Why are some of these not churches?

[Conservativegreatgrandma]

They are left wing political organizations. They are not there to save souls, they are there to promote a liberal political agenda.

A church isn't interested in your salvation unless it is teaching directly from the Bible. Try this:

Hold your Bible with the spine toward the floor. Think of the front cover & back cover of the Bible as the rails - like a railroad track. If what you are taught is between the rails, it is of God. If you are being taught things that fall outside the rails, it is of man. Jesus is the only one who can give you everlasting life. If a man tells you he can you are being deceived.

Many of the churches in the list are teaching nothing from the Word or they take a little piece of the Word, muck it up with man and then teach it as gospel. The more of His word that you know, the less likely you will be cheated out of salvation.
