I would suggest that you read Father Peter Gilquist's book Becoming Orthodox: A Journey to the Ancient Christian Faith . It has been reviewed as follows "Peter Gillquist is a first-person account of the spiritual journey of a group of evangelical Christians over a period of fifteen years to their reception into the Antiochian Orthodox Church. Many of them had been involved in Campus Crusade for Christ during the sixties and had remained in contact with each other during the seventies as they founded churches around the US. They agreed to study Church history to find out what the original New Testament Churches practiced. They noted from early Christian documents such as the writings of the Church Fathers that the Church had Bishops (ordained by the Apostles themselves), a hierarchial structure, Tradition, liturgical worship, communion as the literal Body and Blood of Christ, inscense, icons, the use of "Father" in addressing Priests, the veneration of the Virgin Mary as Theotokos ("God-bearer") and the Sign of the Cross. In examining the Schism of the Church in 1054 between Rome and the East, Gillquist and his fellow pastors acknowledged that Rome had erred in its Papal claims of universal authority over the Church, and the Western alteration of the Creed which originally stated that the Holy Spirit only proceeded from the Father, when now the Roman Catholic Church teaches that the Spirit proceeds from the Father and the Son (known as the "Filioque"). Gillquist and his affiliated group of churches, which they had labeled the Evangelical Orthodox Church, sought to join one of the Orthodox Churches in America. They were unsuccessful in meeting with the Patriarch of Constantinople, but they were reviewed and accepted by the Patriarch of Antioch and the Antiochian Archdiocese in North America."

The book has spoken to many protsetants who have just discovered the Orthodox Church, like yourself they seem to have these same discussions in their meetings that eventually led the majority of them to enter the Holy Orthodox Church.
