Yusak Soleiman pleads for integration of the 200 years of the VOC as part of the history of the Protestat Church, also in Java: "My intention is to bring to the light the onknown and forgotten past of the early Christian community in Java. Historians of the Christian Mission tend to see only shortcomings in the first 200 years of Protestantism in the Indonesian Archipelago" (199)
In 2002 Yusak held the lecture to commemorate the foundation of the STT and it had the crusades as theme. Now he has written a book of 182 pages, Perang-perang Salib, hantu dari masa lalu, bagi masa kini dan masa depan bersama Islam dan Kristen? (Preface by Prof. Noorhaidi Hasan; Jakarta: Grafika Kreasindo).
Pages 39-130 give detailed information about the actual crusades: many waves of attacks from Europe, somewhat successful, often a disaster. For an Indonesian the travelling in Europe itself is not so interesting and this section of the common story is skipped here. Much attention is given to the better organization of the politics in Muslim lands, especially the Seljuks and Saladdin. There is also much self-criticism: Western Christian attacked the Greek Christian in Contantinople.
The book ends with two questions: "If heaven is the reward for the killing of faithful of other religions, do we then really want to enter this heaven? If my salvation depends on the destruction of other people, what kind of God will offer us this salvatioon?" (178).
