Some people use a fish sign. It looks like two curved lines. This is called the ichthys. 

The ichthys is a famous symbol for Christians. It looks like a fish made from two curved lines. The word comes from an old Greek word for fish. The letters in the word also act as a code. They stand for "Jesus Christ, God's Son, Savior." 
Many stories in the Bible use fish. Jesus had many followers who were fishermen. In one story, Jesus helped feed a large crowd with just five loaves and two fish. In another story, his followers caught 153 fish after following his advice. 
Some people think early Christians used the fish as a secret sign. They may have used it to find each other during hard times. They might have marked meeting places or tombs with it. Today, the symbol is very common. You can see it on car stickers or as necklaces. 
The ichthys is a well-known symbol used by Christians today. It is made of two arcs that cross each other. This shape looks like the profile of a fish. The name comes from the ancient Greek word for fish. For many, this simple shape holds a very deep meaning. It is often called the "Jesus fish" in modern times. People use it to show their faith to others.
The symbol works as a special kind of code. In Greek, the letters of the word "ichthys" form an acronym. This means the first letter of each word creates the name. These letters stand for "Jesus Christ, God's Son, Savior." 
History shows that this symbol has been around for a very long time. The first appearances in art and writing date to the 2nd century. By the late 2nd century, it was very popular among followers. It spread even more during the 3rd and 4th centuries. Some early writers, like Clement of Alexandria, suggested using it. Others, like the Church Father Augustine, wrote about its meaning. 
Many stories in the Gospels connect Jesus to fish. Several of his twelve Apostles were fishermen by trade. In one story, Jesus fed five thousand people with five loaves and two fish. In another, his disciples caught 153 fish after following his advice. Jesus even told Peter he would find a coin in a fish's mouth. These stories help explain why the fish is so sacred. The fish is a key part of Christian history and teaching.
Today, the ichthys is a common sight in our daily lives. You might see it as a sticker on the back of a car. 
The ichthys is a significant symbol used by Christians to express their faith. The name comes from the ancient Greek word for fish, which is spelled ΩΧΘΥΣ. In its modern form, the symbol consists of two intersecting arcs. The right ends of these arcs extend beyond the meeting point. This specific design creates the profile of a fish. Today, many people colloquially refer to this icon as the "Jesus fish." It serves as a visible sign of religious identity for many believers.
The symbol functions as a complex acronym or acrostic. In the Greek language, the letters of the word ΩΧΘΥ represent the first letters of a specific phrase. This phrase translates to "Jesus Christ, God's Son, Savior." 
There are different ways to interpret the visual forms of the ichthys. The most common version is the simple fish outline. However, a 4th-century adaptation exists that is more complex. This version superimposes the Greek letters on top of one another. This process creates a shape that resembles an eight-spoked wheel. While many scholars interpret this as a wheel, others suggest it represents a loaf of bread. These variations show how the symbol evolved to include different layers of meaning over time.
The history of the ichthys spans nearly two millennia. The first appearances of the symbol in Christian art and literature date to the 2nd century. By the late 2nd century, its use among Christians had become quite popular. The symbol then spread widely throughout the 3rd and 4th centuries. Some historians have debated how it was used during times of Roman persecution. It was once suggested that Christians used the fish as a secret symbol to identify one another. This idea was popularized by the 1951 movie *Quo Vadis*. However, many modern scholars now believe this "secret symbol" theory is less likely. They point out that early sources link the fish more to sacraments than to hiding from authorities.
Archaeological evidence provides concrete links to the early church. The symbol has been found in several important locations. For example, it appears in the Catacombs of Saint Sebastian and the Catacomb of Priscilla. 
The connection between Christianity and fish is rooted in several Gospel stories. Many of Jesus' twelve Apostles were professional fishermen. In the Gospel of Mark, Jesus tells them he will make them "fishers of men." Other stories include the feeding of the five thousand, where Jesus used five loaves and two fish. In the Gospel of John, the disciples catch exactly 153 fish after following Jesus' instructions. Another story in Matthew describes Peter finding a coin inside the mouth of a fish. Even the "Sign of Jonah" uses fish imagery to symbolize the resurrection of Jesus.
In modern popular culture, the ichthys has seen a significant resurgence. During the 1970s, the "Jesus Fish" became a popular icon for believers. It was even brought to the Aquarius Rock Festival in Australia in 1973. Today, the symbol is frequently seen on vehicles as a decal or emblem.
