I firmly believe that when Jesus himself wanted to explain to his disciples what his forthcoming death was all about, he didn’t give them a theory, he gave them a meal. Of course, the earliest exponent of that meal (Paul, in 1 Corinthians) insists that it matters quite a lot that you understand what you are about as you come to share in it; but still it is the meal, not the understanding, that is the primary vehicle of meaning.
