Reading edition
‘Est itaque ignis et dies, clara inspectio, certa probatio, perspicua revelatio, qua tandem cognoscemus doctrinarum veritatem, earum denique fallaciam.’—Petri Martyris Loci Communes: de Purgatorio Igne. These may not be the exact words used by Peter Martyr in his sermon, but the sense was the same.
