I would dispute that. Some of my RCIA students naively see the Bible, for instance, as if it were a manual of systematic moral philosophy. I keep pointing out to them that much of it is not exactly moral, and it's anything but systematic. It is full of weirdly mysterious things which you're stuck with (which I, a believer, am stuck with) whether they make sense to me at all, simply because they are true (defining true as: stuff that happened.)
Still less is Christ, Our Lord, an ideology. He is an infinite, divine Person who cannot be lopped off, shaped and framed into a human taxonomy system.
Ideology is antithetical to Mystery.
Think of it this way.
Humans are animals. They are not JUST animals, but they are indeed animals.
