Searching For God at Boston College

Fr. Ronald K. Tacelli

Students at Boston College who learn solid proofs for the existence of God have an atheist professor to thank.

A little over 20 years ago, a history professor at the Jesuit college was advocating atheism in one of his classes. When Jesuit Father Ronald Tacelli, a professor of philosophy, learned of the class, he thought that if someone was not just conducting a survey course on atheism but was actually promoting atheism, he should do the same type of class for theism.

That’s just what he did, and with great results. Every year, Father Tacelli’s undergraduate philosophy course — “Does God Exist?” — attracts students who are unsure of or even hostile to the existence of a divine being. Prior to taking the course last fall, sophomore Matthew Johnson was skeptical, even “frustrated” with those who attempted to prove the existence of a divine being, saying he found those attempts “futile and wasteful at best.”

However, he saw the course itself as anything but futile because it improved his understanding of theism and gave him more respect for theists: “The class helped me to widen my views to incorporate proofs for God’s existence that were neither dogmatic nor far-fetched. I now consider myself, as Father Tacelli would say, ‘on the search.’ I don’t know if I believe that a God exists or not, but I was not even open to the idea of a God’s existence before Father Tacelli’s class.”

Michael D’Andrea had a similar experience. The sophomore business major said he was skeptical going into the course because of the “obvious bias” of the professor, but was pleasantly surprised with the amount of debate the course generated. He believes Father Tacelli went to appropriate lengths to include high-quality arguments from both religious advocates and atheists.

“What I can say now about the experience is that it was one of the most thought-provoking courses I have taken at Boston College,” he said. “I had been indifferent about the question of God’s existence before college, but became more and more interested after taking philosophy my freshman year. I decided to take the ‘Does God Exist?’ course because I was interested in the premise of the title and the debate proposed.”


D’Andrea shared the concern of many people regarding the simultaneous existence of both a divine being and an evil being.

“People today who do so much as open the newspaper can see the prevalence of evil and injustice,” he said, “so I had a very difficult time comprehending how a God all-powerful and all-good could allow such things to occur.”

He found the answer in human freedom, pointing out, “We must be free to do both good and evil for either to exist. Although they do not both need to exist in actuality for the other to exist, they must both be potential for the other to truly exist. If there’s not the possibility of doing evil, then there can’t really be good, because that would be automatic and not freely chosen. It wouldn’t be a genuine decision, but a compulsion. It would be forced, but that’s not what occurs.”

Force was not something that occurred in the classroom, either. Father Tacelli stated at the beginning of the semester that students were free to disagree with him, and he encouraged them to express their views, which would have no bearing on their grades. On the first day of class, students were asked to write down their personal beliefs regarding the existence of God. The class of 40 was then divided into small discussion groups based on the responses, with an emphasis on including varying opinions within each group.

Father Tacelli believes that concepts are learned better through the give-and-take of discussions, which were not emphasized in his first 10 years of conducting the class. He said he “used to do pure lecture for most of the class time, but discovered that wasn’t as effective as I wanted it to be, so I opened it up for more discussion. It is essential to have the various proofs for God’s existence explained, which I still do, of course, but now there’s more emphasis on the specific issues the individuals in the class are facing.”

Senior history major Christine Donahue appreciated the respect Father Tacelli had for individuals. She said the priest “would listen to students’ specific arguments and respond to them, instead of doing what teachers can sometimes do: They totally miss the whole point of the question and reply with an answer so far off topic that it leaves the student confused, and then he just smiles and nods. That’s not what Father Tacelli did at all. If a student had a good point, he would admit it; but if there were tons of holes in the argument, he would point them out and suggest ways they could be resolved.”

Donahue enjoyed such discussions and clarifications, because she was better able to understand belief in God.

“Being a Catholic myself, the class offered me a chance to learn personal, scientific and rational arguments that show the existence of God,” she said, “but it also challenged me to use that knowledge to defend what I believe about God and faith on my own during our small-group discussions with other students.”

‘Spiritual Pressure’

In addition to these discussions, Father Tacelli would meet one-on-one with each student on a regular basis.

“It’s wonderful to see the true depth of young people, who are often looked upon as ‘shallow kids,’” he said. “It’s a blessing to witness them coming to terms with the deepest questions a person can ask, and it fills me with a tremendous respect for their personal and spiritual struggles.”

This is a different experience from the other philosophy courses he teaches.

