Final answer:
Judaism is the universalizing religion that traditionally does not try to convert people, focusing instead on its existing community and not on proselytization.
Step-by-step explanation:
The universalizing religion that does not actively try to convert people is Judaism. Unlike Christianity, Islam, and Buddhism, which are known for seeking new members, Judaism traditionally does not proselytize or seek to expand its faith through conversion. The focus of Judaism is largely on the community of people born into the Jewish faith or those who join through an intensive conversion process, rather than actively encouraging conversion of others. In Judaism, the concept of being 'chosen' pertains more to a unique historical relationship with God rather than a mission to universalize the religion.
