Is any portion of educational travel eligible for deduction?

I'm a pastor, and will be going on a trip to Greece and Turkey. The trip focuses on historical sites and events.  This will improve my preaching and teaching, and I will be leading classes afterward on about the trip and all the related places.  I am not, obviously, meeting with clients, making sales, etc.  Purely educational.
Given that, is any portion of this trip deductible, and which/how? 

Thank you.
