Should you wear a cross or crucifix?
Wearing the Crucifix among the Christian community also varies, among each denomination. For example, whilst Catholics display the Crucifix in their churches and often wear Crucifix's or carry them for prayer and protection, people of the Protestant faith wear a plain cross.
The most marked difference between a cross and a crucifix is the corpus or body of Christ on a crucifix. Some Protestants object to the crucifix because of the belief (which we Catholics share!) that Christ is resurrected, not still on the cross and thus, (some believe) He should not be depicted that way.
The use of crucifixes by Catholics follows an ancient tradition that honors the supreme sacrifice of Jesus. While the empty cross is a common Christian symbol shared by all Christian churches, Catholics stand out for their frequent use of the crucifix, a cross that shows the tortured body of Jesus Christ.

Who uses a crucifix?
A crucifix (from Latin cruci fixus, meaning "one fixed to a cross") is a cross with a representation of Jesus' body, or corpus. It is a principal symbol of the Christian religion, primarily used in the Catholic, Anglican, and Eastern Orthodox Churches.
A number of Protestant churches and homes display an empty cross, without a depiction of Christ, to memorialize the Crucifixion while representing the triumphant defeat of death in the Resurrection.

Displaying a crucifix in your home is a soothing reminder that during life's trials we're not alone and “someone gets it.” What's more, the crucifix reminds us that just like Jesus if you persevere through the difficult times, you'll get through it and ultimately be rewarded.
