As Quakers expressed and reflected upon their experience of life under the guidance of the spirit of Christ, they developed a rich vocabulary to describe those experiences. This vocabulary played an important role in Quaker spiritual formation and community life from the beginning of the movement in 1650, and continues today as modern seekers wrestle with describing their experiences. When Bill Taber died in 2005, he left behind notes on a project: "A language for the inward landscape." Key phrases provide important insights into the nature of inward experience over time and can help people explore their spiritual experience with an enriched vocabulary. Brian Drayton compiled these notes and expanded them. Readers (both Quaker and non-Quaker) may find this language conveys a distinctive "alternative Christianity" combining mystical and prophetic experiences with God and in community.
