Quintessence is not a biblical word but a useful concept — the purest, most distilled essence of something, free from any alloy or admixture. The medieval Latin quinta essentia (fifth element) named the heavenly substance beyond the four earthly elements. Christianly applied, Christ is the quintessence of God’s glory: "Who being the brightness of his glory, and the express image of his person, and upholding all things by the word of his power" (Hebrews 1:3). Whatever God is in essence, Christ is in incarnate form: "in him dwelleth all the fulness of the Godhead bodily" (Colossians 2:9). To see Christ is therefore not to see a piece of God or a representation of God — it is to see God Himself, purely, fully, undiluted.
Purest distilled essence of something.
The purest, most concentrated essence; not biblical vocabulary but useful for what Hebrews 1:3 says of Christ — He is the brightness of God's glory and the express image of His person, the quintessential revelation of who God is.
Hebrews 1:3 — "Who being the brightness of his glory, and the express image of his person, and upholding all things by the word of his power."
John 14:9 — "He that hath seen me hath seen the Father."
Colossians 1:15 — "Who is the image of the invisible God, the firstborn of every creature."
Used loosely in modern English, severed from its precise meaning of distilled-essence.
When we say Christ is the quintessence of God's glory, we mean Hebrews 1:3 precisely: He is not a sample of God but the purest distilled revelation of who God is. To see Christ is to see the Father, undiluted, unshadowed, perfect.
