I visited the cemetery about 30 years ago. There was no Masonic lodge at that time. I went into the cemetery office and after much begging, was shown the cemetery records for the plot. There were many names of people that had been buried there in the plot that did not have tombstones. The pyramid only lists a few names. The pyramid was not planned by Russell, but was built after his death, in 1919, as I remember. I am not sure about Russell's tombstone, but I doubt that Russell had planned that either. Is there any photograph of a different tombstone that preceded the present one?
The cemetery office had the burial record for Russell, but all I can remember the cause of death listed was incorrect. One thing that is curious is that on the cemetery records, for the officers at that time, the signatures of a man named Bohnet and Spill show up. Bro. Bohnet and Dr. Spill both worked for Russell, and yet they also were officers for the cemetery. This shows that there was some connection between the Watch Tower and the cemetery. Does anyone have clearer information about the cemetery? My memory is that cemetery office had told me that the Watch Tower had once owned the cemetery or the plot of land.
Russell never called himself "The Laodicean Messenger". This comes from the book of Revelation. There were messages to the angels of the seven churches, one of which was Laodicea, the last of the seven churches. Russell taught that the seven churches represent seven stages of the church during the Gospel Age, and that the angels, which can also be translated "messenger" represents human messengers which Christ used to give messages to the Christian church.
The seven messengers is covered quite thoroughly in the book "The Finished Mystery", written by Woodworth and Fisher, not Russell as the book claimed. There Russell is called The Laodicean Messenger. In the years after Russell's death, Russell was canonized by the Society, and glorified. After his death, he was called "That servant" as well. Russell never openly admitted to being "that servant", although it is likely that he believed so.
The canonization of Russell and the pyramid and tombstone are a reflection of the need for Rutherford to establish the legitimacy of his authority. Russell had never designated a successor, and from his Will and Testament for the Society, it is clear that Russell did not plan for one-man rule. Rutherford gained the Presidency by behind-the-scenes political maneuvering and bullying and other suspicious activities, followed by his illegal removal of Board members who did not agree with him. In elevating Russell and thus the Society that he led for many years, Rutherford was able to enhance his own position. When Rutherford's authority was in place, he initiated the decanonization of Russell, and condemned the very "creature worship" that he fostered.
Although Russell had his faults which cannot be excused, the present anger toward Russell is misplaced. Until the internet there was never any hint among the Bible Students/JWs of a Masonic connection, which is based on speculation and ignorance of the true history behind the JWs. Although the pyramid at the tombstone resembles the Great Pyramid, it likely represents the Church class glorified. See the Chart of the Ages, which has many pyramids, including pyramids which represent the Church class, Little Flock.
