What does "Godhead" mean?

"The term “Godhead” is used three times in the Bible:

“Forasmuch then as we are the offspring of God, we ought not to

think that the Godhead is like unto gold, or silver, or stone, graven by art and man’s device” (Acts 17:29, KJV).
“For the invisible things of Him from the creation of the world are clearly seen, being understood by the things that are made, even His eternal power and Godhead; so that they are without excuse” (Romans 1:20, KJV).
“For in Him dwelleth all the fulness of the Godhead bodily” (Colossians 2:9, KJV).

Other translations (NASB, NIV, ESV) use different terms in place of “Godhead” – divine nature/being (Acts 17:29), divine nature (Romans 1:20), and deity (Colossians 2:9). These are helpful in understanding the meaning of the term.

“Godhead” is about nature or possessing the characteristics of God.

Another term that may be easier to understand would be “Godhood.” This would be similar to “manhood” or “brotherhood” – possessing the characteristics of “men” or “brethren.” Those in the “Godhead” are part of the “Godhood” – possessing the characteristics of God."
