Understanding the attitudes of church institutions in the course of history is, first of all, to understand the men and the women who make them in its nature, its ontology, regardless of their religious belonging. In the light of memory concepts, thought by Ricoeur and Halbwachs, this Paper seeks to deal with practices of exclusion, fostered between 1970-2000, among two communities of Ukrainians which arrived to southern Brazil in the late 19th century. Thus, the little proximity between Ukrainian Catholics of the Eastern Rite and Orthodox ones, strongly linked to small and large disagreements of the past, has become an object to be analyzed and understood within the dynamics of memory that unfolds through the time. Therefore, it seeks to historicize the emergence of these two ethnic-religious segments until they came ashore in Curitiba in the 20th century and the consequent indemnity repercussions unfolded in promoting actions that crippled proximities.
