That is a desired but unwarranted conclusion. Invoking the fact that someone used something or even spoke truth does not mean recognizing that person has authority and defines doctrine, nor does it necessarily mean they concurred with all Rome teaches now, much less with its contrast with the NT church .
Rome herself will quote so-called church "fathers," but as there is disagreement btwn some material from such and what Rome teaches, thus she judges them more than they judge her, and the only real authority is Rome, is she does say so herself.
Just so you know, I do not respond to posts whose only content is an attack on the RCC. She has worthy defenders here. I also will not engage in the difference that the Orthodox have with her. This forum is not the place for that. If I seem to be “defending” the RCC, it is because there is much common belief that I can do so, based on a thousand years of common history.
