Colossians 1:18 change wording from "He is the originating authority, the firstborn from of the dead ones, so he has first place among all things." to what you see now. This is closer to the Greek. The phrase "originating authority" is interpretive and not literal.
Colossians 1:5 original wording: "You first heard about this confident expectation in the word of truth, the gospel." This fits the Greek better specifically the aorist.
