Protestant churches, for the most part, do not believe in making the sign of the cross with their fingers. Neither do they bow down before crosses or use them as objects of worship. They have recognized that these things are unscriptural and superstitious. But the use of the cross has been commonly retained on steeples, on pulpits, and in various other ways as a form of decoration.
The early Christians did not consider the cross as a virtuous symbol, but rather as "the accursed tree", a device of death and "shame" (Heb. 12:2). They did not trust in an old rugged cross. Instead, their faith was in what was accomplished on the cross; and through this faith, they knew the full and complete forgiveness of sin! It was in this sense that the apostles preached about the cross and gloried in it (1 Cor. 1:17, 18). They never spoke of the cross as a piece of wood one might hang from a little chain around his neck or carry in his hand as a protector or charm. Such uses of the cross came later.
It was not until Christianity began to be paganized (or, as some prefer, paganism was Christianized), that the cross image came to be thought of as a Christian symbol. It was in 431 that crosses in churches and chambers were introduced, while the use of crosses on steeples did not come until about 586. In the sixth century, the crucifix image was sanctioned by the Church of Rome. It was not until the second Council at Ephesus that private homes were required to possess a cross.
