A strictly orthodox theologian and a clear writer, Luthardt became widely appreciated as the author of apologetic lectures. These were collected under the title Apologie des Christentums (vol. i., 1864, 14th ed. 1896; vol. ii. 7th ed., 1901; vol. iii. 7th ed., 1898; vol. iv. 2nd ed., 1880), a work of which the first three volumes have been translated into English.[5] In 1868 he founded and edited the Allgemeine Evangelisch-Lutherischen Kirchenzeitung,[6] with its supplement, the Theologisches Litteraturblatt, and in 1880 became editor of the Zeitschrift für Kirchliche Wissenschaft und Kirchliches Leben.[5]
