The ichthys, or fish symbol, is one of the earliest Christian symbols. It was used by early Christians to secretly identify themselves to one another during times of persecution. The word "ichthys" is Greek for "fish" and is an acronym for "Jesus Christ, God's Son, Savior."
The Chi-Rho symbol is a monogram of the first two letters of the Greek word for Christ, "ΧΡΙΣΤΟΣ." It is often used as a symbol for Jesus Christ. The Chi (Χ) and Rho (Ρ) are superimposed or combined into a single symbol. It's a powerful reminder of Christ's centrality in Christianity.
These are the first and last letters of the Greek alphabet, and they signify the eternal nature of God. In the Bible, Jesus identifies himself as the "Alpha and the Omega" to emphasize his timeless and unchanging nature (Revelation 1:8).
In early Christian art, the phoenix symbolized resurrection and immortality. Just as the phoenix is reborn from its own ashes, so too does the Christian believer experience spiritual rebirth and eternal life through Christ.
The image of Christ as the Good Shepherd is a well-known symbol. It represents Jesus caring for and guiding his flock, his followers, and is a reminder of his love, protection, and guidance.
