[R-390] BTW#2 ( was Nuvistaplug?)

Sun Dec 25 21:14:56 EST 2005

"X" is the Greek letter "chi", the first letter in the word for Christ.
Many times, the early Christians combined "chi" and "rho" (the first two
letters in the word "Christ") together to make a chi-rho symbol which was
"code" for "Christ" and was used by early "underground" Christians.  At
least that's what my history books told me in HY-102.
