The objective proposed is to perform a mapping of religious pluralism in the urban area of the city of Pereira, with the intention of investigating the possibilities of dialogue with Christian confessions, and propose in accordance with the Magisterium, some guidelines for ecumenical dialogue in the city. A mixed character methodology was applied because it includes both quantitative and qualitative methods of a historical- hermeneutic type, using the structural survey and multiple case study as tools. This work is not directly an interdisciplinary theological reflection using a transcendental, narrative, critical hermeneutics method, but an investigation that pretends to show -with the help of the social sciences- the status of Christian religious plurality in the city of Pereira (social science method) and then indicating descriptively the Catholic teachings and guidance on Ecumenism (magisterium ), in order to reflexively propose some lines of action or guidelines to promote ecumenical dialogue (about works, doctrine, spirituality and about life) in this region of the country Among the most relevant results, it is evident that there is little presence of different Christian faiths and the presence of new religious movements is three times larger than the number of parishes in the Diocese Archpriesthood of Pereira, and the most of the faithful people interviewed belonging to the movements come from Catholicism. Besides, several interviewed pastors are willing to start a dialogue with the Catholic Church and the various religious groups in the city. Finally, a process of acceptance and recognition is not evidenced yet in the city, thus religious pluralism cannot be discussed but diversity and religious plurality; and moreover, the Diocese has not implemented any strategy to initiate dialogues with current religious movements existing in Pereira.
