Final answer:
The difficulty in fully grasping religious worldviews for modern westerners is mainly due to the cultural influence of dualism and different interpretations of religion.
Step-by-step explanation:
The difficulty in fully grasping religious worldviews for modern westerners is mainly due to the cultural influence of dualism in the Judeo-Christian-Islamic traditions. Dualism is the belief in the division between the material realm and the spiritual realm.
Westerners are often accustomed to the idea of a single supreme being with specific characteristics, and this can create challenges when trying to understand different religious perspectives that may have different concepts of the divine.
Additionally, individuals may have their own personal interpretations of their religion, which can further complicate understanding different religious worldviews.
