In September 18, 1981, it was established as the Ordinariate of Poland for Byzantine Rite and Armenian Catholics by Pope John Paul II.
[citation needed] On 16 January 1991, following the erection of two Ukrainian Greek Catholic eparchies, the ordinariate assumed its current name and limited its jurisdiction.
[citation needed] As of 2007[update], 147 faithful of the Catholic Church of the Byzantine Catholics who belonged to a parish of Kostomłoty were entrusted to the pastoral care of the Latin Bishop of Siedlce.
[1] Since Archbishop Nycz's decree on 1 December 2009, the ordinariate maintained jurisdiction over three churches, all for Armenian Catholics.
[2] The ordinariate is exempt, directly dependent on the Holy See (not part of any ecclesiastical province and the Roman Congregation for the Oriental Churches).
