What would a church (say a mainline protestant evangelical church) have to believe and do in order to come under Eastern Orthodox Church?

    Presumably it would have to stop being a Protestant church and become an Orthodox church instead. That would start with repudiating the signature Protestant doctrines of justification by faith alone and penal substitution, not to mention the whole satisfaction theory of atonement, which is not held to in the Eastern church.

  • Would there be any sacramental/liturgical or ordination requirements in addition to confessing EOC doctrines?

  • Really, it's highly unlikely that any Protestant church would want to become an Orthodox church. It would mean becoming an entirely different church. And churches tend to hold tightly to their beliefs and traditions. However, if by some strange stretch of the imagination a Protestant church actually wanted to do this, it would need to talk to the body of Orthodox Christianity that it was interested in joining, and go through whatever process of conversion was necessary.

  • Based on my studies, the EO tends to go easy on people, but naturally the different EO jurisdictions don't have a uniform policy. But typically, if a Protestant is going in this direction they basically almost certainly have done lots of study to be able to feel comfortable with such a radical move. So most of the time the initial training is on the hands on sacramental side. Commented Apr 23, 2018 at 15:36
  • But there might be something where they would arrange study at saint Vladimir's Seminary (in the US) later. Commented Apr 23, 2018 at 15:37

This has only happened on one occasion. If you read the Book "Becoming Orthodox" It tells the story of a group of Campus Crusade for Christ ministers who formed their own denomination after graduating college, eventually calling themselves the Evangelical Orthodox Church. That group went on a quest "to discover the doctrine of the Early church", which eventually led them to investigate Eastern Orthodoxy. Most of the churches in their group converted but a few did not and remained independent. This sort of thing has happened in a few other cases to individual churches, I can cite stories where a Vineyard (Charismatic) church and a Four-Square Church have converted to become EO parishes.

While this is unlikely to happen (due to the vast differences between most Protestants and the Eastern Orthodox) it is possible. All that is needed is for the church group to show an interest in learning and adopting the Holy Tradition (of the EO) and a Metropolitan, Patriarch or Bishop that is willing to shepherd them into joining his jurisdiction. I recommend the following link on the conversion of the Evangelical Orthodox Church.

Retrospective on the EOC Reception into the Antiochian Orthodox Christian Archdiocese

"We arrived at the Antiochian Orthodox Christian Archdiocese headquarters in Englewood, New Jersey, and the moment the door opened I knew my life would change forever. “Welcome home,” burst from Sayedna’s lips after we, the delegation representing the Evangelical Orthodox Church, accepted his gracious offer to receive our parishes — about 2,000 Evangelical Protestants across North America — en masse into the Orthodox Church. Metropolitan PHILIP’s two beautiful words still reverberate in my mind and heart 20 years later, and surely will for the rest of my life. His Eminence put a lot on the line in receiving the Evangelical Orthodox Church (EOC). But he took that risk believing it was the right thing to do, and expecting that God would use this move to bless the members of the former EOC as well as all the Orthodox Christians of North America, and through them eventually all the people of our continent. God has been gracious, abundantly pouring out His blessings since Sayedna received the EOC into the Antiochian Archdiocese in 1987. I would like to review four prominent areas in which God has worked: the Orthodox Study Bible, the Orthodox Conference on Missions and Evangelism, the planting of over 100 new missions, and the revival of Orthodox campus ministry."


Here also are two articles of churches from a Pentecostal and Charismatic background that became Eastern Orthodox.



  • Good answer, but can you provide some references to where these church conversions are documented? Commented Apr 20, 2018 at 15:38
  • Sure I can supply some web links and maybe a few quotes Commented Apr 20, 2018 at 16:38
  • Very helpful, thank you. What I was really getting at (the question behind the question) was how much the EOC is a tight denomination or looser doctrinally bound confederation of churches, and how much liturgical freedom there is within it. A local priest told a friend it's totally possible for my church to be accepted into the EOC, and I got the impression it would require more a confirmation of Orthodox belief than many changes in forms of worship (though of course liturgy is v important as a participation in grace).

  • @AidanAshby, the "Evangelical Orthodox" Pavel refers to were already practicing largely Orthodox forms of worship. For them, becoming part of the Orthodox Church definitely wasn't a matter of joining an umbrella organization while continuing to do whatever they liked. In fact, some ten years later, there was a crisis in a Ben Lomond, CA parish due to, one side might say, imperious behavior by Orthodox bishops...but the other side would say it was due to the failure of that parish to submit to its overseers as every Orthodox parish must.
