It will be perceived, that these views are not entirely accordant with the sentiments, which have sometimes been entertained by individuals, and even by large bodies of Christians. Many pious persons, at different periods in the history of the church, have maintained, that the various propensities and affections should not merely be crucified in the true scripture sense, viz. by being reduced from an irregular to a subordinate and holy action, but should be exterminated. In accordance with this opinion, obviously erroneous as it is, many persons of both sexes, some of them distinguished for their learning and their rank in life, have avoided, by a permanent principle of action, every thing, that could please the appetites or gratify the demands of our social nature. Influenced by mistaken notions of what Christianity really requires, they have literally made their abode in the dens and caves of the earth; and may be said, with too much foundation in fact, to have rejected the society of man for the companionship of wild beasts. Ecclesiastical history is interspersed with instances of this kind, from the days of the anchorets who macerated their bodies and uttered their solitary prayers in the deserts of Egypt, down to the present time. It is related, for instance, of Catherine of Cardonne, a pious Spanish lady of the 16th century, moving in the first ranks of society, and well accomplished in the endowments of intellect and education, that she retired to a solitary cavern in a remote mountainous region, and spent many years in the strictest seclusion, with no adequate clothing, and with no food but what the uncultivated earth afforded. No one can read the story of the extreme privations, to which she subjected herself, for the purpose of a more intimate communion with God, without a mixed emotion of regret for the errors of her judgment, and of profound respect for the self-sacrificing piety of her heart. There have been many instances of this kind.
There is some reason to think, that many of the class of persons, to whom we have reference in these remarks, placed more reliance on works than on faith. This was a great error, though a candid consideration of their lives will probably justify us in regarding it as an unintentional one. The mighty efficacy of faith, in its relation to the renovation of the human mind, seems not to have been well understood by them. And being left destitute, in a considerable degree, of the aids and consolations which so abundantly flow from that source, they pressed the principle of consecration, which, independently of faith, becomes the imperfect and unsatisfactory principle of mere works, to its extreme limits. They deprived themselves of the necessary sleep; wore garments, that inflicted constant suffering; mingled ashes with their bread; and submitted to other acts and observances of a penitential nature, either to render themselves, in their present characters, more acceptable to God, or to propitiate the divine mercy for the commission of past sins.
With feelings of entire sympathy with the sincerity, which has characterized the conduct of many humble and suffering recluses, we still feel bound to say, that we do not understand the Scriptures as requiring the crucifixion of the appetites and propensities to be carried to this extent. The Scriptures require us to become Christians; but they do not require us to cease to be men. They require us, to put off the "old man," which is fictitious, a perversion of good, and a "liar from the beginning;" but they do not, and could not require us to put off the "new man," which is the same, if not physically and intellectually, yet in all the attributes of the heart, with the primitive or holy man, the man as he existed in Adam before his fall, and as he became re-existent in the stainless Savior. But Christ, who is set before us as our example, ate and drank without sin; he recognized and discharged the duty of social intercourse without sin; and he performed the various other duties, which are appropriate to human nature, in equal freedom from anything that is wrong and unholy.
