To which sacred writings was Paul referring to in 2 Timothy 3:14-17? This article suggests that they were more than the Old Testament; the author advances the thesis that Paul was talking about New Testament writings as well.
The appearance of the Greek word "eusebeia" (godliness) is very frequent in the Pastoral Letters (e.g., 1 Timothy 4:6-10, 1 Timothy 6, 2 Timothy 3). Some theologians interpret this frequent occurrence as a shift in New Testament ethical thinking. This alleged shift occurred because the second coming of Christ did not appear so imminent as was earlier expected.
