In his book, Three Witnesses for the Baptists, Page 93, Bro. Curtis Pugh makes the following and absolutely correct statement. In this statement by Bro. An ecclesia is only and always an organized body. There is no such thing as an ecclesia that is not organized.
Organization is inherent in the word.
Two or more groups of scripturally baptized believers regularly assembling in two or more places cannot be properly and scripturally called an ecclesia, or one church. Our correspondent will do well to keep in mind these three essential ideas inherent in the word ecclesia. These folks were not meeting in secret, but were observed for their boldness in openly declaring the gospel of Jesus Christ. Reading this passage, it appears they were all assembling together. When Peter and John were released from prison by an angel, he commanded them to go into the temple and preach.
