In 1756, he finished the construction of the Makarska Cathedral and built the Church of St. Philip Neri in 1757 and a building for the Oratorians (which burnt down on 20 September 1766).
[1] Based on the traditional right as the bishop of Makarska,[3] Blašković also administered the Diocese of Duvno under the Ottoman occupation, which he visited during Jul and August 1735.
While in the Duvanjsko Polje, Blašković met with the Muslim beys of the Kopčić family, which was present during the Catholic ceremonies and asked him for prayers and relics.
To prevent further exodus of the Catholic serfs and return those who fled, the beys asked Blašković to reside in Rama, promising him the Franciscan possessions and a pay of 300 sequins and additional means for maintenance.
The Congregation accepted this initiative and on 20 June 1735, asked the pope to appoint a special bishop for the Catholics under the Ottoman occupation, and that he should be from the ranks of the Bosnian Franciscans.
[6] Blašković published the translation of Robert Bellarmine's catechism under the title Nauk kršćanski (The Christian teaching) in Venice in 1758.
