“The same fall and winter a large school convened for instruction, composed of Elders, and members of the Church. Elders Smith, Rigdon, and others, acted as teachers.” — Jedediah Grant1
The Lectures on Faith were given at the School of the Prophets in Kirtland, Ohio, during the winter of 1834-1835.2 It's not clear who authored the lectures, but later reminiscences point to Joseph Smith, Sidney Rigdon, and possibly others.3
Designed to deepen understanding of God's nature and the principles of faith, the Lectures on Faith could represent an early theological foundation for the Church's members. They cover topics such as the nature and attributes of God, the necessity of faith for salvation, and the principles of obedience and sacrifice.2
The lectures were included in the 1835 edition of the Doctrine and Covenants but were later removed from the Doctrine and Covenants in 1921.2
