Letter CCLXVII. To the Abbot of Cluny

Your son, Brother Gaucher, has also become ours according to the rule, All mine are thine, and thine are mine (S. John xvii. 10). Let him be not less loved because he is common to us both, but, if possible, let him be more loved and held in greater favour; as he is mine because yours, so let him be yours because mine.
