One might wonder about confusion from a church that proposes that its doctrine does not change.
Yes, one might wonder. :) Every time a new ruling is handed down it is what they have always and everywhere believed. Why don't they just write down and pronounce all of their beliefs at once and be done with it? I suppose that would unfairly take away power from future Popes to, uh, ....... say what they have always believed? Hmmmm......
