Tolerance on balance is a good thing.
Tolerance of a person, hardly tolerance of wrong.
Cardinal Ratzinger: I would say that a man of conscience is one who never acquires tolerance, well-being, success, public standing, and approval on the part of prevailing opinion at the expense of truth.” (The Priest, Autumn, 1993).
As Archbishop Fulton J Sheen has written: we “are suffering from tolerance: tolerance of right and wrong, truth and error, virtue and evil, Christ and chaos.
“A person who can make up his or her mind in an orderly way, as a person might make up a bed, is called a bigot; but a person who cannot make up his or her mind, any more than one can make up for lost time, is called tolerant and broadminded.”
Address of Papal Theologian on Natural Moral Law
The Moral Natural Law: Problems and Prospects
“In fact, in the Western world, at least in the public sphere, there is bleeding atrophy of understanding what is natural and what is not, leading to changes in ethical mores that are amounting to a profound revolution of the foundations of civilization. These changes are not taking place in the name of some forceful ideology, capable of mustering the support of crowds – as was the case with nationalism and communism, both of which had an altruist element within them – but in the name of pure hedonism and anti-rationalist skepticism, hidden under the mask of tolerance.
“What is perplexing, however, is that these new concepts of new virtues are nebulous or ambivalent, and deprived of any rooting in coherent and certain knowledge about the human person, about human nature and its finality. If in the name of tolerance, no certain knowledge may be had about anything, if no one is entitled to declare that he holds any truths as true and therefore universally binding, there is no place for any virtue at all, and all supposedly value-charged statements are in fact empty.”
To quote Dr Jeff Mirus:
“…universal tolerance means the acceptance (and therefore tacit approval) of all behaviors, irrespective of their impact on the common good and on human flourishing. To put the matter simply, tolerance perceived as a virtue always rewards vice….The invocation of tolerance as a virtue will always undermine prudence, the real and necessary virtue that enables us to match proper solutions to particular problems.”
