Two longtime close friends of mine left the CoG for Eastern Orthodoxy back in the 1990s. I will say it is better than the Roman Catholic Church, in my opinion, and if I were ever to join a 'high church' tradition, I would definitely be much more inclined to join the EO than the RCC or Anglican Church. The issues are much the same with all of these high church traditions, in my view: 'Holy Tradition' over Scripture, prayers to Mary and other departed saints, sacramentalism, sacerdotalism, apostolic successionism, and so forth. The EO do seem to have the most beautiful iconography and architecture in their churches. They do insist, like Catholics, that they are THE original New Testament Church, but they generally do accept the fact that there may be real Christians in other Christian traditions.A good article on EO by a Protestant scholar who has specialized in the study of EO may be found at the following link: www.christianitytoday.com/ct/1997/january6/7t1032.html
