The Monogram of Christ
The Greek letters X (Ch) + P (R) are the first two letters of the Greek word ΧΡΙΣΤΟΣ pronounced ‘Christos’.
These initials are known as…The Monogram of Christ…..CHR = XP.
For those who are not familiar with the Greek Alphabet, perhaps this explanation will be helpful.
The Greek letter X = Ch and the letter P = R (The letter that looks like a P in English is a Greek R.) In English the monogram would read CHR, and in Greek it would be written as XP and pronounced /Chi-Rho/
This symbol is composed of the P superimposed on top of the X.
There were many Christian symbols used by the followers of Christ throughout the Roman Empire both East and West. Some like the fish are very early, as is the anchor.
Of course, crosses of every shape and kind have been used to indicate believers in Christ.
Symbols have been found at many early Christian places: in catacombs, tombs, on walls as graffiti, in mosaics, and on jewelry.
It is often coupled with alpha and the omega, as it is on the Young Christian father’s ring.
“I am the Alpha and the Omega, the First and the Last,the Beginning and the End.” Revelation 22:13
Since the 4th century, when it was given to Constantine on the eve of the battle that would make him emperor of the Roman Empire, Christians have worn the Monogram of Christ to represent the triumph of Christianity over Paganism.
From the earliest times the Chi Rho has not belonged to any one particular branch of Christianity, but has been a universal Christian symbol for all.
