council · 787 · Nicaea
Under the empress Irene and patriarch Tarasius, about 350 bishops met at Nicaea in 787 to end the first iconoclasm. The Horos drew the decisive line: icons receive veneration (proskynesis), God alone worship (latreia), for the honour paid the image passes to the prototype. The seventh and last council both East and West count ecumenical.
The Second Council of Nicaea is recognized as the last of the first seven ecumenical councils by the Eastern Orthodox Church and the Catholic Church. In addition, it is also recognized as such by Old Catholics and others. Protestant opinions on it are varied.
The first iconoclasm: may the church make and venerate images of Christ and the saints?
Icons restored: veneration (proskynesis) passes to the prototype, worship (latreia) is God's alone; Hieria anathematized; 22 canons.
