 By 1967, Bishop Elko's popularity within his own Church waned, and his authoritative management style agitated many priests and laity.The Vatican transferred Elko to Rome, where he was elevated to the dignity of an Archbishop and appointed as the ordaining prelate for the Byzantine Catholics in Rome and head of the Ecumenical Commission on the Liturgy.This prompted his resignation as Byzantine Catholic Bishop of Pittsburgh, and Monsignor Edward V. Rosack, the Chancellor of the Eparchy, was named as the temporary apostolic administrator.
