Question: what is the px christian symbol?
Answer: The Chi Rho (/ˈkaɪ ˈroʊ/; also known as chrismon) is one of the earliest forms of christogram, formed by superimposing the first two (capital) letters—chi and rho (ΧΡ)—of the Greek word ΧΡΙΣΤΟΣ (Christos) in such a way that the vertical stroke of the rho intersects the center of the chi.
