"Crede quod habes"

The celebrated answer to a Protestant about the real presence, by the borrower of his horse, is supposed to be made since the Reformation, by whom I forget:— "Quod nuper dixisti De corpore Christi Crede quod edis et edis; Sic tibi rescribo De tuo palfrido Crede quod habes et habes." But in Wright and Halliwell's *Reliquiæ Antiquæ*, p. 287., from a manuscript of the time of Henry VII., is given— "Tu dixisti de corpore Christi, crede et habes De palefrido sic tibi scribo, crede et habes."
