The article contains an example. For hundreds of years, the Catholic Church taught that anyone who wasn’t under the authority of the Pope was damned (”it is absolutely necessary for the salvation of every human creature to be subject to the Roman Pontiff.”). Now it claims that darn near all Christians might be saved.
And how is this done? By claiming that all Christians ARE subject to the Pope, even those who utterly REJECT the office and authority of the Pope.
So ‘no error’, just breath-taking intellectual dishonesty.
