It was while discussing with an older man who had come along to try to help me see the error of my ways that it became clear. It seems to be a generational thing to some extent, as it is always those of more mature years who exhort me not to think. Those of my own age think of that as something a bit theoretical, and are very happy to concede that thinking is in fact necessary. They are not blind to the problems of the brethren and their position, and realise that unless one is prepared to challenge elements that seem wrong, no progress will be made towards the ideal.
In fact, such brethren will admit to sharing a lot of my feelings about many things, while firmly differing on the conclusions.
But the older element see things differently from the base upwards. For them, my clarity of mind is an obstacle to overcome, a burden laid on me to make things difficult. I am told that thinking will always lead me astray, and to rely on faith instead.
And that's the point. If you start by assuming that logic will lead you to the conclusion that something doesn't make sense, which is the more sensible belief: that there is something mysterious (the religious word is "ineffable", I think) behind it that man is not intended to understand, or that it simply doesn't make sense?
At which point I am sorrowfully told that I have allowed the devil to get hold of my thoughts, while being assured that the statement is not meant personally.
I don't object to paradox and glorious ambiguity in christian doctrine - it's pretty much built-in, and I rather enjoy that. But I do think it's arrogant to apply the same reasoning to rules that people are expected to live their lives by. If you're instructing someone to do something at a cost, you should be able to back it up, not just fall back on "thou shalt not question, for this is the eleventh commandment".
