In 1693 he was ordained as priest, and in 1694 he was appointed as the rector of the Episcopal Seminary of Macerata, where he taught rhetoric.
He continued to collect historical material during the service in Jesuit colleges in Gorizia, Rijeka and Trieste, and during the missionary stay in Dalmatia (1709–1715).
[1] In 1716 he went to Venice, whence he was reassigned to the Jesuit college in Padua with the task of completing the ecclesiastical history of Illyricum.
In his work on collecting, studying and arranging the material he received help from the Archbishop of Split, Pacifico Bizza.
Until his death Riceputi has compiled a comprehensive introduction to Illyricum sacrum, and the work was completed by his colleagues Daniele Farlati and Giovanni Giacomo Coleti.
