Roland Allen was an influential English Anglican missionary, theologian, and author. He is best known for his challenging writings on missionary strategy, particularly advocating for the establishment of indigenous churches that were self-supporting, self-propagating, and self-governing. His most famous work, "Missionary Methods: St. Paul's or Ours?", critiques Western missionary practices and calls for a return to the principles he found in the New Testament. Allen's radical ideas were often overlooked during his lifetime but experienced a significant revival in the later 20th century, profoundly shaping modern missiology.
