The Pope, speaking ex-cathedra and the decisions of the Magisterium are binding and said to be infallible

Papal Infallibility has only been used once- and not of this issue

1) I see from a quick search that the attribution for the quote you provided--which you called a "good explanation" of the doctrine of justification--which I requested but you did not provide, turns out to be from Wikipedia's article on "Justification (theology)", subheading "Catholic views". In the future it would be both helpful and appropriate to document such attributions.

Wikipedia is a tool I use often- I check the citations given and go back to the cited sources and find my reasearch there. It's a great tool to find such websites.

Which means that your answer to my question is in fact "yes"--there is a particular circumstance which would cause God to regard a person as justified and then later as unjustified, which invalidates your own unqualifed statement "Justification is a one-time thing- one in which cannot be taken away from a person"..

No- I am merely pointing out that this is my personal belief- and not the belief of many Catholics since Pilgrim especially pointed out that my beliefs don't always fall into line with the majority of the Church.

Which means that your answer to my question is in fact "Maybe Yes and Maybe No"--there may or may not be a particular circumstance which would cause God to regard a person as justified and then later as unjustified, which cannot be logically reconciled with your own unqualifed statement "Justification is a one-time thing- one in which cannot be taken away from a person".

My point here is that the Church is still in conflict about the smaller points of this issue- the Church has been going through reform and certain issues are "still under renivations" if you will.

One of the differences I see is in the way the two groups view justification applied to believers. Rome uses the word "infused" to describe Christ's righteousness applied to believers, while the Scripture (and protestantism) uses the word "imputed" to describe it. Huge difference here!

Just curious- what biblical references do you use, I could never get them from my old baptist minister.

Gloria Patri et Filii et Spiritu Sancti, Amen!
