Chapter V-K. Images for Veneration by the Faithful
278. In keeping with the Church's very ancient tradition, it is lawful to set up in places of worship images of Christ, Mary, and the saints for veneration by the faithful. But there is need both to limit their number and to situate them in such a way that they do not distract the people's attention from the celebration.  There is to be only one image of any one saint. In general, the devotion of the entire community is to be the criterion regarding images in the adornment and arrangement of a church.
