The Orthodox Church is THE church established by Jesus Christ as described in the New Testament.
- It is the pillar and foundation of truth (1 Tim 3:15)
- It contains the entire Apostolic faith once delivered to all the saints (Jude 3).
- When Christ established His Church, He said that the gates of Hades would not prevail against it (Matt 16:18)
- The Nicene-Constantinopolitan Creed, a creed established by Church ecumenical councils in 325/381 AD describe the church as One, Holy, Catholic, and Apostolic.
Protestant/Catholic churches do not fit any of the above criteria, as they were inventions 1000+ years after Christ established His Church.
