“Therefore we always teach that the Sacraments and all external things which God ordains and institutes should not be regarded according to the coarse, external mask, as we regard the shell of a nut, but as the Word of God is included therein. For thus we also speak of the parental estate and of civil government. If we propose to regard them in as far as they have noses, eyes, skin, and hair, flesh and bones, they look like Turks and heathen, and some one might start up and say: Why should I esteem them more than others? But because the commandment is added: Honor thy father and thy mother, I behold a different man, adorned and clothed with the majesty and glory of God. The commandment (I say) is the chain of gold about his neck, yea, the crown upon his head, which shows to me how and why one must honor this flesh and blood.”
