The vegetarian movement ought to fill with gladness the souls of those who have at heart the realization of God's kingdom upon earth, not because vegetarianism itself is such an important step towards the realization of this kingdom (all real steps are equally important or unimportant), but because it serves as a criterion by which we know that the pursuit of moral perfection on the part of man is genuine and sincere.
