Christianity expanded from Cebu when the remaining Spanish missionaries were forced westwards due to conflict with the Portuguese, and laid the foundations of the Christian community in the Panay between around 1560 to 1571. A year later the second batch of missionaries reached Cebu. The island became the ecclesiastical "seat" and the center for evangelization. Missionary Fray Alfonso Jimenez travelled into the Camarines region through the islands of Masbate, Leyte, Samar, and Burias and centered the church on Naga City. He was named the first apostle of the region. By 1571 Fray Herrera, who was assigned as chaplain of Legazpi, advanced further north from Panay and founded the local Church community in Manila. Herrera travelled further in the Espiritu Santo and shipwrecked in Catanduanes, where he died attempting to convert the natives. In 1572, the Spaniards led by Juan de Salcedo marched north from Manila with the second batch of Augustinian missionaries and pioneered the evangelization in the Ilocos (starting with Vigan) and the Cagayan regions.
