And this brings me to Lewis (and mine's) final point--Christianity is a complicated religion, and it is that very complexity which is evidence of its Truthfulness. Lewis says that it is the made up religions that are simple, because they do not adequately reflect the complexity of reality. Furthermore, since theology is an experimental science in which we are the interpreters of revelation, WE are the tools of the science (guided hopefully of course by the Holy Spirit), and thus, any religion will only be as close to God as the people who are charged to lead it. This, Lewis boldly states, is why "horrible nations have horrible religions". Because of this, as stated in the last post, the best instrument for interpreting the revelation of God is the Church itself, the community of guided believers who, though individually sinful and thus limited in their own abilities, as a group guided by the Holy Spirit holds the weight of infallibility and the power to fully interpret God's Truths. This is why as a Church, we must have the Magisterium, who is uniquely guided by the Holy Spirit and entrusted by Christ, as a group, to bind and loose the Truths revealed to us. This is why "spirituality" cannot be separated from the teaching Tradition of the Church, and any "religion" or "way to God" that claims otherwise is no true means of meeting Him.
"If Christianity was something we were making up, of course we could make it easier. But it is not. We cannot compete, in simplicity, with people who are inventing religions. How could we? We are dealing with Fact. Of course anyone can be simple if he has no facts to bother about."
