"Rays of Living Light on the One Way of Salvation" by Charles W. Penrose is a theological treatise written in the early 20th century. This work investigates the concept of divine truth amid the myriad conflicting religious beliefs and doctrines, emphasizing the necessity of revealed religion, divine authority, and the proper practices necessary for salvation. The author engages critically with contemporary Christian thought and presents a perspective aligned with the beliefs of the Church of Jesus Christ of Latter-day Saints. The opening portion of the text establishes a clear premise: there can only be one true religion since there is but one God. Penrose argues that the diversity of religious claims leads to confusion and asserts that religious truth must be revealed by God rather than invented by individuals. He critiques the modern notion that sincere belief suffices for salvation, emphasizing the importance of obedience to divine commands and the necessity of different sacraments, including baptism, as essential for attaining forgiveness of sins and receiving the Holy Spirit. Penrose's introduction sets the stage for a deeper exploration of these religious principles and the way to true salvation in the subsequent sections of the work.
