[FRAGMENT OF A LETTER FROM ABBOT TAIO TO BISHOP BRAULIO]
...Such a religion is pious, to be sure, but to me it is questionable. Therefore, most holy of men, I bring this sort of query to your ears, and if it is definitely to be believed, as I have already said, that the Blood of the Lord remained with certain individuals after His Resurrection, I want to be informed by you with unimpeachable testimony and the surest proofs. I should like to receive a treatise on this matter from your generosity. The Lord Jesus Christ will furnish me a sure proof without ambiguity, if my prayers are fulfilled by you.
Follow the final salutations.
