Open-air preaching

Public proselytization of a religious message to crowds of people in open places

Open-air preaching, street preaching, or public preaching is the act of evangelizing a religious faith in public places. It is an ancient method of proselytizing a religious or social message and has been used by many cultures and religious traditions, but today it is usually associated with evangelical Protestant Christianity. Supporters of this approach note that both Jesus and many of the Old Testament prophets often preached about God in public places. It is one of the oldest approaches to evangelism.
