Unless, the author says, you are independently wealthy, have sure job afterwards (and that is a sure job, not just a good shot at a job), have a spouse who already has a steady source of income, or you are earning a credential for a position you already hold.
Though the advice given here may be a hard pill to swallow for students looking to go on for a PhD of some sort (including in theology, biblical studies, or religious studies), it is worth hearing. The competition for jobs is fierce. For example, I was on a search committee a couple years ago for a College post, and we had over 30 applicants, the majority of whom not only had PhD’s, but also had some teaching experience. And this for a job in the middle of Saskatchewan–not exactly a place where people are pining to move!
Of course, this isn’t to say that you shouldn’t consider a humanities or theological studies PhD, but if you are going for one, you may need to consider, up front, that you may need to think very creatively and laterally about where and how you plan to use that degree once you are done. Only a small minority get into university, college or seminary positions. If that is your primary objective–well, don’t count on it.
I don’t want to discourage anyone here, and I think the Church actually needs a lot more people with humanities and theological studies PhD’s willing to serve in ministries and vocations outside of the academy. But I would be irresponsible if I didn’t tell prospective grad students to consider the realities to which this author points.
