Institute for Religious Research

Institute for Religious Research Resources for Investigating Today's Competing Religious Claims From that time until his passing in November 2007, Luke P. Wilson was IRR’s Executive Director.

The Institute for Religious Research (IRR) is a nondenominational, evangelical Christian ministry of apologetics and discernment. It was founded by Roger Hansen, a Christian businessman who serves still today as Chairman of the Board of Directors. IRR, which was originally known as Gospel Truths Ministries, was established as a nonprofit, 501(c)(3) organization in 1986 and officially changed its n

ame in 1989. Throughout this entire period Luke worked alongside Joel Groat, who continued as IRR’s Director of Ministries. In September 2008, Rob Bowman, a veteran of nearly twenty-five years in apologetics ministry, joined IRR and served as its Executive Director, while Joel served as Director of Ministries. When Rob left IRR in 2018 for other ministry pursuits, Joel became Exec. Dir. When Joel resigned as IRR's Exec Dir in March of 2022 to assume the Exec Director position at Roosevelt Park Ministries, Rob returned to the Exec Dir position at IRR. We desire to promote — in a thoughtful and gracious manner — the exclusive claims of Jesus Christ as Savior and Lord, as revealed in the Bible. We are here to help you understand people of other faiths and lovingly share the grace of Jesus with them.

I've just posted the first in a series of articles that I hope to do on my blog addressing issues relating to Mormons and the Old Testament. (Mormons are studying through the Old Testament this year.) The first article deals specifically with Mormons and the Old Testament canon. Do they accept the same canon as Protestants (and Jews)? Well, yes and no. Link in the comments below.

Does the Book of Mormon really contradict the Bible? Yes, it does, despite the Mormon claim that the two are in happy agreement, as I explain in a new series of articles on IRR’s website. Two of these contradictions are at the heart of the Book of Mormon: its claim that material was removed from the Bible, and its story of Jesus coming down from heaven to visit people in the Americas. Other contradictions involve the fall of Adam and Eve, whether dark skin is a mark of God’s curse, salvation by grace, whether the Book of Mormon people observed the Law of Moses, and its references to Jesus as the Father and the Son. In the comments below, I give a link to the summary article from which you can find the articles discussing these issues in detail.

The first Tuesday in December has become known as “Giving Tuesday,” a day when special attention is focused on encouraging people to give to the charitable cause of their choice. If you are already supporting other worthy causes and IRR doesn’t fit into your charitable giving, that’s fine. Please give where and as you are led. I do want to let you know that IRR is in special need of funding due to two unexpected situations that arose at about the same time in October.

First, we had an extremely large number of orders, both unprecedented and unexpected, placed for IRR’s popular manual, Where Does It Say That?, which contains numerous photo-reproductions of documents showing what Joseph Smith, Brigham Young, and other LDS leaders actually taught. We quickly ran out and had to order it reprinted. (IRR is the only organization that publishes and distributes this resource.) In order to make the manuals affordable (and even give away many copies to Mormons), we have to get large numbers printed at one time, and we still depend on donations from our supporters to help underwrite the cost. In this instance, we ordered a thousand copies.

Second, regrettably, at about the same time as we incurred this sudden expense, donations to IRR took an unexplained drop. IRR operates on a low budget: our office space is donated to us, our office phone now is routed to my cell phone (!), and neither the office manager nor I can be paid a full-time salary. Still, we do have financial needs.

So, with some reluctance, I am making this appeal directly to those of you who follow this ministry page. Please consider making a special financial gift to IRR to help us cover our expenses and to continue ministering to people’s needs. You may do so via our website or by postal mail at IRR, 550 West Street, Cedar Springs, MI 49319. If you would like to receive our newsletters, which go out about six times a year and include a special teaching article, you may sign up free of charge on our website. I'll place some important links in the comments.

Thanks,
Rob Bowman

One of the most popular articles on the website of the Institute for Religious Research is entitled "28 Biblical Passages Which Explicitly Teach There is Only One God." I have recently edited, revised, and expanded this article. The article is an especially pointed rebuttal to Mormon theology, but it is also relevant to the Jehovah's Witnesses' doctrine. I will provide a link in the comments.

The following is a slightly edited version of the newsletter we just sent out prompted by two recent events.

