41 There are, of course, some changes which are advantageous and calculated to advance the kindgom of God in men's souls and in society. But, as the Holy Gospel tells us,(32) it is the province of the "Father of the household" and not of the children or servants to examine them, and, if he judges well, to give them currency side by side with the time-honored and venerable usages, which make up the rest of his treasury.
