Chapter XIX.
Of the clause "Thy kingdom come."
The second petition of the pure heart desires that the kingdom of its Father may come at once; viz., either that whereby Christ reigns day by day in the saints (which comes to pass when the devil's rule is cast out of our hearts by the destruction of foul sins, and God begins to hold sway over us by the sweet odour of virtues, and, fornication being overcome, charity reigns in our hearts together with tranquillity, when rage is conquered; and humility, when pride is trampled under foot) or else that which is promised in due time to all who are perfect, and to all the sons of God, when it will be said to them by Christ: "Come ye blessed of My Father, inherit the kingdom prepared for you from the foundation of the world;" [1611] (as the heart) with fixed and steadfast gaze, so to speak, yearns and longs for it and says to Him "Thy kingdom come." For it knows by the witness of its own conscience that when He shall appear, it will presently share His lot. For no guilty person would dare either to say or to wish for this, for no one would want to face the tribunal of the Judge, who knew that at His coming he would forthwith receive not the prize or reward of his merits but only punishment.
[1611] S. Matt. xxv. 34.
Chapter XX.
Of the clause "Thy will be done."
The third petition is that of sons: "Thy will be done as in heaven so on earth." There can now be no grander prayer than to wish that earthly things may be made equal with things heavenly: for what else is it to say "Thy will be done as in heaven so on earth," than to ask that men may be like angels and that as God's will is ever fulfilled by them in heaven, so also all those who are on earth may do not their own but His will? This too no one could say from the heart but only one who believed that God disposes for our good all things which are seen, whether fortunate or unfortunate, and that He is more careful and provident for our good and salvation than we ourselves are for ourselves. Or at any rate it may be taken in this way: The will of God is the salvation of all men, according to these words of the blessed Paul: "Who willeth all men to be saved and to come to the knowledge of the truth." [1612] Of which will also the prophet Isaiah says in the Person of God the Father: "And all Thy will shall be done." [1613] When we say then "Thy will be done as in heaven so on earth," we pray in other words for this; viz., that as those who are in heaven, so also may all those who dwell on earth be saved, O Father, by the knowledge of Thee.

Chapter XXI.
Of our supersubstantial or daily bread.
Next: "Give us this day our bread which is epiousion," i.e., "supersubstantial," which another Evangelist calls "daily." [1614] The former indicates the quality of its nobility and substance, in virtue of which it is above all substances and the loftiness of its grandeur and holiness exceeds all creatures, while the latter intimates the purpose of its use and value. For where it says "daily" it shows that without it we cannot live a spiritual life for a single day. Where it says "today" it shows that it must be received daily and that yesterday's supply of it is not enough, but at it must be given to us today also in like manner. And our daily need of it suggests to us that we ought at all times to offer up this prayer, because there is no day on which we have no need to strengthen the heart of our inner man, by eating and receiving it, although the expression used, "today" may be taken to apply to his present life, i.e., while we are living in this world supply us with this bread. For we know that it will be given to those who deserve it by Thee hereafter, but we ask that Thou wouldest grant it to us today, because unless it has been vouchsafed to a man to receive it in this life he will never be partaker of it in that.
[1614] Here Cassian is relying entirely on Jerome's revised text of the Latin, which has supersubstantialis in S. Matt. vi. 11, as the rendering of epiousios but translates the same word by quotidianum in the parallel passage in S. Luke xi. 3. It is curious that Cassian should have been thus misled, with his knowledge of Greek, as well as his acquaintance with the old Latin version which has quotidianum in both gospels. Cf. Bishop Lightfoot "On a Fresh Revision of the New Testament," p. 219.
