Christianity is not a doctrine, I mean, a theory about what has happened and will happen to the human soul, but a description of something that actually takes place in human life. For 'consciousness of sin' is a real event and so are despair and salvation through faith. Those who speak of such things (Bunyan for instance) are simply describing what has happened to them, whatever gloss anyone may want to put on it.

Everything ritualistic must be strictly avoided, because it immediately turns rotten. Of course a kiss is a ritual too, and it isn't rotten, but ritual is permissible only to the extent that it is as genuine as a kiss.

— Ludwig Wittgenstein

Everything that can be thought at all can be thought clearly. Everything that can be said can be said clearly.
