Stefan Haas is a graduate theologian, Bible teacher, author, co-founder and pastor of TOS Church in Leipzig. In 2000, he initiated and organized a continuous 24/7 prayer (day and night prayer) as a central spiritual element of the church. As a long-time organizer, he has shaped Leipzig's commemorative events as part of "March of Life" as well as the exhibition "Never Again Silence", which has had its home in the kosher Café HaMakom since 2015 and has developed into an important place of Jewish-Christian encounter in Leipzig.
