There has already been a lot of research done on Christianity and homosexuality. According to Whitehead (2012), only 5.7% of churches have chosen to establish a formal statement welcoming homosexuals into their church, and evangelical churches are among the least likely to have such a statement, a low 3.9%. Cadge, Day, and Wildeman (2007), found that there are a variety of factors that might influence a particular congregation's approach to the topic of homosexuality, including the church's prior involvement in social justice issues, the presence of homosexual individuals within the community and the availability of denominational guidelines for dealing with them
