[1] On June 29, 1587, Father Juan Bautista de Montoya was appointed as prior of Purao with the Augustinians accepting the convent to their order.

It was annexed to Namacpacan in 1739 and the name of the town of Purao was changed to what is known today as Balaoan.

Father Juan Antonio Fernandez continued the construction by extending the church from the presbytery to the main entrance from his appointment to Balaoan in 1769 until his death in 1829.

Father Valentin Noval continued the work on the church when he was appointed in 1839.

Although the church underwent major renovations, it has retained its original foundation and designs.
