Tertullian

“ But you will think that God must be found fault with, and that for being jealous, if He has chosen to contend with a disease and to do good by imitating the malady, to destroy death by death, to dissipate killing by killing, to dispel tortures by tortures, to disperse [1] punishments by punishments, to bestow life by withdrawing it, to aid the flesh by injuring it, to preserve the soul by snatching it away. The wrongheadedness, as you deem it to be, is reasonableness; what you count cruelty is kindness. ”

“ Man always first provides employment for the physician; in short, he has brought upon himself the danger of death. He had received from his own Lord, as from a physician, the salutary enough rule to live according to the law, that he should eat of all indeed (that the garden produced) and should refrain from only one little tree which in the meantime the Physician Himself knew as a perilous one. ”

“ The good accruing is the apology for the frightfulness of the work. In short, that man who is howling and groaning and bellowing in the hands of a physician will presently load the same hands with a fee, and proclaim that they are the best operators, and no longer affirm that they are cruel. ”

“ God also will be at liberty to heal for everlasting life by means of fires and swords, and all that is painful. But you will admire the physician at least even in that respect, that for the most part he employs like properties in the cures to counteract the properties of the diseases, when he aids, as it were, the wrong way, succouring by means of those things to which the affliction is owing. ”

“ This frowardness also appertains to men,—to discard what is wholesome, to accept what is baleful, to avoid all dangerous cures, or, in short, to be eager to die rather than to be healed. For they are many who flee from the aid of physic also, many in folly, many from fear and false modesty. ”

“ For if any one make the supposition that God is evil, he will not be able to take his stand on both the constituents thereof: he will be bound either to affirm that he whom he has thought to be evil is not God, or that he whom he has proclaimed to be God is good. ”

“ It would be tedious to show that my God is good,—a truth with which the Marcionites have now been made acquainted by us. Meanwhile it is enough that He is called God for its being necessary that He should be believed to be good. ”

“ And the healing art has manifestly an apparent cruelty, by reason of the lancet, and of the burning iron, and of the great heat of the mustard; yet to be cut and burned, and pulled and bitten, is not on that account an evil, for it occasions helpful pains ”
