No reference to the Book of Baruch is found in Rabbinic literature; nor is its text cited.[1][9] A fragment of the Letter of Jeremiah in Greek has been excavated amongst the Dead Sea Scrolls, but no counterpart fragments survive of the Book of Baruch.[10] There are no references to, quotations from, or allusions to the Book of Baruch in the New Testament;[4][11] although Adams proposes a general similarity between themes in the later parts of the book and some in the Pauline Epistles, particularly Galatians and 1 Corinthians.[12] The earliest evidence for the text of the Book of Baruch is in quotations in the works of early Christian Church Fathers; the earliest citation being in the Legatio pro Christianis: 9 of Athenagoras of Athens, dated 177.[4] Much the most extensive use of the Book of Baruch in patristic literature is in the Adversus Haereses: 5.35.1 (c. 180) of Irenaeus of Lyons; which draws extensively on Baruch 4:36 to 5:9.[12] Both Athenagorus and Irenaeus cite these readings as being from the Book of Jeremiah.
