When I was younger, I didn't understand the phrase "Judeo-Christian tradition." Now I understand a little better. Both Jews and Christians have some common directives, like visiting the sick. (Other religions that trace their common origin to Abraham, including Islam and the Baha’i faith, also tell their people to visit the sick.)
This past Monday, Sept. 29, in the Milwaukee Journal Sentinel, there was a beautiful, beautiful article on visiting the sick. The article explained how this tradition is a holy mitzvah (good deed/duty/ commandment) of the Jewish faith.
