Discussions on teaching and learning within theological seminaries often center on the question of student diversity, focused primarily upon issues of race, gender, and ethnicity. At the same time that seminaries are challenged to deal with a multitude of pedagogical suppositions emerging from increasingly diverse learning goals, seminaries must also pay attention to the ways their students challenge an institution's core mission to train ministers for service in churches and denominations. Based upon the author's experience teaching in a mainline Protestant seminary, the essay discusses three student cultures that often overlap among today's seminarians. These three student cultures, referred to here as "church seminarian," "new paradigm seminarian," and "vocational seminarian," carry very different understandings of the seminary's role to prepare students for ministry. A critical discernment of these cultures might challenge seminary faculty to reevaluate their educational and missional suppositions amidst divergent student career objectives.
