Cygnus-
Totally agreed when you stated,
"I can't imagine labeling one's self as a Christian and not 'partaking of the emblems'"
These elitist false prophets and Anti Christs known as the G.B. and their predecessors (from the days of the evil slave Joseph Rutherford) have prevented millions from having a true Christian experience. I partook with them (in the KH), and partake having left them. So when I visit different denominations I partake if they are partaking. I have partaken with Baptists, Pentecostals, Methodists, Catholics (bread only), Presbyterians, Adventists, and numerous other gatherings.
Christianity is a mystical daily experience unless one gets railroaded by a cult. Matter of fact, there is total mystery in Christianity after one leaves texts, commentaries, prophecy, and the words of men. What's left -- Christ! Mind you, I was raised to be an Orthodox Rabbi, did my stint with the JWs, studied Eastern religions and Old/New Age gurus, perused Western isms, and then lo and behold... "I am the Way, the Truth, and the Life." Just Jesus, and no religion. The sacrament/emblems are devoid of who puts the bread, wafer, matzos, or crackers on the plate. It's the Christian partaking of the mystery and that's a new beginning.
To those confused by my explanation, there are no further words, for words can't adequately define the mystery, and needless to say for that reason, the mystery can not be taught by man with words.
