I suppose the most common objection other than the Orthodox belief about the Theotokos is the veneration of saints.
We don’t know why St George should be considered so special. We are to worship ONLY the three in one God., God, Jesus and the Holy Spirit.
Matt.4:10 Then Jesus saith unto him,” Get thee hence , Satan: for it is written: Thou shalt worship the Lord they God, and him only shalt thy serve.”
So, it comes that most people believe that the Orthodox Church teaches people to worship saints. That is aboslutely not the case. We give honor to saints as holy people who have served God. Just as God asks us to honor our parents, we should also honor our spiritual parents.
As for the objection: Why do you pray to saints? We ask them for their prayers for us. They are actively worshipping before the throne of God, and that includes prayer. Why would I want them to not pray for me? If someone asks you to pray for them, are you really going to refuse and tell them that since they have direct access to God, they can pray for themselves? It’s the same thing, the saints just happen to be dead, but they are much closer to God than we are, so that’s got to count for something.
