I translate here the reading of the Parisian Codex called by the Benedictine Editors Regius Secundus, τὸ εὐμετάβολον κατωρθωκότας.  The harder reading, τὸ εὐμετάδοτον, which may be rendered “have perfected their readiness to distribute,” has the best manuscript authority, but it is barely intelligible; and the Benedictine Editors are quite right in calling attention to the fact that the point in question here is not the readiness of the flock to distribute (cf. 1 Tim. vi. 18), but their patient following of their Master.  The Benedictine Editors boldly propose to introduce a word of no authority τὸ ἀμετάβολον, rendering qui per patientiam animam immutabilem præbuerunt.  The reading adopted above is supported by a passage in Ep. 244, where St. Basil is speaking of the waywardness of Eustathius, and seems to fit in best with the application of the passage to the words of our Lord, “have fled for refuge to his ruling care,” corresponding with “the sheep follow him, for they know his voice” (St. John x. 4), and “have mended their wayward ways,” with “a stranger will they not follow,” v. 5.  Mr. Johnston, in his valuable note, compares Origen’s teaching on the Names of our Lord.
