It is Christianity, above all others, which teaches the full truth, real justice, and that divine charity which drives away hatred, ill will, and enmity. Christianity has been given charge of these virtues by the Divine Redeemer, who is the way, the truth, and the life, and she must do all in her power to put them to use. Anyone, therefore, who knowingly ignores Christianity -- the Catholic Church -- or tries to hinder, demean, or undo her, either weakens thereby the very bases of society, or tries to replace them with props not strong enough to support the edifice of human worth, freedom, and well-being.
--Pope Pius XII, Memnisse Iuvat, 1958
