Summi Pontificatus §64

⁶⁴ True courage and a heroism worthy in its degree of admiration and respect, are often necessary to support the hardships of life, the daily weight of misery, growing want and restrictions on a scale never before experienced, whose reason and necessity are not always apparent. Whoever has the care of souls and can search hearts, knows the hidden tears of mothers, the resigned sorrow of so many fathers, the countless bitterness of which no statistics tell nor can tell He sees with sad eyes the mass of sufferings ever on the increase; he knows how the powers of disorder and destruction stand on the alert ready to make use of all these things for their dark designs.
