The Christian, of which I am, relies on the Word of God. There is nothing else to point us to Heaven and how to be saved.
No. The protestant relies upon their own understanding which is not a measure of faith. The signature phrase used is, "This speaks to me." Whether used in an intellectual or emotional context is up to the individual protestant. Either way it's not about Faith in Christ but about what is deemed acceptable according to personal predilections of the protestant.
As soon as the protestant comes across something that does not conform to their preconceived notions it is jettisoned. Relativism is the order of the day within the protestant ecclesial community. Which is why it will not survive for much longer. People need more than what they have to offer. Because they are not simply offering Jesus. But Jesus as they perceive Him and because of the man-made filters they've erected around Christ, people don't see Him.
