Manuil Mykhailo Olsavszky

Manuil Mykhaylo Olshavskyi, O.S.B.M., (born as Michal Židik; , , , c. 1700 – 5 November 1767) was the bishop of the Vicariate Apostolic for the Ruthenians in Mukacheve from 1743 to his death in 1767.

Life Mykhaylo Olshavskyi was born in about 1700 in the village of Oľšavica, from which he took his surname (which originally was Židik). He studied philosophy in Košice and then in the Jesuit college of Trnava. At the end of his studies, he was ordained a secular priest in 1725 and assigned to the Eparchy of Mukacheve, where he later became vicar of the eparchs (bishops) Stefan Olshavskyi (who was his older brother) and Havryil Blazhovskyi.

At the death of his predecessor, he was appointed on 8 February 1743 as vicar general by the Latin Bishop of Eger: as at that time, following the Union of Uzhhorod, the eparch of Mukacheve was formally an apostolic vicar of the Latin diocese. In a few months he was elected to the position by the clergy, designated by the Empress Maria Theresa, and so confirmed by Pope Benedict XIV on 5 September 1743. He received the titular see of Rhosus and was consecrated bishop on 9 December 1743 by the bishop of Făgăraş, Inocenţiu Micu-Klein. A short time before consecration, Mykhaylo Olshavskyi entered the Order of Saint Basil the Great and took the religious name of Manuil. He again returned to Transylvania in 1761 to address, with his authority and predication, the disturbance fomented by the Orthodox monk Sofronie.
