This article is the result of a study that discusses the paradigm of Langsa Aceh scholars (Islamic scholars) to overcome multiculturalism. This study also reveals the consistency of the agreement of Islamic scholars regarding exclusivity and inclusiveness; prevent the emergence of radicalism in the Islamic community, especially the urban areas of Langsa in Aceh. It discusses the phenomenon of recent recruitment by "brainwashing" in younger students because they filled with certain radicalistic ideologies. The teachings of Islamic education are more about claiming the truth of the religion itself and consider religion as the only one to achieve salvation (emphasizing claims of self-truth and safety). This research is qualitative with a descriptive-analytical application. Primary data obtained from in-depth interviews with sources of religious leaders, lecturers of Islamic Higher Education, teachers, non-Muslim students, and community elements. Reliability of piety in diversity and the paradigm of multiculturalism converted to statistical equations. Mathematical equations applied to the Cohen Kappa coefficient (a measure of authenticity) and measured between exclusivity and inclusiveness with the claims of self-righteousness and the safety paradigm of Islamic scholars. The level of agreement between the instruments assessed illustrates the reliability between assessors -IRR- the results of the informant's interview level of consensus are identified between the safety of the results of the consistency of the contract between piety and exclusivity, because self-claims show "lack" (kappa, 0.20-0.41) , while the agreement between service and safety is "very good" (kappa 0.81-0.90). With inter-assessor reliability, K = 0.89 with an extraordinary category.
