I've never, ever seen a Protestant Church with no doctrinal statement. Ever.
Catholic doctrine is based on the Word of God.
Occasionally, that is very true. They get lots of things exactly right. It's all the non-Biblical additions that obscure the simplicity of the Gospel. Often Catholic doctrine is based on paganism, sadly.
The Church is the truth!
Christ is the Truth.
God does not change. The truth does not change.
We Agree! Stop the presses!!
