Abstract

The Second Vatican Council, taking into account the modern needs of mankind, called for the mutual tolerance of denominations, reforms and compromise in church traditions and practices. This was a response to the practical life of the Ukrainian church in the diaspora. For the Eastern Churches, the Council adopted a separate Decree "The Constitution for the Eastern Churches" 1, on the basis of which a conference of the UCP bishopric, led by the Supreme Archbishop Joseph Slipy, was convened on December 14, 1966 in Rome. It discussed a number of issues, including the case of Divine Liturgy, the liturgical language, the introduction of the Ukrainian spoken language, some reductions in the Service of God, and the reformation of church singing. It was for this purpose that the dioceses established Liturgical Commissions, in particular at the Chicago Department in the United States, which included the musicologist, composer, and musical culture activist of the Diaspora Myron Fedorov. One of the tasks of the commission was to preserve the traditional self-made singing, so that he "did not disappear, but he lived and developed under different kinds: single-handed, double-voiced or in choral works, which most would be out of the richness and beauty of our rite"
