In St. Matthew's gospel, Jesus asks his disciples: "Whom do men say that I, the Son of Man, am?" (KJV)
On the first Wednesday of Lent, Rabbi Victor Urecki of Charleston congregation B'nai Jacob gave the answer for Orthodox Judaism, a modern orthodox group that observes the Rabbinical 613 Commandments of Moses.
When the Orthodox speak of the Commandments, they refer not to the Decalogue, the 10 Commandments familiar to Christians, but to 365 positive directives and the 248 negative ones formulated after Mt. Sinai.
Nearly 1/3 of these commandments relate to animal sacrifice in the Temple, the second of which was destroyed by the Romans in the year 70 C.E. (Christians say A.D. for Anno Domini) but to Jews of all stripes, Jesus' birth has no special significance. Thus the "C.E." means the "common era" and B.C.E. is "before the common era." These designations are used by scientists too.
Few Christians have probably read the regulations pertaining to blood sacrifice in the Temple. They are contained in the book of Leviticus in the Tanakh, the word Jesus used for what Christians call the "old testament" (to say old testament is to imply that there is a "new testament," which for obvious reasons, Jews are reluctant to do.)
Episcopalians are, of course, the economic "cream" of Christianity, topping all other Protestant denominations by a wide margin in average income, e.g., the chapter titled "The Long Road from Pentecostal to Episcopalian" in Vance Packard's "The Status Seekers" of a few decades back. I passed from Methodist to Episcopalian a decade or so ago, primarily because of the regular Eucharist. I am on my way to the Roman church, but have troubles, e.g., with the notion of the Blessed Virgin's bodily ascension into Heaven, sans scriptura or other contemporary source.
However, I would suggest that it is impossible to understand Christianity except in the context of Temple sacrifice. The liturgical churches regularly intone "Behold the Lamb of God that taketh away the sins of the world . . .," just as the high priest did.
It was to an audience of 100 or so Christian faithful that Rabbi Urecki brought the message, a people that since King Henry VIII considered themselves as the "chosen," supplanting the Jews. The Rabbi stood behind a small table and deftly fielded a couple dozen questions from people who wanted to know if he believed Jesus was the "Son of God" (What does Islam say?" he retorted) to a woman's complaint about not being able to be buried with her Jewish husband. (Different rules.)
