Lineage has been a frequent discussion, and most certainly a heated debate. Lineage, via the Golden Dawn current, doesn’t exist in a “first class” aspect. Most, if not all, modern temples are third and sometimes fourth generation offshoots of the original Isis Urania, or Temple LLL.
There are few instances which a surviving temple or original Order/Temple charter exists. One such instance of this is the Whare Ra Temple.
Although these few exist, that does not mean, by any means that these temples are “Official” or that the materials they teach are “original” to the Order of System of the Golden Dawn or the Rosae Rubae. Often temples use materials which are either published, or have reworked them to fit their temples needs via previous temple materials from other orders, temples, or research. This is a common practice with all old “official” Golden Dawn temples. Each temple started because at one point there was a basis of belief that something needed changed or something else needed to be implemented. The likeminded individuals set out and created their own temple, still yet using some of the original documents, and adding their own.
An example of this is the Horus Temple, and the Ptah temple from the United States. Each of these temples, although governed by the Ahathoor Temple, in Paris via Moina Mathers, did not conform neither to the Alpha Omega Temple nor to the temples themselves. Each had in essence the same materials, and yet completely different. A grand example of this is the Neophyte initiation. While the Ptah temple had followed the Alpha Omega format, the Horus temple removed several aspects of the initiation to simplify it.
Simply put, true linage is found within the adept. It is found in the practice and dedication of not only one adept, but the whole alike. Bickering about whom has what charter is pointless. That “charter” does not make a difference to the GD Current. Not one iota. In closing, “Lineage is found at the Heart of the Adept”. Nothing more, nothing less.
