An Ecclesia is a group sent by a government to change the people of a region owned by the government. This would cause the people to live like loyal subjects of the government. When the Romans did this, the Ecclesia Romanized the people they were sent to.
As a body of believers, we are to change the world by making "disciples of all nations, baptizing them in the name of the Father, the Son, and the Holy Spirit." This is our commision. Here at Ecclesia of Jesus Wikia, we inform other believers of their mission from the King and prepare them for it.
