As this is called open church. I thought that a little bible study would be good
.
The Church is the Called Out Body
The word "church" is translated from the Greek work ekklesia, denoting a called out body of people.

God calls us out of the world of sin through the gospel (2 Th. 1:14). The church is composed of people who respond to God's call.

The word church is used in two ways. "Church" can be used in reference to all Christians, or a specific congregation. Jesus uses "church" both ways:

In Matt. 16:18, Jesus promises to build His church, speaking of Christians everywhere who would respond to the gospel call.
In Matt. 18:17, Jesus uses the word "church" regarding Christians in a local congregation.
