Ten hours of discussion of the actual text wasn't enough for us, so Ryan Hurd and I are inviting some guests to come talk with us about the trinitarian theology of Amandus Polanus. This week we asked Dr. Tyler Wittman…

Polanus, Axioms 17 and 18 On the Trinity

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…

Aquinas on Procession

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…

Polanus, Axioms 15 and 16 On the Trinity

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…

Polanus, Axiom 14.6 On the Trinity

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…

Polanus, Axiom 14.5 On the Trinity

Perichoresis! So hot right now. Actually, so hot all the time. The confession that the persons of the Trinity mutually indwell each other --"I am in the Father and the Father is in me"-- is directly evident from Scripture, has…

Polanus, Axiom 14.4 On the Trinity

One of the things you can say about the divine persons is that they are equal with each other. Right between affirming their consubstantiality and their mutual indwelling, Polanus devotes a couple of paragraphs to affirming their equality. "The three…
