Christophany

A Christophany is an appearance or non-physical manifestation of Jesus. Traditionally the term refers to visions of Christ after his ascension, such as the bright light of the conversion of Paul the Apostle.

Also, following the example of Justin Martyr, who identified the Angel of the Lord with the Logos, some appearances of angels in the Old Testament are also identified by some Christians as preincarnate appearances of Christ.
