Final Answer:
The conflict based on perceived differences between divisions or sects within religion is called "Denominationalism."
Explanation:
Denominationalism refers to the divisions or conflicts within a religion due to varying interpretations of beliefs, practices, or traditions. These differences often lead to the formation of separate denominations or sects within the same overarching religious faith, each with its distinctive doctrines, rituals, or organizational structures.
Denominationalism can sometimes result in tensions, disagreements, or conflicts among these sects due to their perceived differences in religious interpretation or practice.
