Catholic dogma HAS been changed twice in the last 200 years.
Do you mean that the Dogma of the Immaculate Conception was clarified (1854), and the the Assumption of the Blessed Virgin Mary (1950)?
Well... come on, now! :) I *was* talking about things other than dogma going from “non-definition” to “definition”!
I’m not sure that I could say that I “changed” from going from non-existence to existence, since there was no “me” to change, before the point. As for dogma, the idea of the Immaculate Conception was certainly there, but not “dogma” yet, you’re right. Semantics, I guess; are we really in disagreement, here?
