The old testament, then the church and the new testament.
The early Church created the New Testament.
Jesus mentions 'the church' 18 times in the New Testament.
The Bible, in the New Testament, teaches that the Christian believers ARE the church. It states this many times. The idea of "church" meaning a building is a much more recent idea. At the beginning of the church there probably weren't any church buildings as such. So according to the Bible in the New Testament, Christian believers are part of the church, and the church is the body of Christian believers. The expectation of the New Testament is that Christian believers will be a part of the church, personally involved and in relationship with the other believers. The New Testament does not have anything to say about whether people who are not believing Christians should attend church - there's no rule about it. But there's no reason why they shouldn't. Most of the New Testament was written specifically to churches, not to individuals.
The Old Testament was a series of Laws. The New Testament is Love and Faith.
