You hit the nail on the head there, Michael.
You said:
Your naïve view: Jesus established the one, true, Catholic Church ® and it has taught the True Gospel, unabated since day one.
We truly believe that which Jesus Christ taught. We truly believe that He is God. And we truly believe that He gave us His flesh and blood in the Eucharist. We truly believe that He speaks through His Church. etc. etc.
Protestants consider this naive. You guys claim to have faith alone in Christ alone. But you have only faith in that which you can understand.
Whereas, we accept, by faith, all which Christ teaches, whether we understand it or not. Whether we believe it or not. Faith is not always believing. Faith is also trusting in God.
