Acton University: Ecumenism 101 with Peter Kreeft
Acton University: Ecumenism 101 with Peter Kreeft
Feb 27, 2026 12:56 AM

This summer, the interns at the Acton Institute have bonded over campfires, swing dancing and piles of folders and name tags. About half of the 18 interns are Catholic, and the others subscribe to a variety of Protestant denominations. Although most of us are studying economics, we each care deeply about our faith. As the evenings progress, our conversations often turn to topics of religion and theology.

Acton University attracts participants from a variety of denominations and religions around the world. This year, Peter Kreeft, a highly regarded professor of philosophy at Boston College, gave a presentation titled “What Catholics and Protestants Have in Common.” Kreeft is a convert from the Dutch Reformed Church to Catholicism, who is passionate about how Catholics and Protestants relate to one another. He ended his lecture with four practical rules for anyone in an ecumenical setting.

“Don’t idolize anything (even reunion).” Sometimes people value the idea of unity so much that they are willing to sacrifice truth to achieve some level of agreement. As the interns discuss tricky theological questions, we are sometimes frustrated that we e to a resolution to our heated discussions. We need to remember that, while unity is important, our goal should be to grow closer to God. If we truly grow closer to Him, we will grow closer to each other. This process will be the result of God’s unity and truth, not our own efforts.“Begin with what we have mon.” Kreeft devoted a good deal of his lecture to reminding us of all the things Christians share. His goal was not to dismiss or minimize differences, but to remind us of some of the things that matter most. For the interns, we began a few weeks ago with a shared love for God, for truth, for the free market, for adventure and for cinnamon rolls (which is no small starting point).“Listen. Sincerely, open-mindedly, honestly.” One of the best ways to do this is to ask a question to which you honestly don’t know the answer. Among the interns at Acton, minds often jump from one idea to the next as we draw connections parisons; very soon we are interrupting the answer to our original question. Patiently listening and waiting for each other to speak can make the difference between multiple people giving monologues and a productive dialogue between equals.“Listen to God. Pray to conform your will to His.” This last rule is what truly unifies the church. Some interns cross themselves when they pray while others do not. Some prefer beautiful memorized prayers that have stood the test of time, while others prefer impromptu, heartfelt adoration. Still, we have joined together in prayer before meals and Bible Study, going to the same God for wisdom, truth and grace.

These same ideas can be applied when Christians discuss politics. Thoughtful believers can disagree on important issues, and sometimes these debates can get more heated than religious discussions. Remembering these principles when discussing ideas such as socialism, fair trade and public unions helps us treat each other with respect.

radery we feel is not the result of a relativistic belief that each opinion is as right as the next. After all, Kreeft joined the Catholic Church because he believes it speaks truth in areas where the Dutch Reformed Church does not. Instead of clinging to the false unity of relativism, the interns understand that we each have some access to the objective truth found in God. Although each of us tends to believe that we are the one with the clearer and more accurate picture, we must choose to humbly seek the truth. This side of heaven, we can’t perfectly identify where we’ve erred or prehend what is merely a glimmer of the true Light. By focusing on the truth and making an effort to really listen, practicing intellectual humility and seeking God, we can meaningfully engage with one another.

C. S. Lewis speaks about denominational differences in Mere Christianity. pares the truths all Christians share to a great hall and the various denominations within Christianity to rooms in a house. “When you have reached your own room, be kind to those who have chosen different doors and to those who are still in the hall. If they are wrong they need your prayers all the more; and if they are your enemies, then you are under orders to pray for them. That is one of the mon to the whole house.” At Acton University, people from over 80 countries had the opportunity for “hallway” encounters with believers of different faith traditions. As we return to our rooms after the conference, we ought to continue to lift each other up in prayer as we seek truth about God and society.

Efficiently combating poverty
This essay won firstplace in the essay contest of the Acton Institute’s 2020 Poverty Cure Summit, which took place on Nov. 18-19, 2020. This essay is presented as it was submitted. – Ed. Eradicating poverty, or at least effectively reducing it, is one of the oldest and most debated issues in the field of economics. Several solutions have already been presented and yet the problem persists in many places. The specificity of each region of the globe makes it even...
John Paul II on work, socialism, and liberalism
This year marks the 30th anniversary of John Paul II’s important encyclical, Centesimus Annus. While the average lay person might not pay attention to formal pronouncements by the Roman Catholic Church, papal encyclicals are significant in their affirmation of the church’s social doctrine. Of course, Protestants have no such magisterium to which they might appeal, and it goes without saying that there exists no such thing as “Protestant social teaching.” Given the importance of the Christian church’s unity and its...
Tim Scott’s response to Joe Biden’s address to Congress: 6 quotes
Sen. Tim Scott of South Carolina delivered the Republican response to President Joe Biden’s address to a joint session of Congress.

The 3 things you need to make ‘socialism’ work
Occasionally, our antagonists think they have discovered the silver bullet argument in favor of “Christian socialism.” One such apology recently came into my inbox. In its entirety, it read: Acts Chapters 4 and 5 Tell of The Holy Spirits Work with The Apostles to Establish SOCIALISM for The Christian Church…What further proof is needed ??? Recourse to the exceptional model of charity practiced by the early munity in Acts 4:31-35 is as perpetual as it is erroneous. As I’ve noted...
Bishops: The Equality Act will destroy Christians’ careers
The bishops of the world’s oldest Christian church have condemned the proposed “Equality Act” – not just based on its threat to religious liberty – but also the danger it poses to Christians’ ability to make a living. The “Equality Act” could bar faithful Christians from serving their fellow citizens and improving the lives of people from all sexual orientations. The foundations of the Eastern Orthodox Church stretch back to apostolic times. In this country, the jurisdictions coordinate their work...
‘More Work, Fewer Babies’: The future of family in an age of ‘workism’
Birth rates are in free fall across the Western world, spurred along by plex web of factors, from increases in economic prosperity and egalitarianism to declines in religiosity to idols of choice and convenience. Whatever the reasons, family has taken a back seat in the hearts and minds of many. “Most of today’s Americans believe that educational and economic plishments are extremely important milestones of adulthood,” according to a recent study by the U.S. Census Bureau. “In contrast, marriage and...
A silver lining in the Golden State’s school shutdowns
What happens in California doesn’t tend to stay in California – and that’s usually bad for America. For instance, “55% of all public school students, including those in charter schools, were at home, in distance learning, as of April 30, according to an EdSource analysis of new data released by the state.” However, a new and growing parental rights movement in the state is making headlines, creating change, and forging a national push for the nation’s still-shuttered schools to reopen...
Goodbye to the Acton Institute
As a member of the clergy with multiple secular jobs, things are always hectic. I’ve decided I must step away from my work with the Acton Institute beginning the first week of May and, I’m sad to say, this marks my final new blog for the Acton Institute. (A few more entries will appear next week, as will some articles for the Spring 2021 issue of Religion & Liberty analyzing the first days of the Biden-Harris administration but – spoiler...
Sen. Tim Scott’s message of redemption resonates
Our weakened state, due to original sin, does not mean that we are wicked, evil, or insignificant. It means that we have a wound—a particular kind of wound that demands a particular kind of medicine.

Biden’s ‘stimulus’ for a growing economy is all about central control
President Biden wants to pump nearly $2 trillion more into the U.S. economy under the guise of “economic stimulus.” But the country’s economy has already been growing for months, proving that American politicians have adopted the term “stimulus” for a new regime of spending programs that drive up debt needlessly, taking a page out of Xi Jinping playbook.
