After joining the clergy, he was the interim priest of Coaza (Carabaya), and for five years he was the head of doctrine in the district of Pachaconas (Antabamba).

He graduated with a doctorate in 1808, was named the synodal examiner of the bishopric and general visitor of six provinces, and was assigned to the parish of Soraya (Aymaraes), in 1810.

At the beginning of the Cuzco Rebellion of 1814 led by Brigadier Mateo Pumacahua, he gave his assets to the cause, although when the royal authority was restored, they were set on fire by order of Colonel Vicente González.

In January 1825 he was part of the Qualification Board established in Cusco by Simón Bolívar to distribute jobs among citizens qualified by their integrity, ability and service.

In his last years he wrote his memoirs and documented his family archives, ultimately publishing "Memories of the Peruvian Monarchy or outline of the history of the Incas" (Paris, 1850).
