8 AGES AND EPOCHS (Define)
"The Faith is divided into three Ages: the Heroic, the Formative, the Golden Age, as has been outlined in His Writings. The Heroic Age closed with the Ascension of Abdu'l- Baha. The Formative Age is divided into epochs. The first epoch lasted 25 years. We are now actually in the second epoch of the Formative Age. How long the Formative Age will last is not known, and there will probably be a number of epochs in it. (3:1)
