The influence of the Plymouth Brethren upon evangelical Christianity exceeds their relatively small numerical proportion. The movement today has many small assemblies in Great Britian, Canada and the US, New Zealand and Australia, then the European, African and Asian continents.
PB missionaries have had a major impact on missions around the world - specifically in central sub-Saharan Africa and Asia. They have been productive writers and publishers including George Cutting's Safety, Certainty, and Enjoyment, and many tracts and correspondence courses in many languages from Emmaus Bible College Trinity School Of Apologetics.
Many leaders of the contemporay evangelical movement have come from PB backgrounds including Geoff Tunnicliffe, CEO of the World Evangelical Alliance, the late British scholar FF Bruce, Brian Maclaren of the emerging church movement, 1950's Auca missionary martyrs Ed McCully, Jim Elliot, and Peter Fleming, and the late great preacher Dr. Harry Ironside. In recent years Alex Strauch's book, Biblical Eldership, has become a manual used in evangelical circles outside the Brethren movement. J.N. Darby, one of the founders of the movement, is sometimes credited with beginning the so-called "dispensationalism" movement that is now promoted through Dallas Theological Seminary and is wide-spread in contemporary evangelicalism. They have also made significat contributions in Christian Apologetics.
The Brethren have made significant contributions to Christian hymnody, particularly on the subect of the person and work of Christ, and hymns for use at the Lord's Supper.
Aleister Crowley on occassion ascribes his occult interests to the rigid theological dogma of his childhood in a Plymouth Brethren family in Warwickshire, in particular his mother's constant admonishments that he was the Beast of Revelation and that he would go to hell for his behaviour.
