The Diocese of San Jose lies in the northern part of Nueva Ecija. Evangelized by the Agustinian missionaries, Nueva Ecija was created as a province in 1705 by Spanish Governor Fausto Cruzal. The name of the province is attributed to Governor Cruzal, who chose this name after his hometown Ecija in Seville, Spain.
The Franciscan Fathers took over from the Agustinians and continued the work of evangelization. Later on, the diocesan clergy, helped by the Missionaries of the Sacred Heart, carried on the apostolate.
