This emblem is similar to the flag design and shows a bible, a cross of gold, 4 Dominican flags and two spears on a pattern from the flag. there are bracches of olive and palm around the shield and above on a ribbon is the motto “Dios, Patria, Libertad” meaning “God, Fatherland, Liberty”. Below the shield is the name of the country “República Dominicana” appears on a red ribbon (this red ribbon is depicted in more recent versions as having its tips pointing upward). In the center of the shield, flanked by three spears (two of them holding Dominican banners) on each side, is a Bible with a small cross above it and said to be opened to the Gospel of John, either to chapter one or chapter 8, verse 32, which reads Y la verdad nos hará libre (And the truth shall make you free).
