Chi Rho

CHI RHO - The first two letters, X (Chi) and P (Rho) in the Greek alphabet.  A monogram of chi (Χ) and rho (Ρ) as the first two letters of Greek (Khristos or Christ) used as a Christian symbol.  Although not technically a Christian cross, the Chi-Rho invokes the authority of Jesus, as well as symbolizing his status as the Christ.
