While religious art can be used to decorate religious spaces, this is not its primary function. The primary functions of religious art are to express spiritual beliefs, convey religious narratives, and inspire spiritual contemplation.

Sacred art is the term used to describe the use of art to express religious beliefs and experiences. It is often used to refer to art that is created for religious purposes or that has a religious theme.

Ai Weiwei, Marina Abramović, and Anish Kapoor are all contemporary artists who have explored the relationship between art and religion in their work.
