What is Walter Cronkite's religion?

According to wikipedia... Cronkite's family was Protestant and changed their denomination three times while he was a child. Cronkite himself joined the Episcopal church as a youth explaining in a 1994 interview: "I got into a Boy Scout troop that met in an Episcopal church. The church had a wonderful minister who was also the scoutmaster. And I suppose you can say he proselytized me. At any rate, I was much involved with the church, and became Episcopalian - and an acolyte. Later, when I worked for a paper in Houston, I was church editor for a while. The Episcopal House of Bishops met in Houston one year, and I became intrigued by the leaders of the church - fascinated by their discussions and their erudition."
