Speaking of Christ, Colossians 1:18 says
Col. 1:18 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. (ESV)
The word in that passage for “all things” is pasin in the Greek, from the word pan, which means “all.” This word choice means that nothing is excluded or excepted. By His position in creation (Col. 1:16), by virtue of the truth that all things were made FOR Him, and by His activity in sustaining all things (Col. 1:17), Christ has the right to be preeminent over EVERYTHING.
The word for “preeminence” is the Greek word proteuon, which is a verb that means to “hold the first place”, or “to be the priority of.” Christ is the priority, then of all creation. He is and must be of first importance.
By rights, then, Christ should be the most important thing, the priority, not only of the church (as in Col. 1:18) but of all of creation, including His creatures.
