In December 2020, Supreme Archbishop Svyatoslav stated that the Greek Catholic Church would address the calendar transition together with Orthodox counterparts, emphasizing that this is not a doctrinal issue but aims to heal church divisions. He suggested that the shift to celebrating Christmas on December 25 should be initiated by the laity. In December 2022, Svyatoslav and Metropolitan Epifaniy discussed calendar reform and established a joint working group to explore the issue, marking the 1700th anniversary of the First Ecumenical Council.
