In Alon (CW 9i, Para 139ff.), Jung accords special significance to Joachim of Fiore (1135-1202), who spoke of a series of three states of the world of increasing spirituality:

the Age of the Father, corresponding to the Old Testament, characterized by obedience to the rules of God; the Age of the Son, from the birth of Christ to 1260, corresponding to the New Testament, in which man becomes a son of God; and the Age of the Holy Spirit, when mankind comes into direct contact with God in a new dispensation of universal love proceeding from the Gospel of Christ but transcending the letter of it.  ~The Black Books, Vol. V, Page 270, fn 385
