Do you believe that it is a sin to have a cross in or on a christian church?

There is at least one christian religion that believes that it is a sin to have a crucifix or cross displayed anywhere on a church such as on the steeple. It's members thinks that it is not biblical. What do you believe?
Update: The campbellite church of Christ, Charchar.
Update 2: Good points about "denomination" and "religion" respectively, Raquelita and Mr X.
