7 When therefore He has reminded us of this nobility, and of the gift from above, and of our equality with our brethren, and of charity; and when He has removed us from earth, and fixed us in Heaven; let us see what He commands us to ask after this. Not but, in the first place, even that saying alone is sufficient to implant instruction in all virtue. For he who has called God Father, and a common Father, would be justly bound to show forth such a conversation, as not to appear unworthy of this nobility, and to exhibit a diligence proportionate to the gift. Yet is He not satisfied with this, but adds, also another clause, thus saying,
“Hallowed be Your name.”
Worthy of him who calls God Father, is the prayer to ask nothing before the glory of His Father, but to account all things secondary to the work of praising Him. For “hallowed” is glorified. For His own glory He has complete, and ever continuing the same, but He commands him who prays to seek that He may be glorified also by our life. Which very thing He had said before likewise, “Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven.” Yea, and the seraphim too, giving glory, said on this wise, “Holy, holy, holy.” So that “hallowed” means this, viz. “glorified.” That is, “vouchsafe,” says he, “that we may live so purely, that through us all may glorify You.” Which thing again appertains unto perfect self-control, to present to all a life so irreprehensible, that every one of the beholders may offer to the Lord the praise due to Him for this.
“Your kingdom come.”
And this again is the language of a right-minded child, not to be rivetted to things that are seen, neither to account things present some great matter; but to hasten unto our Father, and to long for the things to come. And this springs out of a good conscience, and a soul set free from things that are on earth. This, for instance, Paul himself was longing after every day: wherefore he also said, that “even we ourselves, who have the first-fruits of the Spirit, groan, waiting for an adoption, the redemption of our body.” For he who has this fondness, can neither be puffed up by the good things of this life, nor abashed by its sorrows; but as though dwelling in the very heavens, is freed from each sort of irregularity.
“Your will be done in earth, as it is in Heaven.”
Behold a most excellent train of thought! In that He bade us indeed long for the things to come, and hasten towards that sojourn; and, till that may be, even while we abide here, so long to be earnest in showing forth the same conversation as those above. For you must long, says He, for heaven, and the things in heaven; however, even before heaven, He has bidden us make the earth a heaven and do and say all things, even while we are continuing in it, as having our conversation there; insomuch that these too should be objects of our prayer to the Lord. For there is nothing to hinder our reaching the perfection of the powers above, because we inhabit the earth; but it is possible even while abiding here, to do all, as though already placed on high. What He says therefore is this: “As there all things are done without hindrance, and the angels are not partly obedient and partly disobedient, but in all things yield and obey (for He says, 'Mighty in strength, performing His word'); so vouchsafe that we men may not do Your will by halves, but perform all things as You will.”
Do you see how He has taught us also to be modest, by making it clear that virtue is not of our endeavors only, but also of the grace from above? And again, He has enjoined each one of us, who pray, to take upon himself the care of the whole world. For He did not at all say, “Your will be done” in me, or in us, but everywhere on the earth; so that error may be destroyed, and truth implanted, and all wickedness cast out, and virtue return, and no difference in this respect be henceforth between heaven and earth. “For if this come to pass,” says He, “there will be no difference between things below and above, separated as they are in nature; the earth exhibiting to us another set of angels.”
