Kiai Sadrach (born in 1835 in Jepara – died in Purworejo, 14 November 1924) was an evangelist in Central Java, Indonesia.
Within the class session, he was being introduced to a senior namely Kiai Ibrahim Tunggul Wulung who is already being a Christian and is also coming from the same region, Bondo, Jepara.
Afterwards, He then went to Semarang where he met Kiai TUnggul Wulung who has already established Christians villages such as Banyuwoto, Tegalombo and Bondo in Jepara.
Sadrach became the leader of the Bondo congregation as Tunggul Wulung traveled to gain more followers.
When Tunggul Wulung went back to Bondo, Sadrach, in the age of 35, set out to Kediri and later on to Purworejo.
However, the relationship between Sadrach and Stevens-Philips continued as Steven-Philips is considered to be his formal caretaker with the Colonial ruler.
