The Ancient Church is the Orthodox Church. The history of The Church is intertwined with Holy Scripture, Holy Tradition and the lives of the Saints, Martyrs and Fathers of the Ancient Church. The following links are well supplied with articles and audio lectures for your further study of Our Lord's Bride, His Church.
The Orthodox Church is evangelical, but not Protestant. It is Orthodox, but not Jewish. It is Catholic, but not Roman. It isn't non-denominational - it is pre-denominational. It has believed, taught, preserved, defended and died for the Faith of the Apostles since the Day of Pentecost over 2000 years ago. The Church exists to worship the Holy Trinity, to preach the Gospel to our community, and to transfigure the lives of her children into the likeness of Jesus Christ.
