One of the most influential church splits in history was the Great Schism between the Roman Catholic Church in Rome and the Orthodox Church in Constantinople in 1095. On May 7, 1274, the two groups met in Lyons, France, for the Second Council of Lyons and seemed to agree on the biggest issue: the dogma and language of the church creed about Jesus Christ as God’s Son. Even with five hundred delegates in attendance, the Orthodox Church ultimately rejected the Council’s agreement.
