Jerusalem — October 5, 2025. The Tantur Ecumenical Institute, together with the Focolare Movement and the Ecumenical Commission of the Catholic Church, and with the support of the Pontifical Mission and the Helen and Edward Mardigian Armenian Museum of Jerusalem of the Armenian Apostolic Patriarchate of Jerusalem, hosted an ecumenical concert commemorating the 1700th anniversary of the Council of Nicaea. The event was held at the Armenian Museum in Jerusalem, with more than 200 people in attendance.
Bringing together faithful and friends from across the city’s Christian communities, the program of sacred music and common prayer offered a living witness to the Nicene confession of faith and to the hope of visible Christian unity today.
Heartfelt thanks to the choirs who made this celebration possible: the Armenian Seminary of Jerusalem, the German Lutheran Church & Dormition Abbey, the Coptic Orthodox Church, the Syriac Orthodox and Syriac Catholic Churches, and the Greek Orthodox Church. Their voices, distinct yet harmonious, embodied the spirit of fellowship that the Council of 325 continues to inspire seventeen centuries later.
We are grateful to all who attended and to our partners and supporters whose collaboration made the evening possible. Your presence, and that of everyone who joined us, made the gathering truly unique. Thank you.
