For it is not possible for any man to write well about it, or to understand well what is rightly written, who has not at some time tasted of its spirit, under the pressure of tribulation; while he who has tasted of it, even to a very small extent, can never write, speak, think, or hear about it sufficiently. For it is a living fountain, springing up into eternal life, as Christ calls it in John iv.
A Christian man is the most free lord of all, and subject to none; a Christian man is the most dutiful servant of all, and subject to every one.
What can it profit the soul that the body should be in good condition, free, and full of life; that it should eat, drink, and act according to its pleasure; when even the most impious slaves of every kind of vice are prosperous in these matters? Again, what harm can ill-health, bondage, hunger, thirst, or any other outward evil, do to the soul, when even the most pious of men and the freest in the purity of their conscience, are harassed by these things? Neither of these states of things has to do with the liberty or the slavery of the soul.
And so it will profit nothing that the body should be adorned with sacred vestments, or dwell in holy places, or be occupied in sacred offices, or pray, fast, and abstain from certain meats, or do whatever works can be done through the body and in the body. Something widely different will be necessary for the justification and liberty of the soul, since the things I have spoken of can be done by any impious person, and only hypocrites are produced by devotion to these things.
