A recent article on 1 Tim 3:15:

Stefan Krauter, “Die Kirche—Pfeiler und Fundament der Wahrheit? Zur Übersetzung und Auslegung von I Tim 3,15f.” Theologische Zeitschrift 77.1 (2021): 45–59.

The article is in German, but an English-language abstract is provided: “I Tim 3:14–16 is considered the theological centre of the Pastoral Epistles. The text combines the Pauline image of the church as a temple with the image of the church as house of God, which is characteristic of the Pastoral Epistles. In this way, the church is portrayed as a firm institution that passes on the truth unadulterated. The paper questions this interpretation in three steps: lt examines whether there is [a] temple metaphor in the background of l Tim 3:15. The idea that an institution carries the truth of faith is examined. An alternative translation and interpretation of the passage is proposed.”
