Gregory the Great — on Ezek 3:3 (Homilies on Ezekiel, Book 1, Homily 10)

“Let us consider, my dearest brothers, how gracious is that promise by which it is said: "Your belly shall eat, and your bowels shall be filled with this scroll which I give you." For many read, and from that very reading they remain hungry. Many hear the voice of preaching, but after the voice they depart empty. Though their belly eats, their bowels are not filled, because even if they perceive in their mind the understanding of the sacred word, by forgetting and not keeping what they have heard, they do not store these things in the bowels of their heart. Hence it is that through another prophet the Lord rebukes certain people, saying: "Set your hearts upon your ways. You have sown much, and brought in little; you have eaten, and have not been satisfied; you have drunk, and have not been inebriated." He sows much in his heart but brings in little who learns many things about the heavenly commandments either by reading or even by hearing, but by working negligently produces little fruit. He eats and is not satisfied who, hearing the words of God, desires the profits or glory of the world. And rightly is he said not to be satisfied, because he chews one thing and hungers for another. He drinks and is not inebriated who inclines his ear to the voice of preaching but does not change his mind. For through the inebriation of those who drink, the senses are usually changed. Therefore, he who is devoted to knowing the word of God but desires to obtain the things of this world drinks and is not inebriated. For if he had been inebriated, he would without doubt have changed his mind, so that he would no longer seek earthly things, and would no longer love the vain and transitory things he had loved. For of the elect it is said through the Psalmist: "They shall be inebriated from the abundance of your house." Because they are so filled with the love of almighty God that with changed minds they seem to be strangers to themselves, fulfilling what is written: "He who wishes to come after me, let him deny himself." He denies himself who is changed for the better and begins to be what he was not, and ceases to be what he was. Often, however, we see certain people at the voice of preaching, as if compelled by conversion, change their habit but not their mind, so that they take up religious garb but do not trample down their former vices: they are savagely driven by the goads of anger, they burn with the pain of malice to injure their neighbor, they grow proud before human eyes over certain goods they have displayed, they greedily seek the profits of the present world, and they place their confidence of holiness solely in the outward habit they have assumed. What else should be said to them except what the excellent teacher says to certain people who observe the externals of the law, saying: "For in Christ Jesus neither circumcision avails anything, nor uncircumcision, but a new creation"? For it is not a matter of great merit if something is done outwardly to us in the body, but what is done in the mind must be carefully weighed. For to despise the present world, not to love transitory things, to lay the mind deeply in humility before God and neighbor, to preserve patience against insults inflicted, and, while guarding patience, to repel the pain of malice from the heart, to give one's own goods to the needy, in no way to covet what belongs to others, to love a friend in God, to love even enemies for God's sake, to grieve over a neighbor's affliction, not to exult over the death of one who is an enemy—this is the new creature, which the same teacher of the Gentiles seeks among other disciples with a watchful eye, saying: "If therefore there is any new creature in Christ, the old things have passed away; behold, all things are made new." To seek the present world belongs indeed to the old man, to love transitory things from concupiscence, to raise the mind in pride, to have no patience, to think from the pain of malice about harming one's neighbor, not to give one's own goods to the needy, and to seek others' goods in order to multiply one's own, to love no one purely for God's sake, to return enmities for enmities, to rejoice at the affliction of one's neighbor. All these things belong to the old man, which indeed we draw from the root of corruption. But concerning the one who now overcomes these things and turns the mind to kindness according to the Lord's precepts, it is rightly said: Because the old things have passed away, behold all things are made new. Then therefore new things come about in our minds when the vices of the old man pass away from us; and the vices of the old man pass away when the belly eats the precept of the sacred word and the inmost parts are filled to the marrow. For we have often seen certain people devote themselves with their whole mind to the study of holy reading, and, recognizing amid the Lord's words how greatly they had sinned, slaughter themselves in tears, be afflicted with continual grief, take delight in none of this world's prosperities, so that the present life became a burden to them and the very light became wearisome; scarcely admit common conversation, and relax their mind from the rigor of discipline with difficulty, for love of their Creator rejoicing only in mourning and silence. Their belly ate the sacred volume, and their inmost parts were filled, because the precepts of life which the understanding was able to grasp the memory did not lose, but the mind, gathered in God, preserved these by always mourning and recalling them.”
