The present scientific article’s theme is the relations between the pope ante the bishops. It aims to reflect, through the biblical, historical and theological arguments, how the exercise of the Petrine ministry and its repercussions in the episcopal ministry should be systematized and understood. For this purpose, the explicative research method was applied, together with bibliographical study. Thus, the exercise of the Petrine ministry can be understood only from the episcopal collegiality, being the head of the college of bishops, but also as promoter of the action of the episcopal body, singularly or as a whole. Therefore, primacy and college are not juxtaposed or dichotomized entities, but complementary and integrated dimensions, made possible by episcopal communion.
