OK, you might be surprised, though, in looking closer, that the CC and others aren't as far away from your position as you think, even within the variations of interpretation. Sacraments, for example, are thoroughly spiritual even as their form is physical. (The Eucharist is the recognition that we must partake of God, and partake of Him worthily, BTW-the theology is built into these simple physical acts which have served the faith of often simple and illiterate peoples for centuries and continues to now). But that's for another thread I suppose. Theology isn't bad. We all do it; we're doing it in this thread. It means to define the nature and will of God. The Church has a huge, rich wealth of this thought, pondering God's revelation, as well as direct grace-filled experiences in some case (another topic) for 2 millennia, and continues to, in both Protestant and Catholic camps, with great strides in better understanding of the faith resulting.
The whole enterprise of the Church, with its apparent megalithic structure, worldwide presence, sometimes wild and varied history, human foibles, et al is aimed at one thing: the establishment of relationship/communion of the individual with God. It's performed that task sometime better, sometimes worse, but that's the purpose. And I know Him better than I otherwise would as a result of all the witnesses that came and all the work that was done before me.
