This very brief overview of Christian history is a condensation of Robertson's multi-
volume series on the same subject, The History of the Christian Church from the
Apostolic Age to the Reformation. Though not possessing the same depth of the larger
work, Sketches is masterfully written and structured in its breadth of information, making
it perfectly accessible for interested laypersons and students looking to review. As a
scholar of Christian history, Robertson selects information carefully and strategically
as to maximize his readers' understanding without overwhelming them with copious
amounts of detail.
