St. Christopher is often depicted as a patron saint of travelers and is known for the popular phrase "Christ be with me, Christ within me, Christ behind me, Christ before me, Christ beside me, Christ to win me."

Aside from doctrine and dogma, the answer is in the name. Christians are the followers of Christ. The word literally means "Christ Like." The ministry of Christ as depicted in the New Testament literally states "Jesus answered, 'I am the way and the truth and the life. No one comes to the Father except through me.'" From a Christian perspective, this is salvation, and the only way to "be a Christian" is to be saved.

A Cross is not a symbol of Christ's death but his resurrection. Some churches , notably Roman Catholic and some Orthodox churches use crucifixes - i.e. crosses on which are depicted the figure of the dying or dead Christ, in order that they remember the death of Christ. Im other churches, however, the Cross is empty - symbolising the resurrected Christ, and it is this aspect of our faith that we remember when a cross is used in Church. They are often used on a communion table, or as any focal point within the building.
