In the period from 1965 to 1980, seven concepts and two alternative concepts of a fundamental church law "Lex Ecclesiae Fundamentalis" circulated. However, this fundamental church law was never promulgated. Two alternative concepts were prepared by the Evangelist study group at Heidelberg and by the Institute for Canon Law at the University of Munich. They show clearly the sensitive points for the Evangelist canon lawyers, in comparison to the seven concepts by catholic canon lawyers. By publishing these nine concepts side by side, this Synopsis wants to be an essential tool in understanding the constitutional law thinking within the Church in the 20th Century.
