The apostle Paul was one of the few who actively sought after "the fellowship of his sufferings", not as a means of attaining a false righteousness, but so he could also experience the "power" of the ressurrection of the Lord. I want that too, as well as all the fellowship with him that I can get.
I'm not a Catholic, but I admire the tradition within the Catholic Church that is willing to look deeply into this particular aspect of our walk with and imitation of Christ.
** As the song goes, “Everybody wants to go to heaven, but nobody wants to die.”**
At least, die to self and self-pride. Gets me all the time.
