Naw, he was always kinda the kooky star traveler. On his trip to the moon he experimented with mental telepathy trying to communicate from the Apollo capsule to earth using playing cards, etc. IIRC he was a half bubble off about religion until later in life.
I lived in his home town at the time of his mission and he gave the most amazing color slide presentation to the citizens and school children. The pictures, projected onto a movie theatre type screen were absolutely stunning in their clarity and crispness. I think they were all taken with the Haselblad(sp?) large negative cameras and the detail was unbelievable at the time.
If he believes that aliens from outer space has brought peace to the earth, he is still a little more than half bubble off about religion.
