Equality is to be found only in the spiritual dignity of man, and that will only be understood among us. If we were brothers, there would be fraternity, but before that, they will never agree about the division of wealth.

Context

“It will come to pass, that even the most corrupt of our rich will end by being ashamed of his riches before the poor, and the poor, seeing his humility, will understand and give way before him, will respond joyfully and kindly to his honorable shame. Believe me that it will end in that; things are moving to that. Equality is to be found only in the spiritual dignity of man, and that will only be understood among us. If we were brothers, there would be fraternity, but before that, they will never agree about the division of wealth. We preserve the image of Christ, and it will shine forth like a precious diamond to the whole world. So may it be, so may it be!
