And in Antioch the disciples were first called Christians. – Acts 11:26
The word “Christian” is nowhere used in the Bible as anything other than a noun. However, in American culture we constantly use “Christian” as an adjective or adverb to describe things such as music, movies, books, character, charitable acts, and so many other things. The great danger in this is the temptation to replace our genuine faith in Christ with traditions steeped in culture rather than God’s everlasting truth.
