A couple of luminaries writing in the Niagara Anglican reckon that churches are emptying because the diocese is determined to hold on to such outmoded esoterica as the Virgin Birth and the Resurrection of Christ.

This is odd, since all the priests who still believe these arcane curiosities left the diocese around 2008 – and the churches are still emptying.

From here (page 3):

Visitors to a church service from the secular world, hearing the creeds, listening to priests threatening Judgment Day, claiming that the Bible is the inerrant Word of God, asserting that Jesus was literally born of a virgin and literally raised from the dead, must shake their heads in astonishment. Those who cannot tolerate what they consider hopelessly out-of-date do not return.
