SBLThis citation style is the one preferred by the School of Theology and Seattle Pacific Seminary. Its default is (1) notes and bibliography (6.1-4, pp. 68-104), but it offers also (2) an author-date and works cited option for "Authors writing in [practical theology and] the social sciences" (6.5, pp. 104-108). It is based on Chicago style. SBL stands for the Society of Biblical Literature.
