Writings from the Dead Sea Scrolls and the Nag Hammadi Codices show that for two centuries before and after Jesus Christ, certain religious groups practiced rituals that included anointing patrons and the receiving of celestial robes. Teaching about the use of secret names and tokens took place along with passing through the temple veil into the presence of God. Revelations of the secrets of creation and the exaltation and deification of individuals were presented. Ascension into various levels of heaven representing different degrees of glory was a part of the ceremony. The need for moral purity was taught, and Eternal Marriages were performed.
