“The Church has consistently taught that justice and charity are the foundations of peace. It may be right to think of “charity as the soul and justice as the substance of international peace.””

Light (1919), Ch. XX The Cult
Context: There must be justice, not charity. Kindness is solitary. Compassion becomes one with him whom we pity; it allows us to fathom him, to understand him alone amongst the rest; but it blurs and befogs the laws of the whole. I must set off with a clear idea, like the beam of a lighthouse through the deformities and temptations of night.

1900s, Inaugural Address (1905)
Context: While ever careful to refrain from wrongdoing others, we must be no less insistent that we are not wronged ourselves. We wish peace, but we wish the peace of justice, the peace of righteousness. We wish it because we think it is right and not because we are afraid. No weak nation that acts manfully and justly should ever have cause to fear us, and no strong power should ever be able to single us out as a subject for insolent aggression.
