Bishop Mihalik endeavored to establish more churches in the outer-most parts of his eparchy in places such as Las Vegas, NV, Albuquerque, NM, and Denver, CO. The growth of these Western missions and churches was acknowledged by Pope John Paul II through the erection of a fourth jurisdiction for Byzantine Catholics: the Eparchy of Van Nuys, CA; and, through the selection of Bishop Thomas V. Dolinay (then Auxiliary Eparch of Passaic) as its first eparch. He shepherded the eparchy from his seat at Holy Protection of the Mother of God Cathedral in Van Nuys until he was chosen, in 1991, to be Metropolitan of Pittsburgh, succeeding the ailing former shepherd, Archbishop Stephen J. Kocisko.
Consequently, the auxiliary eparch of Passaic, Bishop George Kuzma, was enthroned as the second Eparch of Van Nuys, and, in 1997, moved his seat of administration to Saint Stephen Protomartyr Pro-Cathedral in Phoenix, AZ. In 1996, Bishop Michael J. Dudick retired after a long and pastorally beneficial ministry in the Eparchy of Passaic. Upon his retirement, the Holy Father appointed Bishop Andrew Pataki (formerly Eparch of Parma), as the third Eparch of Passaic.
The spiritual life of the Byzantine Catholic Church was and continues to grow with assistance not only from the Basilians of Uniontown, but also from Monasteries for men and women, such as The Basilian Fathers of Mariapoch, Matawan, NJ, as well as from Holy Dormition Franciscan Monastery, Sybertsville, PA. In addition to monasteries and convents, the Eparchy of Passaic possesses parochial schools and academies to teach the Gospel and to promote authentic Christian morality in an Eastern experience. Academic institutions are located in the communities of Saint Mary's, Wilkes Barre, PA, and Saint Mary's, Trenton, NJ.
