Sorry, I could only think of Matt Foley - which probably isn't helpful (pardon advertisement). Definitely sweaty, definitely passionate, unfortunately not a real person... posted by Nanukthedog at 4:16 AM on March 3
You might like Eckhart Tolle; his passion is a little more subdued and meditative. He does discus 'God' but it's a loose definition of a sort of greater energy and spiritually inclusive. His speaking style may take some getting used to. posted by dog food sugar at 7:34 AM on March 3
You might check out Nikki Giovanni. Nikki Giovanni is a secular poet. The link I provided is a link to a segment she did on the Bill Moyers Journal, but I think it's relatively non-religious.
Nikki Giovanni is passionate, heart-warming, and life-affirming when she speaks. I've watched her interview video on the website a couple of times. posted by SocialArgonaut at 8:53 AM on March 3
