Believers regard him as a "newly revealed" ("νεοφανής") saint, whose existence is a matter of divine revelation rather than historical proof.
St. Ephraim's name and biography, complete with exact dates and details, is said to have been revealed to a hermit nun, Makaria Desipri, in a series of divinely inspired dreams in 1950.
Following these dreams, a body believed to be that of the saint was found in the ground near the nun's hermitage, on the site of an abandoned medieval monastery on the slopes of Mount Amomon, near the today town of Nea Makri, in Attica, Greece.
On the site of his supposed life and martyrdom a Monastery of the Annunciation of Our Lady (Ιερά Μονή Ευαγγελισμού της Θεοτόκου) was later erected.
The monastery in Nea Makri, the centre of the saint's veneration and his miracle-working, is now a much-frequented place of pilgrimage attracting thousands of visitors, especially people praying for the healing of illnesses.
