The Second Epistle of Clement (Ancient Greek: Κλήμεντος πρὸς Κορινθίους Klēmentos pros Korinthious "Clement to Corinthians") often referred to as 2 Clement or Second Clement, is an early Christian writing. 2 Clement was not accepted in the canonical New Testament, but was included in the Apostolic Fathers collection.
2 Clement was traditionally believed to have been epistle to the Christian Church in Corinth written by Clement of Rome sometime in the late 1st century. However, 4th-century bishop Eusebius, in his historical work, says that there is one "extant an epistle of this Clement", so doubts about this work belonging to Clement of Rome are not new. Modern scholars believe that Second Clement is actually a sermon written around 95-140 CE by an anonymous author, one who was neither the author of 1 Clement nor Clement of Rome. Nonetheless, scholars still generally refer to the work by its traditional name "Second Clement".
2 Clement appears to be a transcript of a homily or sermon that was originally delivered orally at a Christian worship service. For example, in ch. 19 the speaker announces that he will read aloud from scripture – something one would only expect to find in a transcript of an oral sermon. Similarly, whereas an epistle would typically begin by introducing the sender and recipient, 2 Clement starts with by addressing "Brethren", and then proceeding directly to the sermon. If it is a sermon, 2 Clement would be the earliest surviving Christian sermon (aside from those found in the New Testament).
Like many early Christian texts, 2 Clement was written in Greek, the common language of the Hellenized Mediterranean area.
The earliest external reference to 2 Clement is found in Eusebius's Ecclesiastical History written in the early 4th century:
But it must be observed also that there is said to be a second epistle of Clement. But we do not know that this is recognized like the former, for we do not find that the ancients have made any use of it. And certain men have lately brought forward other wordy and lengthy writings under his name, containing dialogues of Peter and Apion. But no mention has been made of these by the ancients; for they do not even preserve the pure stamp of apostolic orthodoxy.
