The main post and Moynihan Rpt #7 are both worth reading.
The latter distinguishes between ‘retire’ vs ‘renounce.’ Now to consult the dictionary for where/if ‘abdicate’ fits in.
Abdication:1:a formal resignation and renunciation of powers; thus I intrepretate Pope Benedict’s move as the same as King Edward VII’s. He will return to being Cardinal Ratzinger, and thus no ‘two pope’ problem.
"dichiaro di rinunciare al ministero di Vescovo di Roma" (DECLARATIO)
This dictionary says, as a transitive verb it expresses "abdicate":
There have been several sources that have attempted to clarify the terminology vis a vis the mainstream media. When I post these threads, I do so in their original format.
Thanks for the ping. Abdicate is the proper word for this action.
