Recently Bishop Patrick Dunn has made presentations around the Auckland
diocese telling of some of the challenges he perceives our Church to be
facing. One theme he developed was to do with the numbers of people in
our congregations. He explained that if one looks at census returns then
it seems that Catholic numbers are holding up rather than declining as
is happening for some other denominations. However, it appears that we
in the Auckland diocese are being misled simply because the number of
Catholic immigrants gives the impression that our churches are just
as full as they have ever been.
