"Edward is a Christian name"
Edward Roffman tells us, “I grew up in Brooklyn, New York, in a home with strong Jewish roots. My parents are both fluent Yiddish speakers, and my identification with Judaism has always been strong, although worship and ritual observance were not major components in my upbringing. My discovery of the vitality of worship and the importance of observance has constituted a major journey of my adult life.
“I love teaching prayer, song, chant, and the myriad facets of our Jewish tradition to adults and children. I envision my teaching to be similar to gardening. Some of the seeds that I plant will take root quickly, and some may not germinate or grow for many years. The process of my own personal development as a Cantor was influenced by seeds of Jewish learning that were planted in me as a child. It is a privilege to have the opportunity to develop and encourage appreciation of the immeasurable joy of Jewish worship within my congregation, B'nai Israel in Basking Ridge, New Jersey.
Edward is a Christian name, in that is recognizes St. Edward. I would imagine that Edward Roffman's Hebrew name is not "Edward" though. And I certainly wouldn't bet the farm on the fact that Edward McDonald is the son of two fluent Yiddish speakers.
Which is not to say there are no Irish Jews, just to say that Edward McDonald is probably a nominal Christian. And certainly an accused murderer.
