The history of wiki websites specifically related to Christianity is much more recent than that of wikis in general. A wiki website is a site that allows users to add content, as on an internet forum, but also allows anyone to edit the content.
Wikipedia, with over a million articles, is the most well-known wiki website and is a testimony to the effectiveness of wikis in allowing exhange of information through collaborative effort. However, it also leads to politically correct manipulation of articles on or dealing with Christianity that could oftentimes lead to censoring of pertinent information on the subject.
In recent years, in response to some of these criticism, small numbers of Christian wiki websites have been setup. The first religious wiki was Why Clubbet although this has been called a failure by some. Currently the largest Christian wiki is WikiChristian which aims to be a major reference site for all topics relating to Christianity. Due to massive vandalism in May 2009 the pages were locked and the wiki is currently inactive regarding editing. OrthodoxWiki, for the Eastern Orthodox church and Theopedia, for evangelical Bible-based Christians are two denomination-specific Christian wikis. CARMPedia at www.carmpedia.com was a relative new-comer, but no longer exists. Jesuspedia is a small but growing Christian wiki encyclopedia, built upon the Bible, that affirms its unity with all of God's children.
Why Clublet was the first religious wiki. It has been described as a failure. Between September 1 2005 and November 11 2005, its recent changes page showed a total of 17 posts.
WikiChristian (www.wikichristian.org) is the largest wiki specifically related to Christianity on the internet. It was set-up in late 2004 by an American called Prab R. Tumpati. Shortly after, it was joined by Graham Grove in Australia and from there the site has grown. It was set up in the hope that it would become a useful reference on any topic related to Christianity. Articles do not need to be of a neutral point of view - the author can voice an opinion as long as the author of the article makes it clear what his or her background is. As of May 2012, the wiki seems to be inactive regarding article editing. The maximum range of all recent changes shows only new user account creations. Editing of articles appears to be restricted to only administrators. This wiki intends to be a reference point for historical information, historical texts, song lyrics and personal testimonies of Christians.
- Main article:Conservapedia
A conservative Christian version of Wikipedia which is slowly but surely becoming one of the most if not the most prominent Christian oriented wiki. Although not oriented directly to Christian thought and themes, Christian subjects are a prominent part of the wiki and are treated with respect.
Theopedia at www.theopedia.com is a Christian wiki where content is expected to conform to a Protestant and Bible-based approach to Christianity. It was set up by an American from Ohio named Aaron Shaf.
OrthodoxWiki at www.orthodoxwiki.org is a wiki specifically for all issues related to Eastern Orthodox Christianity. It was inaugurated in November 2004 and has grown considerably with many active contributing users.
CARMPedia, which used to be at www.carmpedia.com, is described as "a short-lived wiki created by CARM," no longer in existence. It was set up by the well-known Matt Slick, who is the founder of the popular Christian apologetics website CARM. It was similar to Theopedia in that users were expected to agree to a Protestant and biblically-based approach to Christianity.
