In 1838, the first edition of "The Kingdom of Christ" was published. It was "one of his most significant works." A second enlarged edition was published in 1842 and a third edition in 1883. For Maurice the signs of this kingdom are "the sacraments of baptism and the eucharist, to which must be added the creeds, the liturgy, the episcopate, and the scriptures—in fact, all the marks of catholicity as exemplified in the Church of England." The book was met with criticism when published, a criticism "that lasted throughout Maurice's career."
