In the 18th century the deanery of Mościska belonged to the medium-sized deaneries of the Uniate Eparchy of Przemyśl. It covered an area of 18 km2, which did not differ from the average decanate. It consisted of 48 villages grouped into 37 parishes. The territory was inhabited by about 27,000 people, 59.3% of whom were Catholics of the Byzantine rite. Only 15.6% of the total population lived in the three towns (Husakovo, Krukienice and Mościska), which indicates the moderate urbanisation of the area. The Orthodox churches were the centre of religious life. They were probably founded by all believers. However, the church in Krukienice was founded at the expense of a local citizen, a certain Szwedzik. The Orthodox church in Mościsko, on the other hand, was built in 1611 after Jan Szczęsny Herburt, Starosta of Wichońsk and Mościska, signed a building permit on 12 January 1604. The state of the town's churches in 1769 prompted the inspector to make a comment. He noted that the church in Husakov and especially the lower church in Krukienice needed the most urgent repairs. The upper churches in Krukienice and Mosciska had to be renovated with less effort on the part of the faithful. The neglect of the Orthodox church by the parishioners was no accident, and in the lower part of Krukienice it forced the dean to issue a ban in 1773, which proved effective, as the building was finally properly renovated a year later. The endowment of the parishes in the Mościce deanery usually consisted of various church revenues. The parishioners of Husakov and two parts of Krukienice each had a quarter of a wheat field, those of Mosciska two quarters. In the second half of the 18th century, the urban parishes of the Mosciska deanery did not differ much from the pastoral centres in the neighbouring countryside. With a relatively small agricultural area and a moderate income for their beneficiaries, they were among the average parishes. Similarly, their priests were never portrayed as prominent figures or leading reprehensible lifestyles. The urban parishes of the gwemorat were thus typical Unitarian communities in the eastern part of the Przemyśl eparchy.
