Monday and tuesday were spent in and around Leiden. Leiden is a famous university city, and as such there are a lot of young people walking and biking in it, raising the general energy level accordingly. These first days were given me to enable me to acclimatize to an as yet new environment. I quite enjoyed Leiden, a city that dates back to the 9th century AD. Living in Canada, it is difficult for us to comprehend the age of many European cities. What would it be like to live in a place where countless generations of one's ancestors had lived before oneself? Here are some photographs of Leiden:

Nederland 2026, 2: Arrival and Oud-Poelgeest
My journey began with an overnight flight from Toronto's Pearson Airport to Amsterdam's Schiphol Airport. The flight was about an hour late in leaving and took approximately seven hours in total. Having cleared customs, which takes some time for travellers with non-EU passports, I was greeted by my great friend Samuel Vandeputte, whom I was delighted to see again. As I wrote in my last post, we saw each other regularly during his studies in Canada. After he returned to the Netherlands and then entered graduate studies at Leuven, Belgium, we kept up with each other via regular online conversations. He now works in the field of journalism.
We deliberately kept monday and tuesday fairly free of commitments to allow me to adjust to the UTC +2 time zone covering western Europe. My first days were spent at the Hotel Landgoed Oud-Poelgeest in Oegstgeest, a village north of the city of Leiden. The hotel sits on a beautifully wooded property on which stands a kasteel, or castle. No, not a mediaeval castle, but a stately mansion in which lived the famed Dutch botanist and polymath Herman Boerhaave (1668–1738). During my stay there, I would walk around the property every morning after breakfast, enjoying the footpaths, water channels, and diverse flora, much of which is unfamiliar in North America. However, Boerhaave planted a famous tulip poplar that lived into the mid-20th century. Only shoots survive into the 21st. This tree is definitely familiar to me because we have one in our front garden. Many locals walk or run through this lovely property on a daily basis.

A broken communion
Christian Courier just posted my monthly column, titled, A broken communion. What about? "At Synod 2026, the CRC decided to withdraw from the World Communion of Reformed Churches. Was this the right choice?"
I do not normally weigh in on ecclesiastical issues in this space, but given my long association with and current membership in the Christian Reformed Church (CRC), I think it is appropriate to comment on Synod 2026’s decision to withdraw from the World Communion of Reformed Churches (WCRC). I understand that church denominations have to weigh their associations carefully to ensure that they align with their mission and identity. But I believe Synod was too hasty in ending our relationship with this global communion, and I hope it isn’t too late to correct this.

The hubris of dominion theology: Bruce Barron
Last year Bruce Barron reviewed my most recent book on his Substack under this title: Should churches endorse political candidates? Two weeks ago Barron published a new post, The hubris of dominion theology, in which he published my own comments on an earlier draft of the post. An excerpt from my comments:
I don’t think the faith of our political leaders is altogether irrelevant to doing justice in their respective offices. This is the grain of truth in Christian nationalism and similar movements. However, this is dependent on such Christians cultivating and retaining an awareness of how the several political ideologies work to distort their perceptions of reality. Adding Christian to nationalism, or to any other ideology, in no way guarantees that it will produce just governance. Sad to say, even otherwise orthodox believers are susceptible to the allure of the ideological visions (or illusions) on offer in the public realm.

Belonging to God: manuscript submitted
The earliest material in the book dates to around 2009 when I wrote a series of commentaries on the Ten Commandments for the benefit of my students. In 2016 I decided to write a fuller exploration of the Heidelberg Catechism, incorporating much of this material, although I was not yet clear as to its purpose. I completed this during the summer of that year. The following year I was caught up in the events surrounding the loss of my teaching position and efforts to find something new. In the short term this led to a revision of my first book, Political Visions and Illusions, which came out in a second edition in 2019. This was followed by translations in Portuguese and Spanish. By then I was affiliated with Global Scholars Canada, an association I have found extremely fruitful for advancing my work. Then came Citizenship Without Illusions, something of a sequel to my first book, applying its principles to the practice of citizenship.

The 'Deep State'?
Those who speak of a deep state suspect that there is a vast network of persons working clandestinely within the institutions of government to derail the intentions of elected officials. Their goals are hidden from public scrutiny; their nefarious activities dressed in the garb of public service. If any official threatens to expose them, they will ensure that he or she is thwarted or removed from office.
What do we make of this "deep state"? Read more here for my take on the matter.

Evangelical 360 interview
In January of this year Brian Stiller interviewed me in studio at the offices of the Evangelical Fellowship of Canada (EFC) in Scarborough, Ontario. Brian is a longtime leader of the evangelical movement in this country, having served as the president of the EFC and of Tyndale College and Seminary. He is now a Global Ambassador of the World Evangelical Alliance. Our interview has now been posted and can be accessed below.

