Which country's flag has an open bible within it’s central coat of arms?

The flag of the Dominican Republic has an open bible within its central coat of arms.

Christopher Columbus visited the island of Hispaniola in 1492, claiming it for the Spanish monarchy. However, French colonists in the 17th century established a state known as Saint-Domingue (Saint-Dominique) in the western part of the island, which subsequently became Haiti. The Spanish-speaking area in the east was conquered by the newly independent Republic of Haiti in 1822.

One of the national flags of Haiti had equal horizontal stripes of blue and red, and it was that flag that formed the basis for the revolutionary banner eventually raised in the Spanish-speaking areas. Dominican Republic achieved independence in 1844.

The flag of the Dominican Republic is composed of a relatively large white cross that divides the flag into four fields. Upper left field and the lower right field have a blue colour. The remaining two fields are red. In the middle of the cross, there is a coat of arms. The coat of arms incorporates on its central shield the national flag, a Bible, and a cross, together with branches of laurel and palm, the name of the country, and the motto “Dios, patria, libertad” (“God, fatherland, liberty”). With some artistic variations, the flag has continued in use to the present day.
