Beginning next year, 2023, Horizons and Theological Studies will follow the same journal style in dealing with matters related to citation, punctuation, spelling, and so forth. In collaboration, the editors of the two journals have produced a common set of guidelines for authors based on the seventeenth edition of the Chicago Manual of Style. On a few matters the respective styles of journals differ—how to format the opening page and section titles, placement of author biographies, etc.—and these will be noted in the guide.
