Julius Wilhelm Martin Kaftan (30 September 1848 in Loit, North Schleswig – 27 August 1926, Berlin-Steglitz) was a German Protestant theologian.
Kaftan studied theology at the Universities of Erlangen, Berlin and Kiel.
Later on, he became a follower of Albrecht Ritschl, belonging to the conservative wing of the so-called "Ritschlian School".
[2] Unlike Ritschl, he placed particular emphasis on the importance of mystical experience in religion.
[3] In 1897 he first published Dogmatik, which was for many years a standard work for young theologians (8th edition, 1920).
