"Further, whilst Jesus was kind to sinners and to those who went
astray, He did not respect their false ideas, however sincere they might have appeared. He loved them all, but He instructed them in order to convert them and save them. Whilst He called to Himself in order to comfort them, those who toiled and suffered, it was not to preach to them the jealousy of a chimerical equality. Whilst He lifted up the lowly, it was not to instill in them the sentiment of a dignity independent from, and rebellious against, the duty of obedience. Whilst His heart overflowed with gentleness for the souls of good-will, He could also arm Himself with holy indignation against the profaners of the House of God, against the wretched men who scandalized the little ones, against the authorities who crush the people with the weight of heavy burdens without putting out a hand to lift them.
He was as strong as he was gentle. He reproved, threatened, chastised, knowing, and teaching us that fear is the beginning of wisdom, and that it is sometimes proper for a man to cut off an offending limb to save his body. Finally, He did not announce for future society the reign of an ideal happiness from which suffering would be banished; but, by His lessons and by His example, He traced the path of the happiness which is possible on earth and of the perfect happiness in heaven: the royal way of the Cross. These are teachings that it would be wrong to apply only to one's personal life in order to win eternal salvation; these are eminently social teachings, and they show in Our Lord Jesus Christ something quite different from an inconsistent and impotent humanitarianism."
Pope St. Pius X.
