The purpose of steeples on church buildings was originally to serve as a bell tower and sometimes a clock tower. In the days before people had clocks or wrist watches, the ringing of the bell would signal that it was time to come to church. The bell was also used to signal other community events. Today they are mostly decorative and don't serve any practical purpose other than perhaps holding a lightning rod. We do not believe they have any moral consequences. Under the New Testament, the church is a group of people, not a building. What the building looks like that the church meets in is not relevant to the purposes of God.
