What are some of the purposes of christian art?

The passage states, "Artists use their artworks to express their own faith or to describe Biblical events and views on Christianity. Often, their works are designed to have a special effect on the viewer. Some works of art are devotionals, designed to make the viewer think deeply about faith and beliefs. Other works are intended to teach the viewer. Some works are dramatic and emotional, used to make the viewer feel a sense of love, fear, or respect for Christianity. And some artworks are used in Christian rituals." This tells us here that Christian art is used for many different reasons. Some purposes would be for influencing, teaching, or portraying events.
