Saints and feasts of April 20

Theodore Trichinas
Venerable, Θεόδωρος
St. Theodore Trichinas was born in Constantinople and embraced the monastic life in a monastery of the countryside. He is called Trichinas, the hair-shirt wearer, because his only garment throughout his long ascetic struggle was a rough covering of hair, worn in every season as he mortified the flesh through fasting, vigil, and cold.
Zacchaeus the Apostle
Apostle, Ζακχαίος ο Απόστολος
Zacchaeus was the chief tax collector of Jericho who, being short of stature, climbed a sycamore tree to see Jesus and was called down to receive Him in his house, where he promised to restore fourfold all he had taken unjustly.
Athanasios of Meteora
Venerable, Αθανάσιος ο Μετεωρίτης
Athanasios was born in Hypate in the fourteenth century and became a monk on Mount Athos. Fleeing pirate raids, he came to the rocks of Meteora in Thessaly, where he climbed the great pillar of stone and founded the Monastery of the Transfiguration, the Great Meteoron.

John of the Old Lavra
Venerable, Ιωάννης ο Παλαιολαυρίτης

Joasaph of Meteora
Venerable, Ιωάσαφ ο Μετεωρίτης
