The Venerable John Paul 2- Yes!
Today the Vatican announced that John Paul 2 has been declared "venerable." What that means is that after extensive study since his death, the leadership of the Church has declared that Pope John Paul 2 has lived a life of heroic virtue, which is the first step to being declared a saint.
How can mere men make these outrageous claims?
Is it arrogant for mere humans to declare someone a saint*?
The answer to these questions is found in Holy Scripture (Matt 16:19; 18:18). Jesus told his apostles, his successors, that what they bind on earth will be bound in heaven. The process of beatification and canonization is just one practical example of this promise being carried out here and now, 2000 years later by the successors of Peter.
*(meaning the Church makes a binding statement that an individual is in heaven and a model of heroic virtue for the faithful to emulate and request intercession)
