Yes, but they are not precursors of the Ruthenian Catholic Church (the opposite is true, especially in the case of ACROD). The “mother Church” of the Ruthenians is the Eparchy of Mukachevo in the Zakarpatska Oblast of modern Ukraine. It traces its history back to the foundation of Christianity in the the Slavic lands by Sts. Cyril & Methodius, so it could be said that this Church was Orthodox from the beginning in that it would have been part of the Patriarchate of Constantinople. Being isolated from its hierarchical roots after the fall of Constantinople, it eventually reunited with Rome via the Union of Uzhhorod.The sister Orthodox Church to the Ruthenian Byzantine Church is the ACROD (American Carpatho-Rusyn Orthodox Diocese) under the Ecumenical Patriarch and also historically the OCA, although OCA is more Russian-leaning in praxis today.
