Note 1 at 1 Cor. 12:1: The Greek word used here for "spiritual" is "pneumatikos" and is used 26 times in the New Testament. It is the adjective of the Greek word "pneuma" (spirit) and is a word that is not used in the Septuagint (a pre-Christian Greek translation of the O.T.) or the Gospels but only in the post-Pentecost era. It is an antonym of the word "natural" (1 Cor. 3:1; 15:44) and applies to the spiritual realm of either God or Satan. It "always connotes the ideas of invisibility and of power" (Vine's, p. 64).

Note 2 at 1 Cor. 12:1: Paul wrote 1 Corinthians 12-14 to counter ignorance about spiritual gifts. This is the most complete expose on the matter in the Bible. Yet, sad to say, many people are still "in the dark" about spiritual gifts and the proper operation of them. A large portion of the body of Christ has believed that all these gifts passed away after the first century. That's even more ignorance than the Corinthians had.
