The Catholic Church simply renamed it "annulment". Besides, Who told you that all Protestant "churches" were correct? Protestant "churches", the Catholic Church, and individuals can all be in error. The Catholic Church is no better then some Protestant "church" when it comes to error. Employing and protecting homosexual priests is no better then some Protestant "churches" allowing homosexual pastors. Allowing those with resources to get an annulment is no better then some Protestant "church" allowing divorce.
For the record...not all who apply for one are granted an annulment. Means has nothing to do with it. And to make sure I understand your point...if we are all in error... Our eternal fate is at stake...we are left to our own devices and interpretations and hope we are right when we die...
I still would like to know where in scripture can we find the list of inspired scripture to be used in scripture
