If you were in charge of a starship (earth to another galaxy) would you allow religion / believers onboard?

"Listen padre. I'm the Captain of this boat. I understand my peoples' need for you. I reckon you do too. But it's not about what I believe or what you believe - it's not about you or me. It's about my people on my boat, and what they believe and need. So I am going to let you stay on board and do your job - as long as you realize that's what you're doing."
