Bíblia Almeida Século 21 is a version of the Bible created by João Ferreira de Almeida, who is also the author of the well-known book A Vida, a Gota and a Travesía. This version has been created with the purpose of offering the Holy Bible to the public, in a modern way, and also with the purpose of offering a new reading experience, which is not the case for other versions of the Bible.

In order to create this version of the Bible, which is a completely new reading experience, it was necessary to make a change in the way of reading the text, and this change was made by using a new type of text, which is the Novo acordo or the New Agreement.