UpNext interview: 'Faithful Citizenship'
Back in January (note my winter beard length) I was interviewed by Tommy Lee, founder and president of Resource Global, for his UpNext Podcast on the subject of my most recent book, Citizenship Without Illusions. We had a good conversation that covered a lot of ground, including two treasured mentoring relationships and my sideline in music and psalm versification. The interview has now been posted and runs for a little over half an hour.
Here is the description from the YouTube page:
Politics can feel exhausting, divisive, and overwhelming. As Christians, should we engage, or step away entirely? In this episode of UpNext, Tommy Lee sits down with political scholar and author David Koyzis to explore what faithful citizenship looks like in today's polarized world. Drawing from his book Citizenship Without Illusions, David shares why political ideologies often become idols, how Christians can engage politics without becoming cynical, and why lasting change often begins in our local communities. Whether you're passionate about politics or prefer to avoid it altogether, this conversation offers a biblical perspective on navigating disagreement, serving your neighbors, and keeping your ultimate allegiance to the Kingdom of God.

Political Faithfulness in a Polarized Age
In his book Political Visions & Illusions, David Koyzis argues that the dominant political ideologies of our day—from socialism to nationalism—are undergirded by idolatry. By idolizing the individual, the past, the future, or the collective, we transfer our love to false gods. This idolatry fuels identity politics, public discourse that is less about the common good and more about individual performance.

Our ancestors hated each other
This year marks Nancy’s and my 30th wedding anniversary. On our honeymoon, we travelled through the mid-Atlantic states, visiting sites associated with our respective family histories. In April and May of this year, we returned to some of these places, especially Baltimore, Annapolis, and St. Mary’s City, the first capital of Maryland in the seventeenth century.

An extraordinary Hollander
Christian Courier has published my latest: An extraordinary Hollander. The subject? A man who served as mentor for Abraham Kuyper. An excerpt:
This year marks the 150th anniversary of the death of one of the great figures in Dutch – and arguably Western – history. Guillaume Groen van Prinsterer was born in 1801 and was raised in a Netherlands undergoing significant change. When revolution broke out in France in 1789, it would unleash such instability as to plunge Europe into a full generation of war and bloodshed.
Much as Edmund Burke, whom we visited last month, foresaw the Revolution’s trajectory, it fell to Groen to assess it in retrospect. With the advantage of hindsight and under the influence of the Réveil, a Christian revival then sweeping Protestant Europe, Groen was persuaded that the Revolution was rooted in a rejection of God and in misplaced faith in political ideologies and their false promises of earthly salvation.

Théologien? Moi?
David Koyzis is a unique figure. This Canadian is relatively unknown in the Christian world and receives very little media attention; he doesn't even have a Wikipedia page. He holds a doctorate in political science and adheres to Reformed orthodoxy, which theologically aligns him with evangelicals committed to the Holy Scriptures.

Reckoning with Christian Nationalism, 2
I appreciate Wood’s emphasis on “serious engagement with [Christian Nationalism] before critique.” Indeed we need to discern what is right about someone’s position before we can level a credible critique. I would go further than Wood on this score. There is something right about communal solidarity, full stop. Whether that community is the state, the nation, the family, the workplace community, or something else, we rightly celebrate the bonds that hold people together as they live their lives and pursue their daily vocations. There is in principle much good in the fact that Americans and Canadians love their respective countries and take pride in their achievements.

Burke's continuing relevance
In 1790, one year after revolution had broken out across the channel, the Anglo-Irish statesman Edmund Burke wrote his now classic Reflections on the Revolution in France. Many of Burke’s compatriots, especially his fellow Whigs, thought that the French were finally rid of their absolutist government and were embracing the constitutional institutions which they themselves had long enjoyed. They thus gave qualified support to the revolution.
Burke would have none of this, sensing that something more destructive was afoot in that country. The revolutionaries were going much further than to replace flawed rulers with better ones. In fact, their efforts would soon lead to a reign of terror, something that Burke foresaw in his Reflections.
Read the rest of the column here. I have now been writing for Christian Courier for 36 years. Next month's column will cover Guillaume Groen van Prinsterer, an intellectual and spiritual heir of Burke whose recent biography by Roel Kuiper I have reviewed here.

New book contract: 'Belonging to God'
I am pleased to report that I have just signed a contract for my next book, an in-depth exposition of the Heidelberg Catechism with a focus on its implications for our life in God’s world, especially public life. Although the timeline is admittedly short, the manuscript is basically complete and simply needs to be formatted to conform to the publisher's specifications. This will occupy my time for the next little while.
I see this new book as foundational for my other three published volumes, as it elucidates the faith that underpins them. If the books are to be read in logical order, proceeding from faith basics to application, one would begin with "Belonging to God," then proceed to We Answer to Another: Authority, Office, and the Image of God, then Political Visions and Illusions, and finally Citizenship Without Illusions. I will keep readers informed of the progress of this new project as it moves towards publication.

More on the 'Neo-Calvinist rodeo': two cheers for the market
We talked about our common ground of Scripture and catholicity. We debated the proper relation between the Law and the Gospel. We discussed the fraught history of traditionally Orthodox societies with autocracy, while nevertheless noting many important—and too often overlooked—exceptions. To that end Koyzis even expressed his hope that my book would be translated into Greek, Russian, and other traditionally Orthodox languages.
