Register to reserve a seatAbout the Conference
The Council of Nicaea (325 CE) stands as one of the most significant events in Christian history, convening bishops to unify doctrine and address heresies. This event commemorates the 1700th anniversary of the council, highlighting its enduring legacy and profound impact on Christianity.
The celebration aims to revive the values of unity and shared faith advocated by the Council, while highlighting its significance in the modern era.
The Meaning of the Conference Logo: The tree represents man in the Bible, and a tree is known by its fruits. The Church is a group of believers who have their own historical, cultural, and apostolic dimensions in evangelism and pluralism. This is expressed through the alphabet and the letter Omega, according to each Church’s language, and embodied by the cross, which is Christ in His true person, expressing Christianity through His salvific sign.
The cross and the circular shape of it symbolize perfection, as the circle is a symbol of perfection that every earthly Church seeks to achieve through its evangelistic mission. The tree has roots, and these express the continuity and power of life that is nourished by their extension. This is the conference’s depth of faith, as it unites us, the Christian Churches, through our roots, and as we are all nourished by the person of Christ Himself.
The sun symbolizes the eschatological dimension of the entire Christian Church. It symbolizes the East in the geographical sense and in terms of the orientation toward the East in our Eastern rituals, meaning the second coming of Christ and the point of meeting with Him from the East, according to the Bible. Its light is that of Christ, which shines upon His universal Church, as He is the light of the world.
