Heresies of the Orthodox Church.
While the Orthodox Church claims to be grounded in tradition tracing back to the Apostolic Fathers, it has deviated from the unified teachings of the Early Church and the Church Fathers of the first 300 years in various ways. They believe in lies that these Church Fathers condemned, thus making it heretical.
These are all the Heresies listed… and those are also the reason we could never be a part of the Orthodox Church:
Worshipping images
Praying to the dead
Worshipping Mary
Approving divorce and remarriage
False ordinations of priests
Love of money and luxury
Immodest dress
Teaching of Evolution
Neglecting holy kiss
Long hair on priests
Meaningless repetition of prayer
Souls going to Heaven
1000 year reign
Condemnation of early church
Condoning post-Nicaea sins
Approving War
PS: their support of War contradicts the teachings of the early Church in a big way.
