Acton University: Ecumenism 101 with Peter Kreeft
Acton University: Ecumenism 101 with Peter Kreeft
Apr 9, 2026 2:17 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.

Religious Shareholder Activists: Enemies of Debate
From the time your writer opted to publicly proclaim his policy opinions in a variety of forums that are privately funded, he has incurred estrangement from ideologically opposed friends and family members, as well as receiving threatening emails and even frightening phone calls plete strangers. From the above experiences, it was easy to glean progressives can be very nasty (comments I receive often remark negatively on my choice of eyewear). Most tellingly, however, presume to know the private funding sources...

Lessons of the Flint Water Crisis
“As all the media attention attests, the sad story of Flint is not limited to itself,” says Kishore Jayabalan in this week’s Acton Commentary. “The entitlement mentality is like a drug ruining not just American cities but spreading to the country as a whole.

The 7 Best Super Bowl Commercials About Vocation and Stewardship
Contrary to the trite assertion made every year by people who don’t know how to appreciate football, it is not really true that mercials the best thing about the Super Bowl (at least not always). Sure, it may seem that way because the television viewer is mercials than actual game play (in an average game, theratio mercials to playing time is seven to one). The reality, though, is that most of mercials aren’t all that memorable. Only a few stand...
No, Jesus was not a socialist
The resurgence of socialism in America, especially among the young, seems to be based on a widespread form of wishful thinking and historical ignorance. Most people who support Bernie Sanders, for instance, do not realize that most of his ideas have been tried already—and discarded as unworkable. Similarly, many Christians who support Sanders don’t realize that for centuries socialism has been considered patible with Christianity.Since the mid-1800s every Catholic pontiff—from Pius IX to Benedict XVI—has forthrightly condemned socialism. Protestants don’t...
Property Rights Vital for Empowering the Poor
On Jan. 27, Acton’s Rome office sponsored a presentation of The International Property Rights Index at the Dominican-run Pontifical University of St. Thomas Aquinas. The private seminar was a premier event in Rome for the index’s publisher, introducing data and case studies sampled from 129 industrialized and developing nations. It was attended by some 40 leveraged opinion makers from the ranks of legal, political, academic and religious sectors. Speakers included the university’s dean of social sciences, Fr. Alejandro Crosthwaite, who...
Does capitalism reduce violence?
It’s been said before, but it’s certainly worth saying again. Not only does the free market lead to material wealth, but it reduces violence. On a recent episode of the podcast “Question of the Day,” co-host Stephen Dubner reads a question from a listener: Why haven’t humans evolved as a species away from aggression? Dubner and James Altucher deal with the question in a rather roundabout way. Altucher points out that, really, aggression has dropped for as long as we’ve...
Young Socialist Hearts, Old Conservative Heads, and Correctly Attributed Quotes
In the recent Iowa Caucus, young Democratsfavored the socialist Bernie Sanders by a margin of six to one, while older voters went overwhelmingly for the more traditionally progressive Hillary Clinton. The support of an old socialist by young voters and socialism should remind us of that old quote . . . you know the one, the one by . . . Churchill? When es to citing famous quotations, a good rule of thumb is to attribute any unknown saying either...
Plans to Prosper? The Forgotten Truth of Jeremiah 29
For many evangelicals, 2 Chronicles 7:14 has e a predictable refrain for run-of-the-mill civil religion, supposedly offering thepromise of national blessing in exchange for political purity. “If my people, who are called by my name, will humble themselves and pray and seek my face and turn from their wicked ways, then I will hear from heaven, and I will forgive their sin and will heal their land.” If the nation returns to golden days of godliness, we are told, blessings...
Unemployment as Economic-Spiritual Indicator — January 2016 Report
Series Note: Jobs are one of the most important aspects of a morally functioning economy. They help us serve the needs of our neighbors and lead to human flourishing both for the individual and munities. Conversely, not having a job can adversely affect spiritual and psychological well-being of individuals and families. Because unemployment is a spiritual problem, Christians in America need to understand and be aware of the monthly data on employment. Each month highlight the latest numbers we need...
