Having entered the Dominican Order and completed his studies at Salamanca, he was sent in 1625, together with many others, as a missionary to the Philippine Islands. Whilst serving as chaplain in a hospital for Chinese and Japanese at Manila he learned their languages.
In 1631 he offered to go to Japan and arrived at the outbreak of the persecution in 1632. Disguised as a bonze, he travelled over the land and administered the rites of the Catholic religion.
He was arrested 4 August, 1634, and subjected to tortures that lasted seven days. He was forced to witness the beheading of his companion, Thomas of St. Hyacinth, and sixty-nine other Christians. On 18 November he was suspended till dead from a plank with his head buried in the ground.
Whilst detained in Mexico, on his way to the Philippine Islands, he wrote in Latin a series of lives of Dominican saints after a similar work by Hernando del Castillo. He left at Manila an unfinished treatise on Chinese religion.
