John Chrysostom (attributed)

These words, As in heaven so in earth, must be taken as common to all three preceding petitions. Observe also how carefully it is worded; He said not, Father, hallow Thy name in us, Let Thy kingdom come on us, Do Thy will in us. Nor again; Let us hallow Thy name, Let us enter into Thy kingdom, Let us do Thy will; that it should not seem to be either God’s doing only, or man’s doing only. But He used a middle form of speech, and the impersonal verb; for as man can do nothing good without God’s aid, so neither does God work good in man unless man wills it.
