Uh, if you had bothered to actually READ the FULL definition of an infallible teaching, you would see that it has to meet FOUR critera, not just the one you pointed out. Simply sticking in the word "anathema" doesn't fulfill the requirements. I say again--the specific language used in the Mass is neither a matter of faith nor a matter of morals--it's a "company policy decision", for which there were probably valid reasons at the time it was promulgated, but which the later (and equally empowred) Council and Pope have obviously decided are no longer extant.
I did and it did. If fact, the section I pointed out to you explained that most infallible pronouncements are easily identified as such, and if any "doubt" could possibly remain an anathema attached puts an end to all such doubt.
Here is some more from the same source:
"All the councils, from the Council of Nicæa to that of the Vatican, have worded their dogmatic canons: 'If any one says . . . let him be anathema'."
