Clerical Narcissism is a problem that afflicts many priests who think that the Mass is a venue to assert their own personality and preferences. I agree with George Weigel with his observation that this narcissism needs to be corrected.
"One implicit purpose of the new translations, with their deliberate recovery of a sacral vocabulary and their adoption of a more formal literary rhythm, was to discipline the tendency of priests to turn the Mass into an expression of the celebrant’s personality. The difficulties some priests have had with adjusting to the changes suggests that this tendency was, in fact, a real problem in implementing the reforms of the Second Vatican Council. Prominent Catholic psychologist Paul Vitz once wrote of this as a problem of “clerical narcissism,” and while the phrase undoubtedly stings, there’s something to it—something that needs correcting."
