::It is my understanding of the history that  point is currect.  Quakerism grow out of the religions that were already present, less related to the Church of England at the time, and more reacting to the growing Puritan movement.  In part a rejection of them, but not entirely.  Many of Foxes eariest converts were members of Cromwell's New Model Army, and were (until their expusion) considered to be in good standing both with the army and with God.  To give extact references I'd have to take some time to dig it out.
