Men becoming gods is a True Ancient Christian Doctrine and the Apostolic and Church Fathers are a witness to this belief. It is also found today in the Catholic and Eastern Orthodox Churches.
Christ - a God Maker!!
One of the reasons why Christ was rejected by many of the Jews of his time, and after that time, was that he was seen as a man who sought to make himself a God, thus, he was rejected for being a "GOD MAKER!" Some of the Jews acknowledged Christ good works, but rejected Christ's claims: "...For a good work we stone thee not; but for blasphemy; and because that thou, being a man, maketh thyself God." Jesus reminded them of their own law that said "ye are Gods" (Psalms 82:6). This scriptures was used by a number of early to later Christians as proof texts for their own particular versions of the doctrine of deification.
