Brief and fragmentary as are the phrases that record it, we can gather that he came back with a sort of horror of that outer world, in which there blew such wild winds of doctrine, and a longing for the inner world which any Catholic can share, and in which the saint is not cut off from the simple men. He resumed the strict routine of religion, and for some time said nothing to anybody.
And then something happened (it is said while he was celebrating Mass), the nature of which will never be known among mortal men.
His friend Reginald asked him to return also to his equally regular habits of reading and writing, and following the controversies of the hour. He said with a singular emphasis, “I can write no more.” There seems to have been a silence; after which Reginald again ventured to approach the subject; and Thomas answered him with even greater vigor, “I can write no more. I have seen things which make all my writings like straw.”
