The Catholic Vietnamese Holy Bible is an app that provides access to the Catholic Bible in the Vietnamese language. It includes books from both the Old Testament and the New Testament, as well as several books that are excluded by Protestant Bibles. The app offers various translations of the Catholic Bible, including the New American Bible (NAB), the Revised Standard Version - Catholic Edition (RSV-CE), the Douay-Rheims, and the Navarre Bible.

One of the key differences between the Catholic Bible and other translations is the inclusion of the deuterocanonical books, also known as the Apocrypha, which are not found in Protestant Bibles. Additionally, the Catholic Bible's canon of Old Testament texts is larger than that of Protestant translations, as it includes books that are based on the longer Hebrew and Aramaic Masoretic Text.

The Catholic Vietnamese Holy Bible app provides a valuable resource for Catholics who prefer to read and study the Bible in the Vietnamese language. With its wide range of translations and comprehensive collection of books, this app is a useful tool for those looking to deepen their understanding of the Catholic faith.
