Benjamin Warfield delivered an address at Princeton Theological Seminary in 1911 on the topic, ‘The Religious Life of Theological Students’. An abridged from of this was published in the Western Reformed Seminary Journal (8/2, 2001, 23-27). Yes, an already short document was reduced to just a few pages. I’ve made a few extra changes, added a few subheadings, and formatted it so it prints out nicely as a little booklet (with happy permission of the WRS Journal editor). Here it is in Word and PDF.
