"The supernatural dignity of one who has been baptized rests, we know, on the natural dignity of man, though it surpasses it in an infinite degree.[…] Thus the unity of the Mystical Body of Christ, a supernatural unity, supposes a previous natural unity, the unity of the human race.[…] Was it not shown […] in Genesis where it was taught that God made man in his own image? For the divine image does not differ from one individual to another: in all it is the same image.[…] Whence comes the notion, so beloved of Augustinianism, of one spiritual family intended to form the one city of God."
