45 "Although difficulties and dangers are every day multiplying, the pious and fervent priest must not for that be discouraged-he must not abandon his duties or even draw rein in the accomplishment of the spiritual mission he has received for the welfare and salvation of mankind and for the maintenance of that august religion of which he is herald and minister. For it is especially by difficulties and trials that his virtue becomes strong and stable; it is in the greatest misfortunes, in the midst of political transformations and social upheavals that the salutary and civilizing influence of his ministry shines forth with greatest brilliancy.
