I recently had an online debate with some fine folks who are atheists, but consider themselves as mystics.
First, let’s define some terms:
Mysteries: “Mysteries of God are spiritual truths known only by revelation. God reveals his mysteries to those who are obedient to the gospel. Some of God’s mysteries are yet to be revealed.” [LDS STUDY GUIDE] & [also see NIBLEY]
Atheist: “…is the position that either affirms the non-existence of gods or rejects theism.” [Wiki]
As Christians we need to have genuine love and respect for all people. Atheists are just people who haven’t crossed over the river yet. They can be good neighbors and friends. So no one is preaching hate here.
That being said, as stated in the definition above, mysteries have to do with “revelation” and “God reveal…[ing] [H]is mysteries” to man.
Mysticism is ascension. The Zohar has the Tree of Life as its backdrop (a symbol of the temple). The same for the Book of Nephi (if not the entire Book of Mormon), The same for the Bible (it begins and ends with the Tree of Life). And of course The Pearl of Great Price.
Nephi saw only one path to the Tree of Life, not one for believers and anther for non-believers.
Jacob saw one ladder. Elijah one chariot. Ezekiel saw one river. Moses went up one mountain. Solomon’s Temple had one center path.
There is one ascension pattern for all people. There is no ascension without Christ. There is no secular, evil, or atheistic ascension.
We ascend by keeping the principles and ordinances of the gospel. We learn truth upon truth until we know all things.[D&C 94:27-28]
