I have noticed that there seem to be a lot more patristics enthusiasts here than on most other protestant forums . . . so here is my question . . .
There is a very famous letter from Gregory the great to John of constantinople, saying some things that any non-catholic would instantly take as explicit denial of the papacy. RC apologists argue that the context does not indicate that, and also that he also promoted the papacy and excercised his papal powers on several occasions.http://www.philvaz.com/apologetics/num7.htm
(Look half way down to see the bit I am referring to.)
What would you say? Does this argument deserve to be relegated to the "do not use" list?
