So you think all that is in Papal Encyclical (and perhaps Bulls) is infallible, and or you suppose such are “commentaries on the whole Bible,” which is what i was referring to?
Not all that is in there is infallible, but unlike the works of Matthew Henry, Keil & Delitzsch, Jamieson, Fausset and Brown, Barnes, Clarke, etc. there can be found infallible teachings within them.
Peace be with you.
