Jesus is the Head of the Church positionally but not in reality because if He was truly the Head of the Church there would be no such thing as Calvinism nor Cessationism nor false doctrines in other Camps, He would be Lord over everything that needs to take place in His Body the Church the New Creation but obviously this is not the case. And all of this will be revealed in great details in the Judgment Seat of Christ starting with 1st Corinthians 3:10-15.
