Resumen:
The Lutheran principle of sola Scriptura as a source of Revelation generated among the Catholics the tendency to reject Tradition as a means of knowing the Revelation. However, a brief review of the way Luther understands the Sacred Scripture and how the Catholic Church confronted the Reformation in the Councils of Trent and Vatican II can show the positive aspects of the challenge posed by the Reformation. Dei Verbum's formula, according to which the Sacred Scripture, "una cum Sacra Traditione", constitutes the rule of faith and the Church's power and vigor, gives due recognition both to the Catholic point of view and to one of the Reformation's main tenets.
