author
Best known today for a single surviving 1888 study, this little-documented writer took on a big subject: how Christian doctrine took shape across history. The result is a compact, argumentative work that still feels bold in its scope.

by Charles A. H. Tuthill
Very little biographical information about this author could be confirmed from reliable sources found during this search. What can be verified is that Charles A. H. Tuthill wrote The Origin and Development of Christian Dogma: An Essay in the Science of History, published in London by Kegan Paul, Trench & Co. in 1888.
That book approaches Christian doctrine historically rather than devotionally, tracing how beliefs developed through the interaction of different religious traditions and historical conditions. Its continued availability through library and public-domain catalogs suggests it has remained of interest mainly because of that ambitious, analytical study.
Because solid personal details such as birth dates, education, career, or a fuller bibliography were not clearly confirmed, it is safest to see Tuthill as a late-19th-century author remembered chiefly for this one work on the historical development of Christian dogma.
