The real history of pirates

A somewhat sad analogy occurred to me the other day.  If a police officer or military personnel needed your vehicle, they could legally take it, for professional use.  But if anyone else did so, it would be theft and punishable, an act of piracy.
A type of piracy has been going on for almost 2000 years now.  Every time someone who is not part of the historic church but claims to be so, is in essence stealing an identity.
Many of the seven ecumenical councils were held in response to various groups trying to redefine Christianity and take the name "Christian".
The Roman Catholics did this, officially in 1054.  The Protestants in Germany and Switzerland did so as well around 1550.  Again, the Anglicans around 1650.  The Mormons did so as well in the late 1800's.  In each of these cases, these groups rejected the historic Orthodox church and tried to exist independently.  This is similar to a severed limb trying to live apart from its body.  An appendage cut off from the rest of the body, is not the body.
A point of clarity is very important here.  This situation is about organizations and groups, not the individuals therein. As Orthodox Christians, we must never judge anyone or claim to know their heart. Only God is the judge.  What we can do though is identify the boundaries of the body of Christ.  The Orthodox church has the historic faith, we have the teaching of the apostles,  we have the guidance of the Holy Spirit.
So we can play the part of the pirate and steal an identity. Or we can embrace the faith once delivered to the saints and be part of the body of Christ.  Why would we do otherwise?
