Pope Gregory XVII (1906-1989 A.D.)
"Peace is tranquility in order,
an order reposing in God as the Author of all things.
Man cannot arbitrarily create that order, which by its very nature transcends all
men and all times. The same dilemma is always found at the base of all problems
of mankind: respect or scorn for the laws fixed by the divine order. ... Peace
society and between different nations demands a clear recognition and observance
of certain principles.
To question these principles is already to make war."
