“Every reader of this fine collection will come away having learned something interesting about the Scottish Reformation. Scholars will use it as an important resource for years to come and its many chapters and their detailed bibliographies will lead historians to new insights on ideas that are most fundamental to understanding Scotland in the past or the present.”Daniel MacLeod, University of Manitoba. In: Journal of Jesuit Studies, Vol. 10, No. 1 (2023), pp. 154–156.“The standard of these chapters is very high. Each is followed by a considerable bibliography that features primary and secondary sources. One reaches the conclusion that, especially for those who desire to teach this era to others, yet who lack access to a research library in which materials on this era are well represented, this Companion would prove to be an indispensable aid; it is—in essence—a consolidation of current research in this field.”Kenneth J. Stewart. In: Calvin Theological Journal, Vol. 57, No. 2 (2022), pp. 407–410.“This is an excellent overview of a diverse array of issues and developments in the study of the Reformation in Scotland.” Gregory Soderberg, Redemption Seminary. In: Journal of Reformed Theology, Vol. 17, No. 1 (2023), pp. 102–103.
