Parish Nursing: a speciality practice and professional model of health ministry. A Parish Nurse is an experienced registered nurse in good standing with the Professional governing body or association. A Parish Nurse links faith and health to combine professional nursing with Christian ministry. The Christian Church mandate is to preach, to teach and to heal. I believe there are also some Jewish Parish Nurses as well although I haven't met any as of yet. Hope this is helpful. Do a internet seach and you will find hundreds of entries.
