Just a quick note here on the blog, to hold a link to a helpful sermon from Richard Chenevix Trench, “On the Duty of Hating Vain Thoughts.” It’s from an 1886 collection of sermons freely available at various places online, but I excerpted the sermon

I almost missed this, because I wasn’t reading very closely in what I considered a mere devotional book by a forgotten author. I admit I don’t expect to be smacked with new insights from devotional reading. A few years ago I picked up a copy

We recently finished our series of conversations on seventeenth-century theologian Amandus Polanus’ 18 Axioms on the Trinity. Now Ryan Hurd and I are going to have a few conversations with people who know a thing or two about Polanus, Protestant Scholasticism, trinitarian theology, and related

The three persons of the Trinity coexist eternally, but not in the same way that other things coexist, mainly because these three are infinite, and not external to each other. And one of the Trinity, the eternal Son, took human nature into union with himself

Thomas Aquinas’ treatise on the Trinity in the first part of his Summa Theologiae runs from question 27 to 43. It’s a vast discussion, all but comprehensive in its coverage of the most important elements of Trinitarian theology. So sweeping an account could start from

When speaking of the Trinity, you can say three, but you can’t say triple or threefold or triplex. And you certainly shouldn’t say that the Father, Son, and Holy Spirit are three beings. In these two axioms, Polanus is largely covering ground he has already

I like this compact account of Trinitarian terminology in Vladimir Lossky’s Dogmatic Theology, 38-40. It’s especially good at showing the relation between the words ousia and hypostasis. Watch how Lossky relates the key terms to each other and uses them to draw out how they

In trinitarian theology, the word “mission” is a precise and technical term. Though the word itself just means “sending,” a trinitarian mission is the external personal operation of one of the Trinity. It presupposes something very important, and that is an eternal relation of origin

I think it’s fair to say this will not be one of the easier episodes, because Polanus lays out quite a bit of difficult material here, and it’s all interconnected. We are nearly done with the very long Axiom 14. This sub-section of the axiom

Tropos hyparxeos! Polanus comes to the point where he is ready to teach about the distinction of the persons from each other, and he invokes Cyril and Aquinas as authorities in affirming that the distinction among the persons ought to be the smallest of distinctions.
