“ Among church historians Gieseler continues to hold a high place. Less vivid and picturesque in style than Karl Hase, conspicuously deficient in Neander’s deep and sympathetic insight into the more spiritual forces by which church life is pervaded, he excels these and all other contemporaries in the fulness and accuracy of his information. ”

“ Gieseler was not only a devoted student but also an energetic man of business. He frequently held the office of pro-rector of the university, and did much useful work as a member of several of its committees. ”

“ In 1837 he was appointed a Consistorialrath, and shortly afterwards was created a knight of the Guelphic order. He died on the 8th of July 1854. The fourth and fifth volumes of the Kirchengeschichte, embracing the period subsequent to 1814, were published posthumously in 1855 by E. R. Redepenning (1810–1883) ”
