You can help people in a spiritual way without a degree. Helping spiritually is all about living spiritually. Being the example for others and inspiring them to be the best they can be.

Counseling, anything to do with personal interaction would be good if you want to help people spiritually. 

Also, I’d add helping children. I’m an intuitive, and spend a lot of time and energy helping children in foster care. I think a lot of us “psychic types” gain and receive a lot while serving kids.
