This volume distills lectures given by B. F. Westcott to students at Cambridge on Christian doctrine. He notes that “the thoughts which they contain have been constantly tested in private discussion, and I have found them guidance and support in looking at the spectacle of the world—of man and of nature—full as it is of sufferings and sorrows and failures.” This volume explains how “Christianity offers in a real human life the thoughts by which other religions live. Nature herself does not give an answer to the riddles which she proposes; but the whole life of men points to the answer which Christianity has given.… Christianity is in life and through life. It is not an abstract system but a vital power, active through an organized body.”
