A megachurch is a large church characterized by weekly attendance of 2000 people or more, an active congregational community, a large number of outreach and social ministries, and several other criteria. While some Catholic churches may fulfil most of the criteria for a megachurch, the term is usually only applied to Protestant churches.
A substantial number of megachurches are non-denominational, and most that are associated with denominations are Baptist, Evangelical, or Pentecostal, as opposed to more traditional denominations such as the United Methodist Church.
- Pastor Rick Warren's Saddleback Church in Lake Forest, California, is a leading Baptist megachurch in the United States, with a weekly attendance of just under 20,000, making it about the eighth largest congregation in the nation.
- Joel Osteen's Lakewood Church in Houston, Texas draws 40,000 in weekly attendance. Lakewood Church is a former stadium equipped with lights and large flatscreen televisions. It manages a multi-million dollar television ministry. The largest church in America, it is also among the best examples of a megachurch.
