The Acts of the Apostles is a genre of early Christian literature, recounting the lives and works of the apostles of Jesus. The Acts are important for many reasons, one of them being the concept of apostolic succession. They also provide insight into the valuation of "missionary activities among the exotic races," since some of them feature missionary work done among, for instance, the Cynocephaly.

The Acts of John refers to a collection of stories about John the Apostle that began circulating in written form as early as the 2nd-century AD. Translations of the Acts of John in modern languages have been reconstructed by scholars from a number of manuscripts of later date. The Acts of John are generally classified as New Testament apocrypha.
