About the contextual problems associated with Trinitarian interpretations of Colossians 1:15-18 and how their own theological preconceptions prevent them from seeing what Paul is obviously talking about. One thing is for certain - Paul isn't talking about the Genesis act of creation.

The firstborn of the dead, Jesus, became pre-eminent when God raised him from the dead and seated him at His right hand above all thrones, dominions, rulers, powers, and authorities. The Greek words ktisis/ktizo (creation/create) were used by Greeks to refer to the establishment of city states and kingdoms especially with respect to their authority structures which they were founded upon (see 1 Peter 2:13). This is what Paul has in mind at Colossians 1:14-16. He is discussing the risen Son's Kingdom into which we have been transferred and how these authority structures (thrones, rulers, etc.) were created in him when God raised Jesus from the dead and seated Jesus at this right hand giving him all authority in heaven and earth and subjected all rule, power, and authority to Jesus.

"the resurrection of Jesus Christ, who is at the right hand of God, having gone into heaven, angels and authorities and powers having been subjected to him." 1 Peter 3:22; see 1 Cor 15:24-28; Eph 1:20-21; Heb 1:4; 2:5-9.

Paul is talking about someone who BECAME pre-eminent (1:18; see Heb 1:4). A new creation is that which has been reconciled to God in His Christ (2 Cor 5:16-19). At Colossians 1:16, Paul is referring to God reconciling the world to Himself (v.20) in Christ and the creation of authority structure in the son (v.16) and his Kingdom (v.13-14) which God granted him (Luke 22:29) when He seated Jesus at His right hand giving him all authority in heaven and upon the earth (Matthew 28:19). The risen Jesus is Lord of all who obey and all who do not. God subjected all rule and power and authority to the risen Jesus until he puts his enemies under his feet (1 Cor 15:24-28; see Hebrews 2:5-9; Eph 6:12; 1 Peter 3:22).