On September 27, the president of The Church of Jesus Christ of Latter-day Saints, Russell M. Nelson (shown in the picture), passed away at the age of 101 years old. Nelson was the 17th LDS Church president and held that position beginning in early 2018. A distinguished medical doctor (holding both the M.D. and Ph.D. degrees), Nelson became the oldest LDS apostle as well as the oldest president of the LDS Church.

Christians ought to be forthright in their criticisms of Mormonism, including fair-minded criticisms of specific policies or claims made by Nelson, without engaging in character assassination or mean-spirited representations. Unfortunately, some people (whether Christians or not) on social media have posted unflattering memes portraying Nelson in a sinister manner or have made extremely harsh comments about him. Such responses to Nelson’s passing do not help anyone in the LDS Church recognize the errors of Mormonism or come to know Christ truly. It ought to be possible to express in a civil and gracious manner our reasons for viewing the LDS Church as a false religion.

The very next day, September 28, a man identified by authorities as Thomas Jacob Sanford drove a pickup truck into a church building of the LDS Church in Grand Blanc, Michigan—just two hours from our office—during their Sunday morning meeting. Reportedly, he shot people in the church, killing two persons, then set fire to the building, as a result of which at least two others were killed. According to our most current information, authorities say that Sanford was motivated by hatred for the LDS Church, apparently sparked by a bad relationship years earlier with a Mormon woman in Utah.

I want to make it absolutely crystal clear that what we do at IRR is motivated by love, not hate. Our critiques of Mormonism, the Jehovah’s Witness religion, and other modern religious movements that deviate from historic Christianity are driven by love for God, love for the people misled in these religious movements, and a firm commitment to the truth. Opposition to false religion is compatible with genuine compassion and concern for the people who are being misled. This does not mean speaking disrespectfully and harshly about people and then merely claiming to be motivated by love. It means showing genuine love for people by speaking in a civil tone, with gentleness especially toward rank-and-file members who may not know better or who (as is sometimes the case) were disillusioned by their past experiences in traditional Christian churches. It also means making the effort to understand these other religions fairly and accurately and to engage their claims with well-evidenced facts and a sound handling of biblical teaching.

The resources we make freely available on our website exemplify these standards. For example, the article “Love, Honesty, and the Defense of the Faith” begins with a list of 18 points from two chapters of the LDS curriculum manual Gospel Principles with which we fully agree. If you’re not familiar with this article, it explains in some detail what motivates us in our efforts to talk about matters of faith with members of the LDS religion (and with others as well). Another article in the same series on Gospel Principles and the Bible, “Mormonism and Jesus Christ,” sets out a list of twelve points about Jesus Christ on which Mormons and Christians are in agreement before summarizing ten LDS doctrines about Christ that are not biblically sound. I should also mention a newer article on the site, “How Do You Know That? Understanding and Responding to What Others Believe.” This article, which was originally a teaching article sent out with one of our newsletters, explains in some practical ways how to go about engaging what others believe in a responsible, fair-minded way. I will provide links to these three articles in the comments below.

Speaking of teaching articles, my most recent one is a short outline entitled “Developing a Constructively Critical Christian Mind.” This outline consists of several groups of bullet points on how to grow as a Christian thinker. You can get a copy of it by signing up for our newsletter free of charge. You may do so via our website, IRR.org, or by mail at IRR, 550 West Street, Cedar Springs, MI 49319.

Please pray for us at IRR to continue responding to false religions in a godly, compassionate manner, to speak the truth in love, so as to honor the real Jesus for his glory and for the blessing of those who need to know him.

I've told people that The Incarnate Christ and His Critics: A Biblical Defense, my 2024 book with Ed Komoszewski, is like getting three books in one: a defense of the deity of Christ, an argument for the historicity of the Jesus of the Gospels, and a study in comparative religions. Well, for a limited time now you can get three copies of the book for the price of two! Helpful for those who would like to have extra copies to lend out or give as gifts.

The central theological claim of Christianity, that Jesus is God incarnate, finds eager detractors across a wide spectrum--from scholars who interpret Jesus as a prophet, angel, or guru to adherents of progressive Christianity and non-Christian religions and philosophies. Yet thorough biblical...
