What is the Catholic Church's "raison d'etre" in the 21st Century?
Isn't our raison d'etre to convince EOs, OOs, Anglicans, Lutherans, Methodists, etc. to become Catholic?
Ohhhhhh ... Sorry, never mind.
How about if we took the approach that we are all diminished by our divisions and that there just might be something we can all learn from one another.
The Roman Catholic Church has all kinds of internal problems that Catholics don't seem to want to seriously deal with because that effort might undermine the view that "we are the true church."
Today, if I had the choice to be either a Latin Catholic or an Eastern Orthodox/Oriental Orthodox, I would definitely become EO/OO.
For one thing, the East, not in union with Rome (if I were EO, I'd say that Rome was out of communion with the true Church re: heresy) has a tremendous sense of mystery and knows how to honour/adore the Great and Terrible God, the Lord of Hosts.
The Latin Church is sadly lacking in that in many places.
And the recent popes were/are aware of that.
