Which is the smallest country to have a national flag with a Bible on it?

The Dominican Republic is the smallest sovereign country whose national flag depicts an open Bible, covering about 48,671 square kilometres.

The flag has a white cross dividing blue and red quarters. At the center is the national coat of arms, which includes an open Bible, a small cross, and the motto “Dios, Patria, Libertad,” meaning “God, Fatherland, Liberty.”

The design is associated with the Dominican independence movement and was created by Juan Pablo Duarte, a leading founder of the country. The flag was first used in 1844, when the Dominican Republic declared independence from Haiti.

The Dominican Republic shares the island of Hispaniola with Haiti, but the two countries have different flags and historical traditions. This question concerns sovereign national flags, not regional, provincial, or historical flags.
