I take it you're not Catholic then?
Catholics have got to learn to be less defensive. Its almost like any critique of the faith is an "attack." I'm just offering my opinion, nothing more, nothing less.
The fact of the matter is that I have read scripture, as well as the work of Augustine. All of these indicate that Christ will only appear during the second coming. Christ himself explicitly said this.
Most of these apparitions are pious fiction. They serve a purpose in terms of illustrating a moral, but I don't take them at face value (neither do most Christians, including many Catholics).
