Christians have used many different approaches to spread Christianity via the practice of evangelism. Christianity began with only a few different evangelistic approaches, but over the years, many different forms of evangelism have been employed by various groups to spread their faith. Many of these forms of evangelism are often employed in only certain parts of the world by Christians in different geographical areas. In particular, most new approaches to evangelism today have arisen out of Europe or the United States, especially when new technologies are used for the effort of evangelism.

Open-air preaching

Open-air preaching is an approach to evangelism characterized by speaking in public places out in the open, generally to crowds of people at a time, using a message, sermon, or speech which spreads the gospel. Supporters of this approach note that both Jesus and many of the Old Testament prophets often preached about God in public places.http://www.biblebelievers.com/StreetPreaching2.html "OPEN-AIR PREACHING, A SKETCH OF ITS HISTORY AND REMARKS THEREON", Charles H. Spurgeon. It is one of the oldest approaches to evangelism.Spurgeon, Pg. 234

During Protestant Reformation, open-air preaching was often employed by Protestants throughout EuropeSpurgeon, Pg. 235 who could not always preach inside churches, which were mostly Catholic.Spurgeon, Pg. 236 Open-air preaching in Europe continued during the rise of Puritanism and other Protestant movements. It was often used in Pastoral environments as well as in cities, the former sometimes due to a desire to avoid the authorities,Spurgeon, Pg. 241 and the latter because, for one reason, it could reach eccentric people living in cities who would not otherwise hear the gospel.Spurgeon, Pg. 257

In the time period of the late 19th century and early-to-mid-20th century many famous open-air preachers in the United States began to preach, such as Billy Sundayhttp://www.christianitytoday.com/history/special/131christians/sunday.html "Billy Sunday Salty evangelist", ChristianityToday.com and Billy Graham. Graham in particular used a combination of open-air preaching and the recent advent of televangelism to broadcast his sermons, which often took place in large venues such as stadiums, to large portions of the world and millions of Americans.

Early Methodist preachers John Wesley and George Whitefield preached in the open air, which allowed them to attract crowds larger than most buildings could accommodate.JOHN WESLEY.; G. Holden Pike's History of the Great Methodist and His Associates, New York Times The first Great Awakening , Tony Cauchi, Jamaica Gleaner Wesley declared, "I am well assured that I did far more good to my Lincolnshire parishioners by preaching three days on my father's tomb than I did by preaching three years in his pulpit ... To this day field preaching is a cross to me, but I know my commission and see no other way of preaching the gospel to every creature."

Trickle-down evangelism

Trickle-down evangelism is an approach to evangelism primarily concerned with converting high-ranking members of a society, so that their influence can serve to help spread Christianity throughout the society in question. It was practiced especially often during the Middle Ages.

Trickle-down evangelism was practiced throughout China multiple times during the Middle Ages, with examples such as converted or sympathetic officials helping the Jesuits or other parts of the Catholic church spread,https://www.newadvent.org/cathen/03669a.htm "The Church in China", Written by Henri Cordier. Transcribed by M. Donahue. The Catholic Encyclopedia, Volume III. Published 1908. New York: Robert Appleton Company. Nihil; http://www.christianitytoday.com/workplace/articles/wycliffingworkplace.html "Wycliffing the Workplace … and Other Evangelism Lessons from the Missionary Trenches", FaithInTheWorkplace.com, Randy Kilgore, October 1, 2004, Retrieved May 27, 2007 or the expedition of Marco Polo resulting in the Mongol ruler of China Kublai Khan inviting the Pope to send "teachers of science and religion" to China."Trickle-Down Evangelism", Ralph R. Covell

Trickle-down evangelism was also applied often in European areas during ancient times, such as in the northern Sweden area, as the Catholic Church tried to send missionaries into the area.

Door-to-door evangelism The Bible records that Jesus sent out his disciples to evangelize by visiting peoples homes in pairs of two believers (cf. ). In the same text, Jesus mentioned that few people were willing to evangelize, despite there being many people who would be receptive to his Gospel message. As such, door-to-door preaching is an approach to evangelism where a Christian will go from household to household in a certain area to evangelize to residents, often in conjunction with passing out gospel tracts. Jesus often went into other people's homes during his own ministry, and according to The Encyclopedia of Protestantism, it is a very important approach to evangelism.Barret, Pg. 721

One of the first modern large-scale uses of door-to-door preaching was when the Oriental Mission Society attempted to visit the homes of an entire nation, by visiting 10.3 million homes in Japan from 1912 to 1917. The international organization Every Home for Christ began door-to-door preaching in 1953 throughout many countries, and as of 2010, total home visits by their members became 1.3 billion. Many local parishes and churches worldwide use this approach to evangelism. Methodist churches aligned with the holiness movement engage in door to door evangelism and in this tradition, it is frequently referred to as "calling".

