Cross or Crucifix?
Do you know the difference between a cross and a crucifix? A cross shows just the two logs attached like a "plus sign." A crucifix is a cross that shows Jesus' body on it.
Here you can see the crucifix that hangs above the altar. The crucifix in your church may look different. This one shows Jesus after he rose from the dead. It is called a Cross of Resurrection. Other crucifixes show Jesus dying on the cross.
Either way, seeing the crucifix reminds us of Jesus' great sacrifice for us.
