Cross in Eternity
The symbol of the cross and circle, also known as the Cross in Eternity, depicts the suffering and the death of the Lord Jesus Christ for the sins of the world. The circle symbolizes eternity since its circumference is an endless line. The cross in eternity gives the concept of the completeness and the everlasting nature of Christ's work and Kingdom.
The cross is always a reminder of our Lord's saving work of redeeming mankind through His sacrifice for our sins, thereby bringing forgiveness and salvation.
The fish is one of the earliest and most complex symbols employed by Christians to represent the Savior. Reading the initial of the Greek acrostic phrase meaning "Jesus Christ, Son of God, Savior," one obtains the Greek work for "fish," Ichthus.
The fish symbol was probably used by the persecuted Christians as a means of avoiding unpleasant attention of the Roman police. The symbol of the fish is one of the most widely used symbols depicting the Lord Jesus Christ and the Christian belief that He is indeed the Son of God and Savior of the world.
