Since the Holy See is involved in liturgical reform, we naturally ought to assume that at least in the minds of the scholars and pastors who are engaged in it, the work is relevant. The details of this reform are obviously chosen for pastoral reasons. In other words the concern was definitely and decidedly one of the spiritual welfare of ordinary Catholics, not only of an elite of archaeologists, historians and those who use their missals with understanding and devotion. This pastoral concern is the one thing all liturgical reforms have in common. Damasus I was probably the pope who established the vernacular Latin, Gregory I remade the calendar and the music, Gregory VII stabilized the Franco-Roman form and Trent froze the best available text in its present form. Thus we must assume that the recent changes were supposed to be relevant to the spiritual growth of the average more or less instructed faithful.
