In The Evolution of Religion, vol. 2, Caird establishes Judaism as a religion of subjectivity. From Judaism he moves to Christianity, the teaching and the work of Christ, who fulfilled and abolished the religion of Israel. Having summarized the teachings of Jesus, the author considers the way in which St. Paul at once generalized and idealized the faith of Christ, liberating it from the Judaic conditions of its origin and at the same time lifting it into the region of theology. Caird further discusses the general characteristics of the evolution of Christianity in post-apostolic times and the development of Christianity before and after the Reformation. Finally, he notes the hindrances and aids to faith in the present day, 1891–1892.
