 In the seventeenth and eighteenth centuries, Christian theosophy and Pietism arose in response to the orthodoxy of the Lutheran Reformation.The work of the 17th-century German Christian mystic Jakob Boehme (1575–1624) strongly contributed to spread the use of the word "theosophy", even though Boehme rarely used the word in his writings.It is on account of the title of some of his works, but these titles appear to have been chosen more by the editors than by Boehme himself.
