Leo the Great
Hierarch, Λέων ο Μέγας
St. Leo the Great was Pope of Rome in the fifth century, one of the great fathers of the undivided Church. His celebrated Tome, read at the Fourth Ecumenical Council at Chalcedon in 451, confessed with clarity that Christ is one Person in two natures, true God and true man, and the fathers of the council received it as the voice of Peter.
Leo and Paregorios of Patara
Martyr, Λέων και Παρηγόριος
Sts. Leo and Paregorios were close friends in Patara of Lycia. Paregorios was arrested first and martyred after many tortures. Leo, weeping at the place of his friend's death, was moved to smash the lamps of a pagan temple and openly confess Christ.

Hierarch, Αγαπητός Συνάου
St. Agapitos was born in Cappadocia and became a monk in his youth, famed for his asceticism and his miracles. Forced into military service under Licinius, he was wounded for his faith, then released and ordained; the Emperor Constantine later made him Bishop of Synnada.
