“_To the most excellent lord, our son, Oswy, king of the __ Saxons, Vitalian,_(_501_)_ bishop, servant of the servants of God._ We have received to our comfort your Excellency’s letters; by reading whereof we are acquainted with your most pious devotion and fervent love of the blessed life; and know that by the protecting hand of God you have been converted to the true and Apostolic faith, in hope that even as you reign in your own nation, so you may hereafter reign with Christ. Blessed be the nation, therefore, that has been found worthy to have as its king one so wise and a worshipper of God; forasmuch as he is not himself alone a worshipper of God, but also studies day and night the conversion of all his subjects to the Catholic and Apostolic faith, to the redemption of his own soul. Who would not rejoice at hearing such glad tidings? Who would not exult and be joyful at these good works? For your nation has believed in Christ the Almighty God, according to the words of the Divine prophets, as it is written in Isaiah, ‘In that day there shall be a root of Jesse, which shall stand for an ensign of the people; to it shall the Gentiles seek.’(502) And again, ‘Listen, O isles, unto me, and hearken ye people from far.’(503) And a little after, ‘It is a light thing that thou shouldst be my servant to raise up the tribes of Jacob, and to restore the outcast of Israel.

Wherefore it behoves your Highness, as being a member of Christ, in all things continually to follow the pious rule of the chief of the Apostles, in celebrating Easter, and in all things delivered by the holy Apostles, Peter and Paul, whose doctrine daily enlightens the hearts of believers, even as the two lights of heaven illumine the world.” And after some lines, wherein he speaks of celebrating the true Easter uniformly throughout all the world,—
