Metropolitan Konstantinos of Singapore and South Asia was one of more than a hundred hierarchs of the Ecumenical Throne who signed the Act of Indiction, the Proclamation of a New Ecclesiastical Year, on Tuesday, September 1, 2015, following the Divine Liturgy at the Patriarchal Cathedral of Saint George at the Phanar, Constantinople. The hierarchs signed in order of seniority, beginning with His All-Holiness Ecumenical Patriarch Bartholomew and continuing from senior to junior, based on the date of consecration to the Holy Episcopacy.
