What does it mean that Christ is 'firstborn of all creation'?

It means Christ holds the office of firstborn over creation — not that he was the first created being.

"He is the image of the invisible God, the firstborn of all creation... and he is the head of the body, the church. He is the beginning, the firstborn from the dead, that in everything he might be preeminent." — Colossians 1:15, 18

The Greek word is πρωτότοκος (prōtotokos, G4416). The early church had to answer a specific challenge about this phrase from the 4th-century Arian controversy — teachers who argued that "firstborn of all creation" meant Christ was the first created being. The councils (Nicaea, then Constantinople) rejected that reading. The text itself points a different way.

The key is how the Bible uses "firstborn" before Paul ever writes Colossians.

In the Torah, the firstborn (בְּכוֹר bekhor, H1060) receives a double portion of inheritance (Deut 21:17), is consecrated to the LORD (Exo 13:2), and eventually stands in a priestly role that the tribe of Levi later absorbs (Num 3:11–13). The office is defined by privilege and representation, not just by chronology.

But the Bible also keeps transferring the office. Isaac displaces Ishmael. Jacob displaces Esau. Ephraim is blessed ahead of Manasseh when Jacob deliberately crosses his hands (Gen 48:14, 18–19). Reuben forfeits his firstborn status to Joseph, Judah, and Levi (1 Chr 5:1–2). Seven older brothers of David are all passed over for the youngest (1 Sam 16:1–13).

Then Psalm 89:27 does something decisive with the word. Speaking of David — Jesse's youngest son — God declares:

"Also I will make him the firstborn, the highest of the kings of the earth." — Psalm 89:27

The Hebrew verb is natan (H5414, "to give, appoint, make"). David was not born firstborn. He is appointed firstborn. The word is officially reframed: from birth-order to office-of-election.

The Septuagint translates this psalm (as Psalm 88:28 in the Greek numbering) using πρωτότοκος — the exact word Paul will later use of Christ. So when Colossians 1:15 says Christ is "firstborn of all creation," Paul is not inventing a new metaphor. He is continuing the Davidic covenant vocabulary. Christ is what David typified: the one appointed firstborn by divine decree, the one through whom the whole inheritance flows to everyone else.

Colossians 1:18 clinches this. The same sentence says Christ is "the beginning (ἀρχή), the firstborn from the dead, that in everything he might be preeminent." The firstborn office is twofold: over creation, and over the resurrection-harvest. And the purpose clause — hina gēnētai en pasin autos prōteuōn — makes explicit that "firstborn" is being used as a rank word, not a timeline word. "That in everything he might be preeminent."

Revelation 1:5 seals it with a compound title that reworks Psalm 88:28 LXX: "the firstborn of the dead, and the ruler of the kings of the earth." The psalm said firstborn + highest of kings of the earth. Revelation says firstborn of the dead + ruler of kings of the earth. Same vocabulary, extended to resurrection.

One more note, because the New Testament adds something the Psalms didn't quite reach. In Hebrews 12:23, the word becomes plural: "you have come... to the assembly of the firstborn ones (πρωτοτόκων) enrolled in heaven." The one firstborn has brothers (Rom 8:29), and the brothers are also firstborn. The office that Old Testament narratives kept displacing from one person to another is, in the end, multiplied — every person in Christ becomes firstborn with him.

So "firstborn of all creation" does not mean Christ was made. It means he was appointed — the preeminent one, the office-holder, the Davidic firstborn completed in the one who makes all his brothers firstborn too.
