The Spirit of Christ is, to members of the Religious Society of Friends, synonymous with God. Quakers also use the terms Inner Light and "that of God in Everyone", among others. George Fox, considered the founder of Quakerism, and the other early Quaker preachers believed that direct experience with God was available to all people, without any mediation (e.g. through a pastor, or through sacraments).

Howard H. Brinton , a prolific Quaker writer, wrote how the spirit of Christ can bring people closer to God.

Man is saved, not by a leap of faith into the dark, but by giving way to the Divine Spirit . Since this Spirit is also the Spirit of Christ, man by obedience to it or by “putting on Christ,” to use Paul’s word’s, becomes Christ-like , able and willing to fulfill the teachings of the historic and the inward Christ.
