What is the Apocryphal?
Apocrypha
The wider Christian canon accepted by Augustine became the more established canon in the western Church[34] after being promulgated for use in the Easter Letter of Athanasius (circa 372 A.D.), the Synod of Rome (382 A.D., but its Decretum Gelasianum is generally considered to be a much later addition[35] )  and the local councils of Carthage and Hippo in north Africa (391 and 393 A.D). Athanasius called canonical all books of the Hebrew Bible including Baruch, while excluding Esther. He adds that "there are certain books which the Fathers had appointed to be read to catechumens for edification and instruction; these are the Wisdom of Solomon, the Wisdom of Sirach (Ecclesiasticus), Esther, Judith, Tobias, the Didache, or Doctrine of the Apostles, and the Shepherd of Hermas. All others are apocrypha and the inventions of heretics (Festal Epistle for 367)".[36]
