Guy returned to California in 1984 to serve in a pastoral position at the Loma Linda University Church, returning to the La Sierra campus as its president after it became an independent institution in 1990. He re-joined the La Sierra religion faculty full time in 1993 as a professor of theology and philosophy, transitioning in 2002 to research professor of philosophical theology.
While a student at La Sierra, Guy met his future wife, Marcia Specht. They married in 1954 and had three children. Marcia Specht Guy died in 2006 and the Marcia Specht Guy Memorial Prize, awarding winners of La Sierra’s annual concerto competition, is named in her honor.
“Fritz taught hundreds and hundreds and hundreds of seminary students at Andrews including me,” said La Sierra University President Randal Wisbey in introducing Guy. “And as a result of those many classes and lectures, his impact on the ministry of the Adventist church is still being felt today. I want to thank you for what you’ve given to each and every one of us.” He cited Guy’s contributions to Seventh-day Adventism and commended his character. “He is a genuinely caring, gracious, Christian human being. Dr. Guy is to this day deeply loved by La Sierra’s students,” said Wisbey to cheers from the audience, which included many students.
Richard Patchett, president of the Class of 2012 said, “he challenges us to be brave, to seek truth and not be afraid to ask difficult questions. [He has] guided us and given us wisdom when we had no idea what to do. He has shown us God’s limitless love and grace.”
Guy told the audience he learned from his La Sierra Professor Edward Heppenstall that “La Sierra is a place that is safe to think, a place that is safe to question answers. …I was unspeakably blessed by my time here [as a student]. Those four years changed my life, because they gave me the idea of how exciting it can be to think theologically. I am proud to be part of La Sierra and I plan to stay here as long as I can possibly be useful to this place,” he said.
