He entered in the Capuchin order and he moved to the convent of the Sarrià Capuchins. He got his degree in History in the Catholic university of Louvain, and since 1926 he was the director of the review Estudis Franciscans. In 1924 he published Jaume Caresmar's Història de la primacia de la seu de Tarragona. He became specialized in Francesc Eiximenis, and he transcribed the Doctrina compendiosa in 1929, which in fact, as it was later proven, is attributed to Francesc Eiximenis, and even though the book is inspired by his thought and doctrines, it was not written directly by him. Together with the Capuchins Norbert d'Ordal and Feliu de Tarragona, they transcribed also three hundred fifty-two chapters of the Terç from Lo Crestià. He also transcribed his interesting Ars Praedicandi Populo, that was discovered by him in Krakow. Moreover, he wrote several articles about medieval Catalan society and culture. He was murdered by the FAI's anarchistsat the beginning of the Spanish Civil War. He was beatified in the cathedral of Barcelona on 21 November 2015 together with other Capuchins that had been also murdered during the religious persecution of 1936.
