just to catch up I go to a group every wednesday where a talk and meditation session is held, not in a temple or Wat as there are none in Aberdeen, but a FWBO group for a bit of company with like minded individuals (its the closest and easiest to get too)
I think the main difference between Buddhist "Sermons" and Christian sermons is that the Buddhist talks are questionable, it isn't a case of a bit of leeway here and there or move to another denomination or what ever, the talks are one persons point of view which we are encouraged to test and then agree with question or dismiss if we find it flawed.
I think if a Theravada version of the FWBO were to form it would be similar to modern/western Theravada except with an actual "Temple" monks, nuns, etc which is not associated directly with another countries tradition.
I think this will take time, and the first steps have started to happen, and I think the Thai forest tradition in the west will be at the fore of this, but for it to be truly balanced all the Theravada groups (Thai, Burmese, etc) should meet up (3 or 4 separate groups all looking for cultural add ons in the same areas) and go through the tipitaka, particularity the Vinaya and remove the area specific rituals, which are solely cultural add ons. but then again all the Vinaya lines should be involved there.

He who knows only his own side of the case knows little of that. His reasons may be good, and no one may have been able to refute them.
But if he is equally unable to refute the reasons on the opposite side, if he does not so much as know what they are, he has no ground for preferring either opinion …
He must be able to hear them from persons who actually believe them … he must know them in their most plausible and persuasive form.John Stuart Mill
