>snip<
Camping teaches that a Biblical calendar has been hidden according to Daniel 12:9, Revelation 22:10 detailing the imminent end of the world (with alleged Biblical evidence pointing to the date for the Rapture as May 21, 2011);<8> of the "end of the church age" (which asserts that churches are no longer the vehicle used by God for salvation, 1 Peter 4:17);<9> and of predestination (Ephesians 1:4-5), according to which God determined before the beginning of the world which individuals are to be saved. In Camping's latest publications, he states that May 21, 2011 will be "the first day of the Day of Judgment"<10> and October 21, 2011 will be the end of the world.<11> Critics call Camping a "date-setter" following his own method of Biblical interpretation. Camping maintains that he follows the Bible's method of Biblical interpretation.<12>
Camping does not consider Family Radio a church and does not claim ordained or hierarchical authority within a church or institution. Camping claims that the church institutions do not employ the Bible alone as the sole authority. According to Camping, each church or denomination has its own unique set of doctrines and hermeneutics, which dictate how they understand the Bible. Family Radio's sole focus on the Bible is what he believes distinguishes it from churches. Recently, as his predicted Judgment Day (May 21, 2011) draws near, Family Radio has become affiliated with eBibleFellowship.com, another Bible-based ministry. Followers continue to listen to Camping despite the fact that he was wrong in his previous prediction of the end of the world. In his book 1994?, he claimed there was a very high likelihood that the world would end in September, 1994, although he did acknowledge in the book "the possibility does exist that I could be wrong."<13> He makes no mention of this failure when establishing his new claims of the end of the world in October, 2011. Camping has received criticism from a number of leaders, scholars, and laymen within the Christian community for his predictions on when the Rapture will take place. His critics argue that Jesus Christ taught that no man knows the day or the hour of the Lord's return.<14><15>
