Goodwin translated and printed a part of the "Stratagemata Satanae" (March 1648) of Acontius under the title "Satan's Stratagems; or the Devil's Cabinet-Councel discovered", with recommendatory epistles by himself and John Durie. Acontius, an advocate of religious tolerance, was now stigmatised by Francis Cheynell as a 'sneaking Socinian'. Cheynell sought in vain in the Westminster Assembly to obtain a condemnation of Goodwin's book, but printed (1650) his thoughts about it by request. The translation was reissued with a new title, "Darkness Discovered; or the Devil's secret Stratagems laid open" (1651).
