The Thomas Merton Foundation has announced the judge and complete guidelines for their 2007 "Poetry of the Sacred" contest. Coleman Barks is this year's judge, and you can get the guidelines here (pdf document). Deadline is Dec. 31, top prize is $500, and there is NO ENTRY FEE.
I will say that I am not altogether unbiased about this contest, as my poem "O" got one of the three honorable mention awards in the 2006 contest. It's a really good contest, though; they came through with the results right on schedule, called me on the phone to give me the news, posted the winner & honorable mentions on their website right away, sent my check very quickly, and sent me 4 contributor's copies of the print publication when it was available. It's a very professionally-run contest. And their definition of "poetry of the sacred" is very broad -- definitely not just poems about religion or God or anything like that. (I mean, my poem was about "ooh, lookit the whale, how cool!") You can read all the past winners and honorable mentions on their website. There's some excellent stuff there.
So send them a poem if you've got something that seems to fit! Good luck to one and all. :)
