“Benedict is still wearing the papl vestments - no other “resigned” pope in Church history has done that.”
There has not been a resignation (until Benedict) in many, many centuries and there was no “papal vestments” at that time. Seriously, the papal whites are a “recent” innovation of the 16th century.
“Benedict is holding the papal title of “pope emeritus” - again, no provision in Catholic doctrine for such position, nor has such practice ever occurred heretofore in Church history.”
It’s not doctrinal. It’s practical. It’s a title, not an office. It was so people would know how to address him and to ensure he would - by his own written laws - be able to stay at the Vatican so that he would never be used as a weapon against any successor.
Don’t feel bad. Even Vatican archbishops aren’t getting this right: http://catholicherald.co.uk/news/2017/05/04/vatican-archbishop-i-do-not-agree-with-the-title-pope-emeritus/
The fact remains that a pope cannot claim to dispose himself of the governing aspect of the Church, but claim to hold the contemplative aspect. This is an intrinsically flawed position that violates Cannon 188.
Benedict, in his own words of “resignation” stated his purpose of doing that which is illicit: bifurcating the papacy. His resignation is therefore fundamentally flawed and invalid.
