11 Hence the Church's heroic and impatient struggle for renewal: the struggle to correct those flaws introduced by its members which its own self-examination, mirroring its exemplar, Christ, points out to it and condemns. And this brings us, Venerable Brethren, to the second policy We have in mind at this time: to bring the members of the Church to a clearer realization of their duty to correct their faults, strive for perfection, and make a wise choice of the means necessary for achieving the renewal We spoke of. We tell you this not only that We may Ourself find greater courage to introduce the appropriate reforms, but also in order to secure your sympathy, advice, and support in a matter of such urgency and difficulty.
