The Epistle to the Laodiceans is a possible writing of Paul the Apostle, the original existence of which is inferred from an instruction in the Epistle to the Colossians that the congregation should send their letter to the believing community in Laodicea, and likewise obtain a copy of the letter "from Laodicea" (Greek: ἐκ Λαοδικείας, ek Laodikeas).
An additional complication is that many scholars do not believe that Colossians was itself written by Paul, in which case the indicated letter might itself not be Pauline even if it existed.
[3] The sole version that survived is a Latin Epistola ad Laodicenses ("Epistle to the Laodiceans"), first witnessed in Codex Fuldensis.
Despite this, it was part of medieval Bibles in the Western, Latin church for centuries, with it only becoming clearly non-canonical after it was rejected by both the Protestant reformers and the Catholic Council of Trent in the early modern era.
Paul apparently dictated all his epistles through a secretary (or amanuensis), but wrote the final few paragraphs of each letter by his own hand.
The Epistle to the Colossians, which is traditionally attributed to Paul, includes a seeming reference to a presumably Pauline letter in the possession of the church at Laodicea.
[10] Some scholars have suggested that it refers to the canonical Epistle to the Ephesians, contending that it was a circular letter (an encyclical) to be read to many churches in the Laodicean area.
[9][13][14] ...there is current also (an epistle) to the Laodiceans, another to the Alexandrians, forged in Paul's name for the sect of Marcion, and several others, which cannot be received in the catholic Church; for it will not do to mix gall with honey.
It is mentioned by various writers from the fourth century onwards, notably by Pope Gregory the Great; the oldest known copy of this epistle is in the Fulda manuscript written for Victor of Capua in 546.
The text was almost unanimously considered pseudepigraphal when the Christian Biblical canon was decided upon, and does not appear in any Greek copies of the Bible at all, nor is it known in Syriac or other versions.
[21] The apocryphal epistle is generally considered a transparent attempt to supply this supposed lost sacred document.
