According to Freemasonry, divine light is only obtained through Freemasonry because it is divine in origin and true religion. Here is a quote from Masonic literature:
"Masonry is of divine origin" (J. Blanchard, Scottish Rite Masonry Illustrated [The Complete Ritual of the Ancient and Accepted Scottish Rite], 1:453).
Here is another quote,
[E]very Masonic Lodge is a temple of religion, and its teachings are instructions in religion....reward is the knowledge of the True God....Masonry is a worship....It is the universal, eternal immutable religion, such as God planted it in the heart of universal humanity" (Liturgy of the Ancient and Accepted Scottish Rite of Freemasonry for the Southern Jurisdiction of the United States, Part Two, pp. 167, 1980-99).
The Bible teaches that our Lord and Savior Jesus Christ is the true Light of the World. Masonry denies the true light that gives light to every man and until they process Jesus Christ as the only true Light they will always be a lost and counterfeit religion.
