Anglican Hot Cross Buns?

I was looking through a new cook book that appeared in our kitchen this week when I came across a recipe for hot cross buns. Above the recipe was written "It is said that these buns were first created by a 12th-century Anglican monk, who placed the sign of the cross on the buns in honor of Good Friday." Now, I'm a little confused. Wouldn't an Anglican monk before the Reformation have been in fact a Catholic monk?
