Which is more important ? the bible or the church ?

The Bible because it is the inspired word of God (2 Timothy 3:16,17). You may not always have the church and there are so many different religions that teach many different things, but there is only one truth...a lot of religions mislead and teach untruths to the detriment of their followers. The church should be formed and teach things around what the Bible teaches, not tradition or what the people want to hear.
