Lou Engle is an American Charismatic Christian leader, best known for his leadership of The Call, a program that hosts twelve-hour prayer rallies, and his association with prominent members of the Christian Right. Engle was a senior leader of the International House of Prayer and has assisted in the establishment of several smaller "houses" of prayer.
Engle has been organizing large prayer rallies since 1999, with hundreds of thousands of people in multiple countries participating. The size of these events, in addition to Engle's political statements, has raised his prominence among the Christian Right. Journalist Bruce Wilson referred to Engle as "the unofficial prayer leader of the Republican Party." In addition to these meetings, Engle established several small houses of prayer through his Justice House of Prayer ministry. These ministries are often located near prominent landmarks, such as Harvard University or the United States Supreme Court. The locations of the ministries are strategically chosen, to specifically contend issues such as abortion.
In 2008, Engle focused the attention of his prayer groups towards supporting California's Proposition 8 ballot measure. He organized 24-hour protests in front of the United States Supreme Court, whereby the young participants symbolized the powerlessness of terminated fetuses by placing tape over their mouths with the word "LIFE" written on it.
Engle has focused on the issue of abortion. He frequently encourages his audiences to pray that the Roe vs Wade Supreme Court ruling will be overturned and to vote for "pro-life" political candidates. Taking a firm stand on issues traditionally associated with the Christian Right, Engle's events have drawn support from Evangelical leaders such as Mike Huckabee and Tony Perkins. He criticized other Evangelical leaders regarding the issue of political correctness.
