So “all” may not mean the “all” you mean? Hmmmmm.....
In Evangelical/Pentecostal/Charismatic churches, Romans 3:23 says, "For all have sinned, and come short of the glory of God." and means that ALL have sinned, and come short of the glory of God.
It seems that in the RC church (and it would seem apparently, a few Protestant denominations), that the scripture passage reads, "For all* have sinned, and come short of the glory of God." and means that all have sinned and fallen short of the glory of God, except:
* Mary, possibly Zechariah, possibly Elizabeth and whomever else our human leaders (Priest, Bishops and Popes) deem to be sinless.
IF your comment about the word "ALL" references Luke 1:5 “ …WALKING in ALL THE COMMANDMENTS and ORDINANCES of the Lord BLAMELESS”, then I direct your attention to Luke 18:18-23, Jesus’ discussion with the rich young ruler. Like Zechariah, he too, kept, “all the commandments and ordinances of the Lord” yet he could not enter the Kingdom of Heaven. It was NOT because he was rich, but that he valued his possessions ABOVE his love of God.
Unfortunately, it seems to me that the RCC is like the Pharisees, adding layer upon layer of man-made rules and sacraments, becoming a ‘religion’ and losing sight of the relationship that Our Creator and Saviour desperately wants with us! It has been this way for much of the last 1500 years with the RC church and I see this with a number of Protestant denominations as well. When ANY denomination becomes more about ‘tradition’ than relationship, they are off track. With this Pope, I see a humble man and I pray that he gets back to a style of church like was practiced in the Apostolic days.
