During the past half century, throughout the Christian world both Catholic and Protestant, great progress has been made in the scientific and critical study of the biblical text, more particularly of the New Testament documents, and, in continuation of this, of the history of Christian origins. The Encyclical Divino afflante Spiritu of the present Pope bears witness to the multiple sources of progress in biblical studies and gives directives concerning it which envisage and prepare for still greater progress to come by Catholic scholars in this field. The appearance two years ago of A Catholic Commentary on Holy Scripture, to cite only the most comprehensive instance amongst much other evidence, is witness also to the fact that in England Catholics are taking a share, fuller than hitherto, in this general movement of Christian scholarship, and that in doing so they are able gratefully to acknowledge and make use of the fruits of much of its labours.
One of the most striking effects of progress in biblical scholarship and the study of Christian origins has been a deeper realization of the fact and extent of doctrinal development down the centuries, and its bearing upon our conception of the nature and function of that Tradition by which such development has been brought about. The view one takes of the nature and function of Tradition in the development of doctrine is inevitably bound up with one’s view of the nature and function of the Church, as the receptacle, so to say, and guardian and interpreter of God’s revelation concerning his means and method of redeeming mankind.
