[5] On September 1 of that year, he signed a protest against the appointment of Józef Bakowiecki-Mokosiej to the bishop's position in Volodymyr, officially due to the violation of the election procedure.

[9] The pacta conventa of King Władysław IV imposed on the monarch the obligation to restore the structures of the Orthodox Church within the Polish–Lithuanian Commonwealth.

For the Przemyśl eparchy, it was decided to transfer the bishopric to the Orthodox faithful after the death of the Uniate bishop, Alexander Krupecki.

[16] The Uniate bishop Athanasius Krupecki disagreed with the parliamentary decisions, and his supporter, the Przemyśl starosta Jan Mikołaj Daniłowicz, refused to grant Hulevych control over the monasteries.

This group arrived on 10 June 1636 at the Wilich church near Przemyśl, where Hulevych established his base and gathered additional anti-union forces from all estates.

He argued that the royal diploma was issued under a peace seal and was therefore invalid, and that he had a document granting him lifetime control of the monasteries.

Although his life was spared due to Hulevych's intervention,[5] the Uniate bishop was subjected to numerous insults and spent two days imprisoned in the monastery's underground, starving.

[12][16][18][19] In response to the armed seizure of the monasteries, Athanasius Krupecki filed lawsuits against the attackers in the Przemyśl municipal court (24 June 1636), the Crown Tribunal in Lublin, and in Piotrków Trybunalski.

[16][20] He also launched a broad propaganda campaign, resulting in demands for the "contentment" of the Uniate bishop in the instructions of the Proszowice, Środa, Opatów, Wiszeński, and Bełz courts for the Sejm of 1637.

The prepared constitution Greek Religion absolved the disunites from responsibility for the armed conflicts, but the matter of redistributing properties in the Przemyśl diocese was postponed to the next Sejm.

[21] Just ten days later, the Piotrków Crown Tribunal imposed infamy on Bishop Sylvester[a] and several dozen of his supporters,[b] depriving Hulevych of his ability to perform clerical duties.

[23] Disunite deputies requested the annulment of the infamy verdict at the extraordinary Sejm on 9 June 1637, but they failed to convince the other chamber members.

Conversely, the Środa, Opatów, and general Ruthenian courts (the latter with a protest from the Orthodox nobility) demanded the enforcement of the verdicts.

[26] Two weeks later, Władysław IV managed to pass the Greek Religion constitution, restoring the legal status established in 1635.

The king presented further proposals at the senate session on September 29, deciding to annul the verdict against Hulevych, opposed only by Albrycht Stanisław Radziwiłł.

[38] Efforts to restore the bishop's favor were made by Orthodox deputies at the Sejm on 16 March 1645, but their proposals were not discussed in the session.
