The cross is sometimes shown as a tree. This tradition comes from the belief that the tree used to make the cross of Christ was an off-shoot of the Tree of Knowledge in the Garden of Eden.
In Genesis, the first book of the Old Testament, Adam and Eve eat fruit from the Tree of Knowledge, even though God forbids them to do so. The sins of Adam and Eve symbolise the sins of all men and women, which are redeemed by Christ's sacrifice.
