Born in Ascó in 1680, he joined the Dominican Order in 1697 and was ordained a priest in 1704. After spending two years in the Philippines learning Chinese, he began a ministry in China that spanned more than three decades. He eventually served as the Vicar Apostolic of Fujian, having been consecrated a bishop in 1730.
