I love this little section of today's first Mass reading 2 Corinthians 6:12ff:
We are treated as deceivers and yet are truthful;
as unrecognized and yet acknowledged;
as dying and behold we live;
as chastised and yet not put to death;
as sorrowful yet always rejoicing;
as poor yet enriching many;
as having nothing and yet possessing all things.
I cannot think of a better epitaph. To be misunderstood by the world by living for Christ. Better still, I guess, would be to have the humility to desire that this NOT be my public epitaph, to be recognized and/or admired for living through this friction with the world, but to die without regard, to hear "Well done, my good and faithful servant" only in God's voice.
