Our venerable and God-bearing Father Anastasius of Sinai (also Anastasios or Anastasius Sinaita) is a 7th century saint who left the world and everything in it. He is considered one of the Greek Fathers of the Church. St. Anastasius is commemorated on April 20 and along with his fellow ascetics each Bright Wednesday, the Synaxis of the Monastic Fathers of Sinai. Another saint called "Anastasius of Sinai" was Patriarch Anastasius I of Antioch who is also commemorated on April 20.
