As the very title of Lonergan's work, Method in Theology, may suggest, that Method stands in contrast to the theological 'method' then in vogue in seminaries: manuals.  These manuals were crafted in Latin, and were meant to be memorized by the students.  The Latin was so-called "church Latin," not the soaring Latin of Cicero or even Caesar, which most seminarians had not truly mastered!  So, Lonergan's Method was an early -- and excellent -- book for seminarians and theologians everywhere!  And in many instances, the students were more at home with "Method" than were their credentialed professors!
