What I Learned From Polycarp About Pearls, Swine, And Modern Evangelicals

Why Do Good Men Approve Of Bad Texts?

Reformation Day 2022: The Antidote For A Fearful People

On reflection, it is rather amazing that an obscure Augustinian monk from a German backwater, teaching in an obscure school, was able to turn the Holy Roman Empire on its ear. Just as amazing is the fact that the greatest known powers . . . Continue reading →

Speaking In Foreign Languages In The Church? The Adoption Of Business Language In The Church In Light Of 1 Corinthians 14:27

What then, brothers? When you come together, each one has a psalm, a lesson, a revelation, a foreign language, or an interpretation. Let all things be done for building up. If any speak in a foreign language, let there be only two . . . Continue reading →

Lamenting Christendom

What difference should the visible church make in the broader culture? How significant should it be? How one answers this question tells us something about how one views the relations between Christ and culture and the evident death of Christendom. Defining Christendom . . . Continue reading →

Found: One Lost Category

To follow up on the earlier essay on Christ and culture, I want to make a further observation about the importance of creation or nature as a category of thought. When many conservative Christians think of creation, the first thing they think . . . Continue reading →

The Crisis Of The Hour: Christ And Culture

There may be no more pressing issue before Christians (as individuals) and the visible church (as a corporate body) than the question of Christ and culture. Much of what concerns us all just now goes back, in one way or another, to . . . Continue reading →

A Word About R2K

Since David VanDrunen published, in 2010, the first volume in what has become a series of important volumes, Natural Law and the Two Kingdoms: A Study in the Development of Reformed Social Thought, Emory University Studies in Law and Religion (Grand Rapids: Eerdmans, 2010), there has been a certain degree of controversy in some quarters of the confessional Reformed world over the recovery of the “two kingdoms” as a way of thinking about Christ and culture and ethics.

Stemming Another Rising Tide Of Theonomy: Hebrews 7:11–14 (2)

Now if perfection had been attainable through the Levitical priesthood (for under it the people received the law), what further need would there have been for another priest to arise after the order of Melchizedek, rather than one named after the order . . . Continue reading →

Stemming Another Rising Tide Of Theonomy: Hebrews 7:11–14 (1): Background

When the theonomy movement initially began to gain steam, Jimmy Carter, a Southern Baptist who had campaigned as a “born again” Christian, was part way through his first and only term in the White House. Three years before that, the Supreme Court . . . Continue reading →

The Commander Of Yahweh’s Army: The Son And The Covenant Of Grace Present In The Types And Shadows

When Joshua was by Jericho, he lifted up his eyes and looked, and behold, a man was standing before him with his drawn sword in his hand. And Joshua went to him and said to him, “Are you for us, or for our adversaries?” And he said, “No; but I am the commander of the army of the LORD. Now I have come.” And Joshua fell on his face to the earth and worshiped and said to him, “What does my lord say to his servant?” And the commander of the LORD‘S army said to Joshua, “Take off your sandals from your feet, for the place where you are standing is holy.” And Joshua did so (Joshua 5:13–15; ESV).

1689 Vs. The Westminster Confession (9): Of Free Will

Our comparison and contrast of the WCF with the 2LC continues through chapter 9, “Of Free Will.” A word of explanation about this language is in order. In 2022, when we hear or read the phrase “free will,” we might be tempted to . . . Continue reading →

Paul’s Golgothic Doctrine of Sanctification

Was there a more un-sanctified and immature congregation of which we have an apostolic record than the Corinthian congregation? From a reading of Paul’s two canonical letters to them they were beset by power struggles and schisms within, tolerant of gross immorality, . . . Continue reading →

Stop Saying That Amillennialism Is “Pessimistic” But Postmillennialism Is “Optimistic”

This is a classic case of begging the question, i.e., assuming what has to be proved. People regularly say that amillennialism is “pessimistic” but postmillennialism is “optimistic.” Who is pessimistic about what? Define pessimism. Who says? By what standard? I say that amillennialism . . . Continue reading →

The Lapsed Now And Then: What The Decian Persecution Teaches Us About Recovering From Covid

The Roman soldier handled Perpetua roughly. There was no question who was in charge. He took her before the Captain to be questioned and then to the Procurator. The procedure was simple. He asked her one question three times: “Are you a . . . Continue reading →
