Q. 1. Why do Catholics have a cross or crucifix on the wall in their homes?
A. 1. Hanging a cross or crucifix on a wall in one's home is a Catholic tradition that goes back many centuries, as far back as the 5th and 6th centuries. While some have a crucifix embedded into the foundation of their house, others hang a crucifix on a wall in every room of their home. The hanging of a crucifix on a wall serves as a reminder of Christ's redemptive sacrifice. Also, the crucifix is a sacramental that is used as a devotion to Our Lord and as a guard against evil.
Prior to the 5th and 6th centuries, the Christians did not openly display the crucifix for two reasons. First, it was to avoid being subject to ridicule by the Pagans. Secondly, it was because the followers of Christ were hunted down and killed in the early days of the Church.
