The Ökumenische Heiligenlexikon (ÖHL) or Ecumenical Lexicon of Saints is an independent, ecumenical, private internet project by Protestant priest Joachim Schäfer, from Stuttgart, which aims to publish information on the lives of saints and other "holy people".
The lexicon is the largest and most comprehensive online repository of information on saints and other people considered blessed or holy. The basis of the collection are sources that are generally accessible, especially reprinted church history works. One aim is to edit out conflicting and false information, without making any claim to be scholarly. Volunteers with relevant expertise help the project with information and check articles for correction.
