"1 Esdras" is a deuterocanonical book accepted by all Orthodox Christians, but rejected as apocryphal by most mainstream "Orthodox" Jews, Catholics, and most Protestants. In large part it parallels the action of Ezra-Nehemiah, and the Books of Chronicles, with some sections being translations of those books.

The book was widely quoted by early Christian authors and it found a place in Origen's Hexapla. It was not included in early canons of the Western Church, and Jerome relegated it to an appendix of the New Testament in the Vulgate "lest it perish entirely". However, the use of the book continued in the Eastern Church, and it remains a part of the Orthodox canon.

"2 Esdras" (sometimes also referred to as Ezra/Shealtiel   ((or the Apocalypse of Ezra, which is also the name of a different but interdependant work))   is a Jewish apocalypse that some many scholars purport to be written toward the end of the first century AD. It is not accepted as scriptural by most Christians, who list it among the Apocrypha. However the Ethiopian and Russian Orthodox churches consider it canonical, and it was often cited by the Fathers of the Church.

The book is considered one of the gems of Jewish apocalyptic literature. While it was not received into European Christian canons, it is regarded as Scripture in the Ethiopian Orthodox Church as well as in the Russian Orthodox Church, and it was also widely cited by early Fathers of the Church, particularly Ambrose of Milan. The introitus of the traditional Requiem in the Catholic Church is taken from chapter 2: "Eternal rest grant unto them, O Lord, and let perpetual light shine upon them." Several other liturgical prayers are taken from the book. Jerome placed the book in the appendix of the New Testament in the Vulgate, "lest it perish entirely".






"The Vision of Ezra" is an ancient apocryphal text, claiming to have been written by the biblical Ezra. The earliest surviving manuscripts, composed in latin, date to the 11th Century AD, though textual peculiarities strongly suggest that the text was originally written in Greek. Like the Apocalypse of Ezra, the work is clearly Christian, and features several apostles being seen in heaven. However, the text is significantly shorter than the Apocalypse.

"The Apocalypse of Ezra" is the name of an apocryphal work claiming to have been written by the biblical Ezra, but generally regarded as having been written vastly later. Dating the work is midly controversial and there is a very wide range of potential dates, ranging from the 2nd century AD at the earliest to the 9th century AD at the latest. The text has a strong dependance on 2 Esdras, an earlier apocryphal work also attributed to Ezra.
