“If we would hold the true course in love, our first step must be to turn our eyes not to man, the sight of whom might oftener produce hatred than love, but to God, who requires that the love which we bear to him be diffused among all mankind, so that our fundamental principle must ever be, Let a man be what he may, he is still to be loved because God is loved.”
–Calvin, Institutes
