26. It is of first and primary importance that the supreme Deity be reverenced and His holy laws obeyed in private and in public life; otherwise, there is no human power capable of checking and keeping under due control the unleashed passions of peoples. Religion alone provides the support for what is right and honorable.
27. There is another lesson and admonition given us by the holy Patriarch of which our age stands so much in need – namely, that God is not only to be honored and adored but must be loved as a Father with great charity. Charity has indeed grown cold and lies dormant so that very many seek things of the earth rather than things of heaven; whence conflicting strifes give rise to frequent quarrels and foment distrust and bitter enmities. Since the eternal Deity is the author of our life and from Him we have received numerous gifts it is our strict duty to love Him ardently and to direct and give ourselves and all we have to Him. From this divine love fraternal charity towards our neighbor should arise, which will lead us to consider all as brothers in Christ of whatever stock or nation or culture. Thus from all nations and from all the classes of a country there will arise a single Christian family whose members will not be divided by exaggerated personal interests but will cooperate with each other harmoniously and in friendly wise.
