The Doubtful Letters
Holy in Body and Spirit
Next comes the phrase “how she may please God”—God, I say, not people—“so that she may be holy both in body and in spirit.” He does not say that she may be holy only in one member, or only in the body, but that she may be holy in body and in spirit. For a member is only one part of the body, but the body is the union of all the members. So when he says that she should be holy in the body, he is testifying that she ought to be made holy in all her members, because the holiness of the other members will be of no use if corruption is found remaining in one. Nor will she be holy in body, which is made up of all the members, if she is defiled by the pollution of even one of them.
To make what I am saying plainer and clearer, imagine a woman whose other members are all purified and made holy, who sins only with her tongue, because she either speaks evil of people or bears false witness. Will all her other members win the acquittal of the one, or will all the rest be judged on account of the one? If, then, the holiness of the other members is of no use even when only one is at fault, how much less will the perfection of one be of any use if all are corrupted by the guilt of various sins?
