115 But as you well know, Venerable Brethren and beloved sons, the problems that beset men today—and affect Christianity also—are so vast and varied that priests, religious men, and holy virgins seem now unequal to the task of providing the complete remedy.

Many men ignore or avoid them; some, alas, even despise and abhor them.
