From November of 1975 until October of 1978 Prof.Herman Hanko emeritus PRC church history professor) wrote a lengthy series (23 articles) on Rev.George M. Ophoff (1891-1962) for the Beacon Lights (PR Young People’s magazine).
I was mistaken about this series being absent from the current “BL” archives. They are in fact there, but you have to choose the “complete issue” option in the upper right-hand side of the homepage. Then you locate the issues in the span given above.
In the meantime, enjoy this page from the eighth article on Ophoff (June/July 1976 issue), which covered his years at Calvin Seminary, when the common grace debate in the Christian Reformed Church (CRC) was getting started.
