Neither do your quotes from the ECFs indicate any such thing.
You may have missed the phrase "in any sense at all". Obviously Catholic doctrine does change in the sense of "development of doctrine." This refers to a doctrine being reaffirmed and clarified in the light of new situations, being re-stated to answer new questions, being widened or refined in its application, being deepened, extended, elaborated, made more precise, etc. etc.
All that can change, and does. It is not contradiction, it is development.
What does not happen in Catholic doctrine, is abrogation. Something that was true 20 centuries ago, was true 200 years ago, was true 20 years ago, and will be true two or three or a thousand pontificates from now, per omnia saecula saeculorum, until Christ comes again.
And even if any FReeper Catholic could be found who erred on either side --- who said either that "nothing changes in any sense" or that "the basic doctrines do change," --- that FReeper Catholic would be factually in the wrong, and his/her remarks would need to be corrected by some rmemedial catechist.
Which --- God help us all! --- seems to be my vocation!
Mrs D, I know you're a committed Roman Catholic. But being so, you cannot see the forest for the trees in this case.
We'll continue with the argument about the celibacy of the priesthood.
There was no requirement of celibacy in the early NT church. There was no requirement of abstaining from sex as a "priest". Those doctrines came about in the 300s and continued to undergo revisions over time...some pretty evil in nature and contrary to the very institution of marriage initiated by God.
Celibacy was not required by any NT writer.
This is where your argument falls apart.
It was not true 20 centuries ago. It's only been that way in Roman Catholicism since the early 300s.
My arguments are falling apart? Nonsense. What I asked was for you to locate for me some FR Catholic who asserts that "the Catholic Church's practices and beliefs have not changed (in any sense at all) over time". The link you provided did not lead to any Catholic saying any such thing.
You did see the title of the thread...right?
The Church's Constant Teaching on our dealings with Non-Catholics
Now, if you're trying to argue a poster didn't make a comment saying that then we've entered the Clinton world of parsing words...."it depends on what is means" or such nonsense.

Yes...the Muslims have something along those lines...it's called abrogation.
It is WAY too soon to TRY to move your goalposts; Dear.
