Who can apply ?
Religious workers include ministers of religion who are authorized by a recognized denomination to conduct religious worship and perform other duties usually performed by members of the clergy such as administering the sacraments, or their equivalent. The term does not apply to lay preachers. A religious vocation means a calling to religious life, evidenced by the demonstration of a lifelong commitment, such as taking vows. Examples include nuns, monks, and religious brothers and sisters. A religious occupation means a habitual engagement in an activity which relates to a traditional religious function. Examples include liturgical workers, religious instructors or cantors, catechists, workers in religious hospitals, missionaries, religious translators, or religious broadcasters. It does not include janitors, maintenance workers, clerks, fund raisers, solicitors of donations, or similar occupations. The activity of a lay-person who will be engaged in a religious occupation must relate to a traditional religious function: i.e., the activity must embody the tenets of the religion and have religious significance, relating primarily, if not exclusively, to matters of the spirit as they apply to the religion.
