The term “Colossian” refers to anything related to the ancient city of Colossae, which was located in what is now Turkey. It is most commonly used in a biblical context to describe the inhabitants of Colossae or to refer to the New Testament book known as the Epistle to the Colossians, which is a letter written by the Apostle Paul to the Christian community in that city. Thus, “Colossian” can denote aspects of the culture, theology, or individuals associated with Colossae.