“With my other classes, there’s a purely academic pressure to conduct the class well, but with this class specifically, there’s an added spiritual pressure,” he said. “I feel these students have been given to me by God to look after, and I have a responsibility to present them with compelling arguments. I’m not the sharpest knife in the drawer, but, then again, I’m not the dullest one either, so I definitely feel that responsibility to communicate accurate information on this most important question. If there’s a problem in communication, then it’s with me and not with the evidence.”

Much of that evidence has been complied by Father Tacelli and his Boston College colleague Peter Kreeft in Handbook of Catholic Apologetics (Ignatius, 2009). This book is a main source for the arguments used in the class and is supplemented with other sources, such as God Matters and God Still Matters, both by Dominican Father Herbert McCabe. Not one to confine the study to one semester, Father Tacelli ends the course by giving individual students books he thinks would be particularly useful to them on their journeys. “The study doesn’t end with the last day of class; it’s something that lasts throughout life, so I like to leave the students with more to think about.”

Matthew Johnson has continued thinking about God, in part by reading books from Father Tacelli, including Progress and Religion by Christopher Dawson and Mere Christianity by C.S. Lewis. Johnson says that “Father Tacelli has been an excellent advisor, guide and mentor on this journey, and though he has certain beliefs and articulates and advocates them strongly, I never felt judged or looked down upon because I wasn’t ‘a believer.’ In fact, what he teaches and how he teaches it have opened up the possibility of me becoming ‘a believer.”

Many students have had their anti-religious assumptions checked, and unsure theists have had their beliefs strengthened. But have there been any theists who become atheists after the course? Father Tacelli let out a hearty laugh at the question.

“I hope not,” he said, “but maybe I didn’t present the case too well in specific instances. However, the overwhelming majority of students leave the class with a renewed respect for religious beliefs and a renewed understanding of them.”

He concludes: “In one sense, we do have that atheist professor to thank for providing the motivation for my teaching the ‘Does God Exist?’ class. Without him, I may never have come up with the idea.”

    Good for Fr. Tacelli. He should package it and send it to the other Jesuit universities.They could use it. Writing as a retired scientist (PhD Chemistry) I am astounded that any scientist would be an atheist. Look at the processes in any human cell and tell me they are the result of a sequence of random undirected events. “C’mon man!” Read “The Mind of God” by Paul Davies then tell me the universe just spontaneously popped into existence or that it always existed. “C’mon man!” Ironically there is no real conflict between religion and science as some maintain. The more we learn in science, the more it supports the existence of the God of Scripture.

    Three cheers for Fr. Tacelli and Dr. Poppriexno’s comment. I always had the same thought, how can anyone be a true scientist and an unbeliever? Please. Science only affirms religion.

    My daughter attends a prominent university in South Carolina (think TIGERS) and can bear witness to things being said by the Catholic Campus Minister (a layperson) that directly oppose Church doctrine. We are fortunate that each time she has been exposed to untruths, she has come to us (we live within an hour of campus) to discuss what she experienced. We have kept our dialogue about our Catholic faith very out in the open with our daughter, and she is a better Catholic for it. Thank you Fr. Tacelli for helping to “raise them up” in the way that they should go! AMEN!

    Many students who meet the academic admission requirements eagerly seek admission to BC. Many who are Catholic, or Christian, who seek the opportunity to study at a Catholic College…but yet are turned away in favor of atheists or those who have no religious considerations either way…and why is that? If BC required a statement of Catholic Faith on admission decision, as well as Pastoral letters, as several Christian Colleges do,maybe BC wouldnt need Father’s course. Shameful.

    I went to a Catholic college where many of the students applied as
    “Catholic,” mostly to increase their chances of being admitted, or
    simply because they were raised Catholic. Many, I would even guess, the
    majority, did not practice. In fact, most complained it had been a
    mistake to claim Catholic on the app, since then they were obligated to
    take the course bib theo as a general requirement!
    Even for those who
    did practice, though, I think college is a common period of
    philosophical change, doubts, and exploration. I think it’s great there
    is this class to help those who struggle with their faith during these
    years. Even for those more solid in their faith, a class such as this
    will help them be more confident when in a discussion with those who
    believe differently. While I believe in God, I find it a huge challenge
    to explain when debating an atheist. It can be a great discussion in
    the end though when you can intelligently offer them some logical
    philosophy to ponder.
    Just my two cents. 🙂
