11 C. I simply said that we find the help of God not in our several actions, but in the grace of creation and of the law, that free will might not be destroyed. But there are many of us who maintain that all we do is done with the help of God.
A. Whoever says that must leave your party. Either, then, say the same yourself and join our side, or, if you refuse, you will be just as much our enemy as those who do not hold our views.
C. I shall be on your side if you speak my sentiments, or rather you will be on mine if you do not contradict them. You admit health of body, and deny health of the soul, which is stronger than the body. For sin is to the soul what disease or a wound is to the body. If then you admit that a man may be healthy so far as he is flesh, why do you not say he may be healthy so far as he is spirit?
A. I will follow in the line you point out,
and you today
Shall ne'er escape; where'r you call, I come.
C. I am ready to listen.
A. And I to speak to deaf ears. I will therefore reply to your argument. Made up of soul and body, we have the nature of both substances. As the body is said to be healthy if it is troubled with no weakness, so the soul is free from fault if it is unshaken and undisturbed. And yet, although the body may be healthy, sound, and active, with all the faculties in their full vigour, yet it suffers much from infirmities at more or less frequent intervals, and, however strong it may be, is sometimes distressed by various humours; so the soul, bearing the onset of thoughts and agitations, even though it escape shipwreck, does not sail without danger, and remembering its weakness, is always anxious about death, according as it is written, “What man is he that shall live and not see death?”— death, which threatens all mortal men, not through the decay of nature, but through the death of sin, according to the prophet's words, “The soul that sins, it shall die.” Besides, we know that Enoch and Elias have not yet seen this death which is common to man and the brutes. Show me a body which is never sick, or which after sickness is ever safe and sound, and I will show you a soul which never sinned, and after acquiring virtues will never again sin. The thing is impossible, and all the more when we remember that vice borders on virtue, and that, if you deviate ever so little, you will either go astray or fall over a precipice. How small is the interval between obstinacy and perseverance, miserliness and frugality, liberality and extravagance, wisdom and craft, intrepidity and rashness, caution and timidity! some of which are classed as good, others as bad. And the same applies to bodies. If you take precautions against biliousness, the phlegm increases. If you dry up the humours too quickly, the blood becomes heated and vitiated with bile, and a sallow hue spreads over the countenance. Without question, however much we may exercise all the care of the physician, and regulate our diet, and be free from indigestion and whatever fosters disease, the causes of which are in some cases hidden from us and known to God alone, we shiver with cold, or burn with fever, or howl with colic, and implore the help of the true physician, our Saviour, and say with the Apostles, “Master, save us, we perish.”
