Obviously, the theological censure of heresy is irreformable. But what about the lesser theological censures (eg., “injurious to pius ears,” etc)?
And if these lesser censures are reformable, what are the implications for disciplinary infallibility (which could not simultaneously be both infallible yet reformable)?
This article discusses the infallibility of lesser theological censures, within the context of arguing for the infallibility of Quanta Cura, but apparently without acknowledging the disciplinary infallibility of the Church.
Very enjoyable reading (and a couple interesting follow-up/related articles references at the end:
