Question: Has the Catholic Church ever made a proclamation ex cathedra (as in, one which it declares is infallible) that it later retracted?
This could literally be any form of the following:
- Some statement X was made, intended to be infallible
- Later, X was retracted/reformulated/revised by a subsequent "infallible" statement, illustrating that the previous statement was obviously not infallible
Background: I was recently shown the site Catholics Come Home and was perusing their top ten reasons to "come home," which featured this:
This [Catholic] Church has been guided by the Holy Spirit and protected from teaching error on issues of faith and morals from generation to generation for some two thousand years, as Our Lord Jesus promised: (foretold Isaiah 22:15-25) Matt 16:13-20; Matthew 18:15-18 (in this verse the word is church, not community); 1 Tim 3:15.
While the phrase above seems bold, I have the feeling its meaning applies only to statements made ex cathedra (from the chair), i.e. those statements made explicitly as infallible by the Pope. For background, the Church's stance on papal infallibility only applies to faith and morals (hence I'm thinking the above quote is only referring to those instances):
To fulfill this service, Christ endowed the Church's shepherds with the charism of infallibility in matters of faith and morals. (Catechism of the Catholic Church, #891)
For a short list of times this actually happened see Wikipedia’s list of infallible declarations.
I found some people asking this question on Catholic Answers Forum, most notably this list (link dead), extracted from a recommended book on the matter, Fundamentals of Catholic Dogma.
