I did _not_ say that Ireland wasn't very Celtic. Ireland was Celtic by
definition. But the idea of a "Celtic Church" implies that the churches of
the Celtic nations had some kind of centralized or unified ecclesiastical
organization, which they did not. See the essays by K. Hughes and W.
Davies I referred to in my earlier message.
I _did_ quote a statement by F. J. Byrne to the effect that the Irish and
Welsh had no sense of a common ethnic identity. That doesn't mean that
they did not share a Celtic cultural heritage. But if they were not
specifically conscious of their historical and linguistic relationship, and
did not have a unified ecclesiastical hierarchy, then the concept of a
"Celtic Church" (singular) is misleading at best.
