An Apology for the True Christian Divinity / Being an explanation and vindication of the principles and doctrines of the people called Quakers

The work presents a systematic defense and explanation of Quaker theology, arguing for the primacy of immediate, inward revelation alongside scripture. It advances propositions on human fallenness and universal redemption, the nature of justification, perfection, and the possibility of falling from grace, and practical matters such as ministry, worship, baptism, communion, and civil authority in religious matters. The text combines theological argument, scriptural interpretation, and responses to critics, and concludes with guidance on social conduct and conscience, aiming to vindicate the movement's beliefs and practices within a reasoned and ordered framework.
