The experience of being gathered by God leads into the experience of being guided by God. This was not just the experience of individuals, important though this is. The key to the development of Quakerism is the understanding of corporate guidance which tests and informs individual leadings. At the heart of this is the meeting for worship where Christ, the Inward Light, is present and is met. Fox often wrote that Christ has come to teach his people himself. From this teaching comes Quaker faith & practice.
Mary Fisher (1623?-1698), after travelling to preach to the Great Turk, testified to this universal Light:
Now returned into England ... have I borne my testimony for the Lord before the king unto whom I was sent, and he was very noble unto me and so were all that were about him ... they do dread the name of God, many of them... There is a royal seed amongst them which in time God will raise. They are more near Truth than many nations; there is a love begot in me towards them which is endless, but this is my hope concerning them, that he who hath raised me to love them more than many others will also raise his seed in them unto which my love is. Nevertheless, though they be called Turks, the seed of them is near unto God, and their kindness hath in some measure been shown towards his servants.
