I would go so far as to say that faith is integral to even making sense of the whole thing. You know, when all the pieces come together and there begins to show a consistency.
Orthodoxy is a Church of parables. Think of it this way, even in the Gospel accounts, Jesus Christ did not simply tell parables, His entire life was a parable!
And so it is with the church. Every thing that The Church does is a parable of something. And I heard it said by an old retired presbyter that the Sacred Mysteries are mysteries in the sense that they are to be experienced, not solved.
And even our life is a real mystery, to be lived out.
We are each made in the image of God. That being the case, to be truly human is to keep that image pure. Sin is like dirt and smudges on that image. We are living Icons.
And well, The Church is a hospital. It is there to help you not just to keep that image pure, but to help you to know how! And really, it is God who cleans you, but you do play a part in it. That part is cooperation. God does not force people to accept him, it is a free will choice.
So if it all looks strange from the outside looking in, realize that even when these things were first instituted as practices it was just as strange. It is the way it is very much with purpose, and it isn't simply a situation of "Oh people in ancient times sure were strange. Look at how they did things as preserved in these people who can't get with the times!".
