Devilish spirits hold their doctrines together. They are not of a divine origin, but man made. Bricks are something that man makes as a cheap, inferior substitute. We need to be ever reminded that behind every false teaching and every false doctrine is a spirit that propagates it. Those devilish spirits are out to seduce the souls of mankind.
Spirits hold the systems together and hold people to their doctrines and systems.
When it is truly God's church, a name does not have to be concocted. God had a city, but they would not accept His city. We found that verse 1 tells about the morning time, and verse 2 tells about the morning-time apostasy. Next, we see in the interluding verses what started to develop. This, in type, portrays the same truth that we see in Revelation, Chapter 13, when he talked about the people being of all one language, or one doctrine, and nothing being restrained from them.
