The aim of this article is twofold. Both Origen and Gregory of Nyssa treat of the Lord’s Prayer, the former in his own treatise On Prayer, the latter in the course of five sermons on the same prayer. By means of an analysis of the methods of both writers and of the results at which they arrive I hope to illustrate their respective treatments of the same text and so to show how what began life as an eschatological prayer became (...) in the course of three or four centuries something rather different. A major difficulty faced by both writers is how to understand the coming of the kingdom, if it is already there.My second intention, beyond that of comparison is to assess what influence, if any, was exercised by Origen on Gregory. The answer arrived at is rather disappointing, above all for those who believe in a strong influence on Gregory of his predecessor, by way of his grandmother, Macrina. Not only are the styles of the two men quite different, but also, apart from a sort of common Platonism, their answers are often quite distinct. (shrink)
