Upon entering the priesthood, Borrás was assigned to the Hieronymite Monastery of Saint Jerome of Cotalba in Gandia, where he painted the greater altarpiece of the church.

Three years later, Borrás spent some time with the Capuchins at the Franciscan monastery of San Juan de Ribera, near Valencia.

Borrás painted twelve altar pieces in the Monastery of Saint Jerome, as well as hiring sculptors and builders for its embellishment.

His paintings appeared in Saint Mary of Valencia Cathedral and at the Hieronymite monastery in the city of San Miguel de los Reyes where there was a "Christ at the Column", and a picture of the painter in adoration of "The Holy Virgin".

Among them are The Last Supper, Christ Bearing His Cross, The Dead Saviour in the Arms of the Eternal Father, and The Archangel Michael Driving Souls into Purgatory and Hell.
