But they did not only pray for others, they were careful to secure for themselves, after their departure, the prayers of their friends. This they frequently solicited as a favor or recompense, and for this they entered into mutual compacts by which the survivor was bound to perform certain works of piety or charity for the soul of the deceased. Thus Beda begs of the monks of Lindisfarne that, at his death, they will offer prayers and Masses for him as one of their own body; thus Alcuin calls upon his former scholars at York to remember him in their prayers when it shall please God to withdraw him from this world; and thus in the multifarious correspondence of St. Boniface, the apostle of Germany, and of Lullus, his successor in the See of Mentz, both of them Anglo-Saxons, with their countrymen, prelates, abbots, thanes, and princes, we meet with letters the only object of which is to renew their previous engagements, and to transmit the names of their defunct associates. It is "our earnest wish," say the King of Kent and the Bishop of Rochester in their common letter to Lullus, "to recommend ourselves and our dearest relatives to your piety, that by your prayers we may be protected till we come to that life which knows no end. For what have we to do on earth but faithfully to exercise charity towards each other? Let us then agree, that when any among us enter the path which leads to another life (may it be a life of happiness), the survivors shall, by their alms and sacrifices, endeavor to assist him in his journey. We have sent you the names of our deceased relations, Irmige, Vorththry, and Dulicha, virgins dedicated to God, and beg that you will remember them in your prayers and oblations. On a similar occasion we will prove our gratitude by imitating your charity."
