Thus Grace is for ever associated with Truth as the means whereby alone on earth Truth shall prevail and be received, and that only as the teaching of that Body whose Head is full of Grace and Truth. Fifthly, there is marked the manner of the teaching, the nature of the magisterial office created as that of a living body of men: “teaching them to observe all things whatsoever I have commanded you.” The fund from which this teaching is drawn is that whole communication of truth from the Incarnate Word Himself, given to them by word of mouth, of which we have spoken above as the great Tradition or Delivery; and out of which a part is incorporated in the written word, while the whole dwells ever in the Body created to receive it, from which it is to be imparted by perpetual oral teaching. The teaching, therefore, rests upon the perpetual presence of the Body representing Christ, and as in the days of His flesh He teaches through it, and has fixed part of His tradition in it by writing, not to the exclusion of the rest, but as the charter of a sovereign, the title-deeds of an empire, to be perpetually applied, interpreted, and developed in that whole system of institutions, by that whole race of teachers, in the life of that one Body, which He was creating. And lastly, to this perpetual living line of teachers, to this perpetual living doctrine, to this perpetual living framework of grace, He has promised His own presence without fail to the end. In this triple succession He is seen, lives, and rules, and this is His Kingdom, His Temple, His Body, His Bride, His Family, to whom He says, Behold, I am with you all days, even to the end of the world.
