Encountered this word for the first and only time at an Anglican church, from a rector. I suspect that it is a word from Christian liturgy.
I had pointed out that two of the beliefs he had been promoting were completely contradictory - i.e. if one held one of them it was not possible to hold the other at the same time. He took this in stride, smiled easily, and used the word I am looking for.
In reply to the replies below:
Thanks all for the input.
"Antinomy", from philosophy, might be close, and "koan" might be another word for what the rector was describing!
Uh oh ... I'll admit that I am now wondering whether memory serves me well enough to recognize the word when I see it! Could antinomy be it? Koan is too short.
I'm guessing that the best bet for a definitive answer will come from a student of this level and form of Christianity. (Anyone care to call up their well-schooled rector? Orthodox Anglican as mentioned below.)
To answer questions posed to me here:
Unfortunately I do not recall the beliefs promoted.
It was in Canada and, when pressed, the rector - who did have a high-level affiliation with the Church of England - said that this flavour of Anglican would be "orthodox".
More as of April 13 2017:
I don't understand how this board works. Seems 5 users have claimed that my question is a duplicate. I am asked to explain why this is not the case. But I don't see where those 5 users have provided the "duplicate" question and answers ...
Also, there is a 2nd claim that this question has already been asked and answered - which includes a question which is clearly not the same as mine ...
Anyway, I've seen evidence neither of my question having been asked before nor its answer (though koan and antinomy are closest and on the right track). Thanks.
