The best way to prove you are a true Orthodox Church is not by offering public apologetics, historical ecclesiastical tracking, and attempting to discern the heart and intent of the actions of jurisdictional Bishops at a moment in time, so that you might compare yourself to them, saying,
"I thank thee, oh God, that we are not like that Jurisdiction over there!"
Rather, the best way to show you are a true Orthodox Church is to be filled with the Holy Spirit of God thus exhibiting the fruits of the Spirit and the dunamis power of ministry.
"By their fruits you shall know them."
In this way the presence of God among you will be noised abroad.
The lack of such demonstration is to
"Have a form of Godliness but deny the power thereof,"
thus proving you are not a true Orthodox Church.
