For now, I'll leave you with G.K. Chesterton, who could say infinitely better what I want to say, and, in fact, basically does so, without my minor additions.
What is any man who has been in the real outer world, for instance, to make of the everlasting cry that Catholic traditions are condemned by the Bible? It indicates a jumble of topsy-turvy tests and tail-foremost [I died with mirth the first time I read this phrase, the Victorian/post-Victorian way of saying "ass-backwards"! -- EBB] arguments, of which I never could at any time see the sense. The ordinary sensible sceptic or pagan is standing in the street (in the supreme character of the man in the street) and he sees a procession go by of the priests of some strange cult, carrying their object of worship under a canopy, some of them wearing high head-dresses and carrying symbolical staffs, others carrying scrolls and sacred records, others carrying sacred images and lighted candles before them, others sacred relics in caskets or cases, and so on.
I can understand the spectator saying, "This is all hocus-pocus"; I can even understand him, in moments of irritation, breaking up the procession, throwing down the images, tearing up the scrolls, dancing on the priests and anything else that might express that general view. I can understand his saying, "Your croziers are bosh, your candles are bosh, your statues and scrolls and relics and all the rest of it are bosh." But in what conceivable frame of mind does he rush in to select one particular scroll of the scriptures of this one particular group (a scroll which had always belonged to them and been a part of their hocus-pocus, if it was hocus-pocus); why in the world should the man in the street say that one particular scroll was not bosh, but was the one and only truth by which all the other things were to be condemned? Why should it not be as superstitious to worship the scrolls as the statues, of that one particular procession? Why should it not be as reasonable to preserve the statues as the scrolls, by the tenets of that particular creed? To say to the priests, "Your statues and scrolls are condemned by our common sense," is sensible. To say, "Your statues are condemned by your scrolls, and we are going to worship one part of your procession and wreck the rest," is not sensible from any standpoint, least of all that of the man in the street.
