The Church Why Bother?
This is a great article defending the necessity of church attendance for believers. One of the sentences which caught my attention was:
I would call it Gnostic faith. For them the spirit is completely separated from the body. They think your spirit can be with Jesus Christ while your body goes its own way.
In other words, people are believing more and more that they can be spiritual islands separated from the body of Christ. It is definitely worth a read.
