When his elder brother Diosdado visited and saw Camomot was not attending school, he asked him if he wanted to enter the seminary.

On 25 March 1955, Camomot was appointed auxiliary bishop of Jaro, Iloilo, receiving episcopal ordination on 29 May 1955 and staying until 1959.

He formed the Paulinian Faith Defenders and the Carmelite Tertiaries of the Blessed Eucharist, the predecessor organisation of the Daughters of Saint Teresa.

Camomot was neither an eloquent preacher nor a convincing speaker, but was noted for spending hours in the confessional, waking up very early for Lauds and meditation, and works of mercy.

Cebu archbishop emeritus Ricardo Jamin Vidal said there were several reports of Camomot's bilocation as people would see him in two places at the same time.

Vidal signed an affidavit in relation to an eyewitness account on this phenomenon, where Camomot was drowsing beside him at a meeting of the College of Consultors.
