Simon Peter said unto him, Lord, not my feet only, but also my hands and my head.
All Commentaries on John 13:9 Go To John 13
Cyril of Alexandria
AD 444
He who lately exhibited to us so strongly his opposition to what Christ was doing, and who expressly refused to allow the washing of his feet, now offers not them only, but also hands and head as well. For if, says he, my refusal to assent to Thy wish and Thy deliberate purpose, in the matter of washing my feet, is to be followed by my falling away from my fellowship with Thee, and by my being excluded from the blessings for which I hope; then I will offer Thee my other members also, rather than incur so very frightful a loss. Certainly therefore pious devotion was the motive of the former refusal: it was the behaviour of one who feared to submit to the action because there seemed to be something about it which he could not bring himself to tolerate, and not at all the conduct of one who set himself in opposition to his master's injunctions. For bearing in mind, as I said, both the dignity of the Saviour and the utter unworthiness of his own nature, he at first refused; but on learning the jeopardy in which he had thus put himself, immediately he hastens to change his will so as to conform to the good pleasure of his Master.
But look again closely, and accept what was done as a pattern for our profit. For in spite of having said: Thou shalt never wash my feet, he in a moment changes from his purpose thus expressed, not allowing it to be the uppermost thought in his mind that he ought to appear truthful in the eyes of men by adhering to his own words, but rather [influenced by the warning] that he would find a greater and more grievous loss to be the necessary consequence of holding to what he had said. Therefore every one ought to guard against using rash and hasty words, and no one ought in a spirit of violent energy to hastily urge a course of action, which on account of its very recklessness may be afterwards bitterly regretted. But if anything should ever happen to be said by any one in such a way that by persistence in adhering to it something of great value and importance would suffer harm, let the speaker in such a case learn from the words before us that it is very much better for him not to preserve consistency, and not to vainly carry out an intention merely because he has once given expression to it, but rather to use all his efforts to do what will really be profitable to him. For every one, I imagine, will allow that it is safer to incur an indictment for inconsistency in our words, than to suffer a loss of indispensable blessings. And let swearing be altogether absent from our conversation; for words are often spoken on the spur of the moment and without deliberate intention, and our plans are necessarily liable to occasional change and chance. For surely it may be called a worthy and in very truth an enviable possession, to have a discreet tongue, that very rarely lapses into unbefitting language. And since even the Divine Scripture itself has shown to us that the matter is one for violent and tedious struggling----for, as it is written, the tongue can no man tame,----let us keep the utterance of our words free from oaths. For then, if circumstances compel us to refrain from carrying out something we have said, the blame will be less, and our error will be liable to a less severe indictment. And readily will pardon be granted, I think, even by God Himself, for the thoughtless levity of language that is ever besetting us: for who can understand his errors? according to that which is written. Else surely man would utterly perish from the face of the earth, since most easily does language fall away into mistakes of all kinds; for it is a work of the greatest difficulty to keep our tongue under due restraint.
