The ordinary form stresses such elements as the participation of the faithful, the use of the vernacular, the ongoing development of the liturgy by the addition of new saints to the calendar, etc.: these are all very important. At the risk of oversimplifying, I would say that the ordinary form stresses rational understanding, speaking in prose, as it were. The extraordinary form provides rich food for the intellect also, but relies heavily on gesture, symbolism, intuition, silence, ritual action without words, speaking in poetry, you might say. Man knows both rationally and intuitively. He needs both prose and poetry. If the two usages, like two different cultures, can patiently live with each other over time, they can become friends.
More poetry please!
It will be interesting to see how the two forms will live side by side in the monastery. For more on the story of this foundation, here is the monastery`s website.
