92 What torrents of benefits would be showered on the world; what light, order, what peace would accrue to social life; what unique and precious energies would contribute towards the betterment of mankind, if men would everywhere concede to the Church, teacher of justice and love, that liberty of action to which, in virtue of the Divine Mandate, she has a sacred and indisputable right! What calamities could be averted, what happiness and tranquillity assured, if the social and international forces working to establish peace would let themselves be permeated by the deep lessons of the Gospel of Love in their struggle against individual or collective egoism!
