I know it really doesn't make much difference, but in studying secret societies and other occult groups, most are a modern day continuation of Gnosticism and of the ancient mystery religions.
The designs & symbols of these occult groups are essentially the same, whether - kabalists, Gnostics , Knights Templars , Rosicrucians, Illuminati, or Freemasons.
In the 1800s, there was a move by Rosicrucians and Freemasonry to form and grow Masonically inspired Religious Cults for the purpose of undermining and sabotaging Christianity , as well as influencing them toward globalization and the acceptance of the New World Order .
Besides forming the New Age Theosophical Society , Freemasons & Rosicrucians participated in the rise and spread of Christian Science, Unitarianism. The Adventists , the Mormon Church of Jesus Christ of Later day Saints , Jehovah's Witnesses and other offshoot Religions of the nineteenth century.
In studying symbols of these occult groups, the prominent symbols that Charles T.Russell used were those of the Rosicrucians.
The Rosicrucians were also called the invisibles because they kept no lodge records of members, nor did they wear aprons or any other distinctive clothing , and were only known to other members.
But the beliefs were identical because of the connection to the ancient mystery Religions.
The main symbols of the Rosicrucians are two - the Egyptian Wnged Sun Disk of Ra and the Great Pyramid of Giza. ( see the A.M.O.R.C. Ancient Mystical Order of the Rose-Crois )
When a high adap of any these occult groups supposedly reached the highest levels of spiritual consciousness they become guides of the spiritual evolution of mankind, guiding us into the Occult New Age of Aquarius under the One World Government in a New World Order or Golden Age. ( of Lucifer ).
When a high member reaches the highest levels of spiritual consciousness they are considered one of the Ascended Masters when they die, and at death are dressed in a Roman Toga . This is why I Believe Charles T.Russell was still a high member at his death.
It's also why members of Freemasons and Rosicrucians funded the Statue of George Washington - with him dressed in a Roman Toga. ( at the Capitol Building) Another Occult Ascended Master to guide us from beyond.
