Reasons to Believe (RTB) is a nonprofit organization that promotes day-age forms of old Earth creationism. It was founded in 1986 by Hugh Ross, a Canadian-born astrophysicist and creationist Christian apologist. Former Vice-President of Research and Apologetics, Fazale Rana, was named President and CEO in July 2022. Reasons to Believe aims to use science as a means of evangelism. The organization publishes articles, books, and audio programs about topics related to science and Christianity. It also produces video and multimedia content and hosts events where RTB speakers discuss science and apologetics. The organization integrates science, theology, and philosophy to address topics such as the existence of God and the Bible’s reliability. Reasons to Believe is a member of the Evangelical Council of Financial Accountability and the Independent Charities of America. RTB uses the words of 1 Peter 3:15-16 as the organization’s core values and ministry goal. Through its Reasons Institute program, Reasons to Believe offers courses in science apologetics at educational institutions such as Biola University, Northern California Bible College, and Erskine Theological Seminary. Reasons to Believe founded RTB Press in 2013 to be an in-house publisher of books by RTB scholars. More than 25 books have been published through RTB Press. The organization previously published twelve books through Baker Publishing Group. As of February 2023, RTB has six in-house research scholars: Hugh Ross, Fazale Rena, Jeff Zweerink, Kenneth Samples, George Haraksin, and Dave Rogstad. RTB also organizes a scholar community with 170 members that studies various topics, including apologetics, earth sciences, and theology and participates in workshops organized by RTB. As of February 2023, there are nearly 50 RTB Chapters spread across the United States that meet regularly in their area to discuss science and faith topics. International chapters include several in Canada and India.
