at best an edifice of two wings without the central structure, and therefore incomplete and uninhabitable. The actual novelty was the bold insertion into its midst of a book, which, if everything is not deceptive, had formerly been only in private use, namely, the Acts of the Apostles, which some associated with an Epistle of Peter and an Epistle of John, others with an Epistle of Jude, two Epistles of John, and the like. There were now (1) writings of the Lord which were at the same time regarded as [Greek: apomnemoneumata] of definite Apostles; (2) a book which contained the acts and preaching of all the Apostles, which historically legitimised Paul, and at the same time gave hints for the explanation of "difficult" passages in his Epistle; (3) the Pauline Epistles increased by the compilation of the Pastoral ones, documents which "in ordinatione ecclesiasticae disciplinae sanctificatae erant." The Acts of the Apostles is thus the key to the understanding of the Catholic canon and at the same time shows its novelty. In this book the new collection had its bond of cohesion, its Catholic element (apostolic tradition), and the guide for its exposition. That the Acts of the Apostles found its place in the canon _faute de mieux_ is clear from the extravagant terms, not at all suited to the book, in which its appearance there is immediately hailed. It is inserted in place of a book which should have contained the teaching and missionary acts of all the 12 Apostles; but, as it happened, such a record was not in existence. The first evidence regarding it is found in the Muratorian fragment and in Irenaeus and Tertullian. There it is called "acta omnium
