After the Council of Nicaea, all the same questions that had been asked of the Son of God, were now asked of the Holy Spirit. Is the Holy Spirit divine, and worthy of worship? Does worship of the Holy Spirit compromise monotheism? Some who reluctantly accepted the divinity of the Son still refused to accept the divinity of the Spirit, and so they continued to reject the doctrine of the Trinity - these were called "Spirit-fighters." This controversy led to the Second Ecumenical Council of Constantinople in the year 381 AD, and to the completion of the Nicene Creed.
