Aphthartodocetism is the teaching associated with Julian of Halicarnassus that Christ’s body was incorruptible from the moment of union, rather than only after the Resurrection.[^1]

## Definition and terminology

Aphthartodocetism is associated with Julian, bishop of Halicarnassus, who taught that Christ’s body was free from corruption from the moment of union, rather than becoming incorruptible only at the Resurrection. His followers were known to their opponents as Julianists, Aphthartodocetae, or Phantasiastae. The designation Aphthartodocetae referred to their teaching of bodily incorruptibility, expressed by the term *aphtharsia*.[^1]

## Teaching concerning Christ’s body

Julian maintained that Christ was free from the corruption affecting humanity in its fallen condition. He understood Christ, as the Son of Man, to be consubstantial with Adam before the Fall rather than with humanity in its present fallen state.[^2] Another supplied account describes Julian’s followers as teaching both the incorruptibility and immortality of Jesus’ body from the first moment of the Incarnation.[^3]

The teaching prompted comparisons with earlier Docetism, which regarded Christ’s humanity, especially his body, as apparent rather than real. The source presents this as an analogy suggested by Julian’s doctrine, rather than simply identifying his stated teaching with Docetism.[^2]

## Opposition and related divisions

Opposition to Julian came from other opponents of the Council of Chalcedon, notably Severus, patriarch of Antioch. Julian wrote four works against Severus; fragments survive in Syriac and Greek, together with some recovered letters.[^4]

A related division in Alexandria set the Theodosians, followers of Theodosius I and adherents of Severus, against the followers of Gaianus. The former upheld the corruptibility of Christ’s body, while the latter, also called Phantasiastae, upheld its incorruptibility. The account describes violent hostility between these groups and records that Cyrus of Phasis effected a union of the Theodosians and Gaianites on 3 June 633.[^5]
