The word "Melchizedek" is used in at least five different meanings.
- Melchizedek was the name of a Hebrew King / patriarch, who lead an exemplary life and was well respected. Legend has it that as a reward, just like Enoch and Isaiah, he was taken to heaven.
- The name Melchizedek can also be encountered as an ascended master. Some believe it is the same Hebrew King who became an ascended master.
- Melchizedek also is the name of one of the highest ranking Angels. Some claim that he is the same Hebrew King, and that God made him one of the Angels. Often there are a lot of parallels with Metatron in this respect.
- In some sections of Jewish and Christian mysticism, Melchizedek is the name, not of one, but of a whole rank or legion of Angels. So you would have the Melchizedek, just like you have, e.g., the cherubim, the virtues, etc… Their main function would be as angelic messengers. The word Melchizedek is used in this meaning in both the "Book of Urantia," and the "Keys of Enoch."
- Last but not least, Melchizedek is used, too, as the name of a race of higher dimensional beings. Drunvalo Melchizedek, from the Flower of Life organisation, is said to be such a "thirteenth dimensional" being, who is currently living in a third-dimensional incarnation.
