you sent the gentle bishop Aidan
to proclaim the gospel in this land:
grant us to live as he taught
in simplicity, humility, and love for the poor;
through Jesus Christ our Lord. Amen
FROM the aforesaid island, and college of monks, was Aidan sent to instruct the English nation in Christ, .... it was the highest commendation of his doctrine, with all men, that he taught no otherwise than he and his followers had lived; for he neither sought nor loved any thing of this world, but delighted in distributing immediately among the poor whatsoever was given him by the kings or rich men of the world. He was wont to traverse both town and country on foot, never on horseback, unless compelled by some urgent necessity; and wherever in his way he saw any, either rich or poor, he invited them, if infidels, to embrace the mystery of the faith or if they were believers, to strengthen them in the faith, and to stir them up by words and actions to alms and good works.
...... whatsoever gifts of money he received from the rich, he either distributed them, as has been said, to the use of the poor, or bestowed them in ransoming such as had been wrong. fully sold for slaves. Moreover, he afterwards made many of those he had ransomed his disciples, and after having taught and instructed them, advanced them to the order of priesthood.
...It is reported, that when King Oswald had asked a bishop of the Scots to administer the word of faith to him and his nation, there was first sent to him another man of more austere disposition, who, meeting with no success, and being unregarded by the English people, returned home, and in an assembly of the elders reported, that he had not been able to do any good to the nation he had been sent to preach to, because they were uncivilized men, and of a stubborn and barbarous disposition.
They, as is testified, in a great council seriously debated what was to be done, being desirous that the nation should receive the salvation it demanded, and grieving that they had not received the preacher sent to them.
Then said Aidan, who was also present in the council, to the priest then spoken of, "I am of opinion, brother, that you were more severe to your unlearned hearers than you ought to have been and did not at first, conformably to the apostolic rule, give them the milk of more easy doctrine, till being by degrees nourished with the word of God, they should be capable of greater perfection, and be able to practice God's sublimer precepts." Having heard these words, all present began diligently to weigh what he had said, and presently concluded, that he deserved to be made a bishop, and ought to be sent to instruct the incredulous and unlearned; since he was found to be endued with singular discretion, which is the mother of other virtues, and accordingly being ordained, they sent him to their friend, King Oswald, to preach; and he, as time proved, afterwards appeared to possess all other virtues, as well as the discretion for which he was before remarkable.
