Chi Rho Christogram Labarum - Christian Symbols

Christian symbols

Visual representations and signs - also known as symbols - are very important in the Christian religion. Christians may be called "people of the book" (meaning they are readers of the Bible) and "people of faith" (meaning they believe in unseen things). Still, imagery plays an important role in the Christian life. For instance, symbols incorporating colors, shapes, and numbers, can have significant importance in the right context.

While faith apart from the senses may be of primary importance in Christianity, believers recognize that God is also the creator of the human senses, including sight. Moreover, what is visible and physical can, under the right circumstances, be an aid to faith. For example, when Christians remember the cross of Jesus Christ, in accordance with biblical instruction (e.g. 1 Corinthians 11), they consume bread and wine (or similar elements) at the Lord's Supper.

Faith is thereby supported by a sensory experience.

Chi Rho in Christianity

The Chi-Rho (pronounced "KEE-roe") is a Christian symbol consisting of the intersection of the capital Greek letters Chi (Χ) and Rho (Ρ), which are the first two letters of "Christ" in Greek (ΧΡΙΣΤΟΣ, Christos). The Chi-Rho can represent either Christ or Christianity and is also known as a Christogram.

Chi Rho and Constantine

The Chi-Rho is also known as the labarum, which is based on the Latin word laureum, "military standard."

This is based on Constantine's application of the Chi-Rho symbol to his military standard after receiving his famous vision before the Battle of the Milvian Bridge in 312.

The church historian Eusebius, who spoke with the emperor about his experience, described the standard:

"On the top of the whole was fixed a wreath of gold and precious stones, and within this the symbol of the Saviour's name, two letters indicating the name of Christ by means of the initial letters, the letter X intersection P at the center."

The Chi-Rho was used by Christians before Constantine but it became much more widespread after he adopted it.

The chi-rho appeared on the coins of Constantine and his Christian successors, sometimes alone and sometimes as part of a military standard as described by Eusebius. It continues to be widely used today.
