Despite the obvious risks involved, in 1613 Helwys and twelve Baptist émigrés returned to England and founded the first Baptist congregation on English soil in Spitalfields, east London. They brought "The Mistery of Iniquity" with them and one copy of it was delivered to King James I, with a handwritten inscription arguing for liberty of conscience. "The King," Helwys said, "is a mortal man, and not God, therefore he hath no power over the mortal soul of his subjects to make laws and ordinances for them and to set spiritual Lords over them." Helwys and other Baptists were thrown into Newgate Prison, where they wrote a petition to the King.
