Franz Bos személyét azért választottuk bemutatásra, mert esetében megtalálható a titkos rendőrség munkamódszerének valamennyi eleme: a szigorú határellenőrzéstől a részletes ügynöki jelentéseken, figyelmeztetésen és a több irányú technikai eszközalkalmazáson át egészen a nyomkövetésig.
The second half of the 20th century can be characterised by a consolidation of all state structures of the Communist Party. The most important institution in keeping the power was the Secret Police (Securitate), which exercised a strict control over the Churches, including the Hungarian Reformed Church. The Securitate was mostly interested in the foreign contacts of the church.
During the Communist regime, in the sixties of the 20th century, the Protestant Theological Seminary started the student exchange program with churches and institutions from the Western part of Europe, mainly the Dutch Reformed Churches. It was in 1968 when the first Dutch couple came to spend one study year in the Seminary. After them students have been arriving each year until the end of the eighties. Coming from a capitalist, “unfriendly” country, the Dutch students have always been watched at by the Securitate (Secret Police) very carefully.
