Greek Patriarchate of Constantinople

The Greek Patriarchate of Constantinople is a leading jurisdiction within Eastern Orthodoxy, serving as the spiritual and administrative center for Greek Orthodox Christians in Istanbul and surrounding regions. It is led by the Ecumenical Patriarch, considered "first among equals" among Orthodox bishops worldwide. While it has religious authority over its dedicated community, it operates within the broader framework of the Eastern Orthodox Church, which is a communion of autocephalous (independent) churches. The Patriarchate also plays a significant diplomatic and cultural role, preserving traditions, promoting Orthodox unity, and maintaining historical ties to the Greek heritage of Constantinople (modern-day Istanbul).
