Distinguish before comparing
The Nag Hammadi Melchizedek is ancient and fragmentary. Grumbine's Melchizedek is a 1919 esoteric interpretation. Shared names do not make them one doctrine, and missing ancient text cannot responsibly be completed with modern speculation.
Activity
Two-source ledger
Practise source literacy before drawing spiritual meaning.
Make two headings: ancient fragment and 1919 interpretation.
Under the first, write: incomplete priestly/revelatory tractate; meaning limited by damaged text.
Under the second, write: modern esoteric system; OCR variable; not standard biblical scholarship.
Write the comparative question between them rather than underneath either: how might purpose become service without rank?
Reflect
How does clear separation make comparison more trustworthy rather than less meaningful?
Keep agency: Do not infer a hidden lineage, office or personal initiation from either source.
