Being a PK myself (as well as 3 sons) it is always interesting to ferret out another: they tend to be either advanced scalawags or else geniuses of a more positive stripe.
For starters I might begin where I started college, a Methodist college; there were two there that I knew. (This was in 1943, when everyone 18 or older was snapped into the army, but quick.) The scalawag managed to avoid military service by going to sea as a merchant seaman. The genius declared for seminary training, was deferred through the war, and next thing I knew was a D.S. (Methodist District Superintendent), following in the footsteps of his sainted father.
Things rocked along until at 31 I found myself in seminary, where I did a lot of reading, trying to catch up with the gifted boys who had dedicated their lives to religion from an early age.
One of the books was called "Source of Human Good" by a man named
Henry Weiman. Weiman, the son of a Presbyterian minister, and a Presbyterian minister himself took what was for the early 20th century a strange religious path. He set out in search for what he called the source, (what we perhaps mean by God), but he threw out all belief and depended strictly on naturalistic thought forms.
I have gone into such length about the third PK because friend Henry had a marked influence on my theological orientation. Looking back from a long perspective I can see how it resembles my "search for spiritual authority" and my distrust of ecclesiastical (ostensibly spiritual) authority. In fact he used the same word that I settled on in my skeptical approach-orthodoxy.
I rejoiced to rediscover him after these many years and realized where my distrust of eccleiastical institutions had to some degree its beginning. Quakerism is a refuge for such an attitude; Henry chose a similar one, Unitarianism.
IMO Quakerism and Unitarianism have a great deal in common; the chief distinction may be that some UU's have a stronger theological interest than some Friends.
Blessings to both groups -- and to all groups; the mother group is the human race.
