I hope that regardless of your religious affiliation and regardless of how or whether you celebrate something at this time of year, that you have a good time doing it. I'm just going to link you to two articles I read this week that I found profoundly interesting.
First, a blog piece from John Shore that is powerful, moving, and intense. Anyone considering going into full time ministry - especially the pastorate - needs to consider his words.
[Update: March 2013: I have updated this blog post to remove a link to an article by Hugo Schwyzer.]
