Proselytism /ˈprɒsəlɨˌtɪzəm/ is the act of attempting to convert people to another religion or opinion. The word proselytize is derived from the Greek language prefix προσ- (pros-, toward) and the verb ἔρχομαι (érchomai, to come) in the form of προσήλυτος (prosélytos, a new comer). Historically in the Koine Greek Septuagint and New Testament, the word proselyte denoted a gentile who was considering conversion to Judaism.
