I can point you to a Catholic publication, and by that I mean published by⌠I think Notre Dame Theology School, by an advisor to the Pope on Vatican II, that takes for granted that the Church changes its moral position over time. My claims are not âoff the wall,â but the considered opinion of some pretty serious and well informed Catholic theologians.
This is pretty vague. If the âtheologiansâ were relating shifts in emphasis, shifts in theological language, shifts in
explanation of doctrine, in sacramental understanding, shifts in priorities, shifts in practices, shifts in discipline, and expansion of how the Church describes herself, including an understanding of how she functions, then those are potentially correct contexts for the concept of âchange.â
However, not a single element of that has anything to do with core doctrine. So, if those theologians are stating that
core doctrine has âchangedâ (not the wording of it or the understanding of it or the explanation of it or teaching of it, but the facts of the doctrine itself), then those theologians, whatever their titles, are in error. How do I know this? How can I state that factually, not as âmy opinion?â Because anyone truly educated in the faith knows that doctrine proceeds not from theologians or local parish priests, let alone from what is popular among the laity, but only from the Magisterium in Rome. Only. Nothing else is a source of authentic doctrine (which is a doctrine which also derives from Sacred Scripture and Sacred Tradition, by the way â i.e., what was always held to be true and fundamental in the Church).
So, if youâre going to state with any credibility whatsoever that University of Notre Dame theologians claim that Church doctrine has changed, you will need to share with us which specific doctrines they are speaking of. I canât think of one right now. No settled dogma. No settled doctrine. There are wish-fulfillments, both by some theologians and many lay people, and also by various CAF posters

, that âthe Church would change,â but so far that has not happened
when it comes to doctrine.
Your âtakeâ is either a result of a misunderstanding, or the persons to whom you refer are
in error.
