This volume contains a critical standard edition of the Heidelberg Catechism in the original German, and Latin, together with a revised English translation and modern German translation. The introduction provides a succinct but full account of the origin and formation of the Catechism, its reception in the different branches of the Protestant Church, and its fortunes in Europe and America; and compares its genius and theology with that of other Reformed and Lutheran confessions, both of earlier and later date.