Groups such as Jehovah's Witnesses and members of the LDS movement are famous in particular for spreading their beliefs by door to door evangelism at people's homes, often in pairs or small groups. Both groups' main organizations use door-to-door preaching to a great extent. Full-time missionaries of the Church of Jesus Christ of Latter-day Saints use this, and other techniques, to find people to teach.Davies, Pg. 1316

Ashes to Go evangelism on Ash Wednesday

Since 2007, some members of major Christian Churches in the United States, including Lutherans, Catholics, Anglicans and Methodists among others, have participated in 'Ashes to Go' activities, in which clergy go outside of their churches to public places, such as city centres, sidewalks and railroad stations, to distribute ashes to people on Ash Wednesday, the first day of Lent, the penitential season in the Christian liturgical calendar. The Anglican priest Emily Mellott of Calvary Church in Lombard took up the idea and turned it into a movement, stated that the practice was an act of evangelism. Anglicans and Catholics in parts of the United Kingdom such as Sunderland, are offering Ashes to Go together: Marc Lyden-Smith, the priest of Saint Mary's Church, stated that the ecumenical effort is a "tremendous witness in our city, with Catholics and Anglicans working together to start the season of Lent, perhaps reminding those who have fallen away from the Church, or have never been before, that the Christian faith is alive and active in Sunderland." The Catholic Student Association of Kent State University, based at the University Parish Newman Center, offered ashes to university students who were going through the Student Center of that institution in 2012, and Douglas Clark of St. Matthew's Roman Catholic Church in Statesboro, among others, have participated in Ashes to Go. On Ash Wednesday 2017, Father Paddy Mooney, the priest of St Patrick's Roman Catholic Church in the Irish town of Glenamaddy, set up an Ashes to Go station through which commuters could drive and receive ashes from their car; the parish church also had "drive-through prayers during Lent with people submitting requests into a box left in the church grounds without having to leave their car". Reverend Trey Hall, pastor of Urban Village United Methodist Church, stated that when his local church offered ashes in Chicago "nearly 300 people received ashesincluding two people who were waiting in their car for a stoplight to change." In 2013, churches not only in the United States, but also at least one church each in the United Kingdom, Canada and South Africa, participated in Ashes to Go. Outside of their church building, Saint Stephen Martyr Lutheran Church in Canton offered Ashes to Go for "believers whose schedules make it difficult to attend a traditional service" in 2016. In the United States itself 34 states and the District of Columbia had at least one church taking part. Most of these churches (parishes) were Protestant Episcopal, but there were also several Methodist churches, as well as Presbyterian and Catholic churches.

Evangelizing through a sermon

Many churches regularly have a gospel message preached in a sermon. Often, this will include an altar call where people are invited to come forward to the chancel rails or mourner's bench and accept Christ; the tradition of altar calls is practiced by many evangelical denominations such as the Methodist and Baptist Churches.

Many Reformed Christians object to it on the grounds that they believe it creates false conversions.http://www.9marks.org/partner/Article_Display_Page/0,,PTID314526|CHID629094|CIID1804792,00.html "Altar Call Evangelism", Paul Alexander

Lifestyle evangelism

Lifestyle evangelism is an approach to evangelism characterized by someone demonstrating their faith by their actions in the hope that people around them will be impressed with how God affects that person's life, and become a Christian. According to The Encyclopedia of Protestantism printed in 2004, approximately 100 million people use this approach to evangelism.Barret, Pg. 721

Supporters of this approach to evangelism often cite Matthew 5:16 as a proof verse."The Evidence Bible", Ray Comfort, Bridge-Logos Publishers, 2003, p. 842"1,001 Practical Ways to Share God's Love", Richard Lee Supporters also often point out that Jesus drew people to God by showing them kindness and performing good deeds, while detractors sometimes note that people may not realize one's good behavior is due to Christianity. Supporters claim this is more effective than direct evangelism because of the perception that it is harder to live "righteously" than to preach a sermon.

Friendship evangelism

Similar to lifestyle evangelism, friendship evangelism is an approach to evangelism characterized by Christians developing relationships with people in order to show them kindness and talk to them about God eventually. Supporters sometimes say that Jesus related to those who took an interest in him as friends, or that it is more effective than other methods of evangelism which are seen as less personal. This approach is also known as "loving someone into the kingdom". Opponents hold that friendship evangelism contrasts with the approach of Jesus, Paul and the apostles towards preaching the gospel. Missionary dating takes this a step further and Flirty Fishing takes it to an extreme.

Child evangelism

The child evangelism movement is a Christian evangelism movement that was begun in the 20th century. It focuses on the 4/14 Window which centers on evangelizing children between the ages of 4 and 14 years old.

Creative evangelism

This approach to evangelism is where the creative arts (such as music, visual art, drama, film) are used to present a gospel message.Saltmine Creative Arts , retrieved October 1, 2006 Examples include Wendy Alec's novel "The Fall of Lucifer", Christian rock band Delirious? and Johann Sebastian Bach's musical composition "Matthäuspassion" (Saint Matthew Passion).Barret, Pg. 720 However, some ministries refer to this kind of evangelism as simply the practice of finding creative ways to evangelize.
