Proselyte A new convert to some religion or religious sect. Among the Hebrews, proselytes were distinguished into two sorts: the first called proselytes of the gate, because suffered to live among them, and were those who observed the moral law only, and the rules imposed on the children of Noah; the second were called proselytes of justice, who engaged to receive circumcision, and the whole law of Moses, and enjoyed all the privileges of a native Hebrew.
