Had there been any significant pent-up demand for either of these initiatives, many more existing communities would have joined in the first wave. In the event, only about thirty did so, many of them only a small fraction of the original congregation. The last group of this sort was St Michael's, Denison, whose dozen members entered in March, 2015. It is not impossible that other parishes, including OLA and St Mary's, may eventually join, but on the other hand some of the smaller groups have already disappeared.I'm beginning to formulate a more settled opinion that Anglicanism in whatever flavor is a syncretism that may tantalizingly lean more or less Catholic, but it will always be at best a syncretism. A recent notion I've come to see in John Guy's Elizabeth: The Forgotten Years is that James VI of Scotland was able to secure a reluctant consent between Henry IV of France and Pope Clement VIII -- Catholic anti-Spanish forces -- that he should succeed Elizabeth because his wife, Anne of Denmark, had already converted, and perhaps James would, too.As you have frequently noted, the market among existing parishes was greatly over-estimated by those who originally pitched the idea. So the way forward would seem to be "gathered" groups of which there are eight or so now. This is a much more challenging model, and in the five years since its creation the OCSP has seen no parish grow in the same way that OLA did in a similar space of time. Leaders of Fr Phillips' sort will always be exceptional.
Meanwhile the Ordinariate struggles to erect the structures that will enable it to function effectively as the equivalent of a diocese and ensure a supply of clergy for its existing congregations. The fact that a leader had to be found from outside the Anglican tradition tells us a lot about the weakness of the concept.
In other words, a Catholic style in Anglican religion can be useful, but is always subordinate to political gamesmanship and personal agenda. Playing footsie with Anglo-Catholics is always going to be a risky proposition.
