The aim of the article is to verify the hypothesis that the institutions of diocesan synod in the perspective of the Roman Catholic Church and that of the Evangelical Church of the Augsburg Confession in the Republic of Poland are very similar. The method to achieve the aim is the comparable analysis of the legal provisions of the fundamental laws of the Churches which refer to diocesan synod. The general conclusion is that the institutions of diocesan synod seen in the two perspectives are completely incompatible. They are different institutions.
