"The Church having received this preaching and this faith, as we have said before, although it be scattered abroad through the whole world, carefully preserves it, dwelling as in one habitation, and believes alike in these (doctrines) as though she had one soul and the same heart: and in strict accord, as though she had one mouth, proclaims, and teaches, and delivers onward these things. And although there may be many diverse languages in the world, yet the power of the tradition is one and the same. And neither do the Churches planted in Germany believe otherwise, or otherwise deliver (the faith), nor those in Iberia, nor among the Celtae, nor in the East, nor in Egypt, nor in Libya, nor they that are planted in the mainland. But as the sun, which is God's creature, in all the world is one and the same, so also the preaching of the truth shineth everywhere, and lightened all men that are willing to come to the knowledge of the truth. And neither will any ruler of the Church, though he be mighty in the utterance of truth, teach otherwise than thus (for no man is above the master), nor will he that is weak in the same diminish from the tradition; for the faith being one and the same, he that is able to say most of it hath nothing over, and he that is able to say least hath no lack."* * St. Irenaeus, lib. i. c. x. To St. Irenaeus, then, the Church was "the irrefragable witness of its own legation." When did it cease so to be? It would be easy to multiply quotations from Tertullian in A. D. 200, from St. Cyprian a. d. 250, from St. Augustine and St. Optatus in A. d. 350, from St. Leo in a. d. 450, all of which are on the same traditional lines of faith in a divine mission to the world and of a divine assistance in its discharge. But I refrain from doing so because I should have to write not an article but a folio. Any Catholic theology will give the passages which are now before me; or one such book as the Loci Theologici of Melchior Canus will suffice to show the continuity and identity of the tradition of St. Irenaeus and the tradition of the Vatican Council, in which the universal church last declared the immutable faith and its own legation to mankind.
