One thing that has fascinated me about these letters was watching the change in my father's religious beliefs. His grandfather Albert Ozborn was a Quaker minister in a Friend's Church in Iowa. Dad attended the Friends church as a child and also went to tent revival type gatherings, he also considered becoming a minister himself. In this letter he mentions evangelism and the difference between his beliefs and others in the camp. His beliefs change in the next few years.
After the war he and our mother Dorothy help to found the Mountain View Friends Meeting in Denver, Colorado. This is an unprogrammed (spell checker does not recognize that word) Meeting as is Las Cruces Friends Meeting which I belong to. The Friends Churches have ministers or a planned program, while those of us who are un-programmed worship in silence, which is broken by ministry from any of those worshiping.
