The Orthodox Church commemorates several religious figures on September 7, including the 3rd-century martyr Saint Soson and the 9th-century Byzantine hymnographer Saint Cassia (also known as Kassiani).

Saint Cassia is recognized for her significant contributions to Byzantine ecclesiastical poetry and music, particularly her liturgical works such as the hymn ‘Kyrie, η εν πολλαίς αμαρτίαις περιπεσούσα γυνή’. Historical tradition notes her intellect and a famous dialogue with Emperor Theophilus during the Iconoclasm era. She remains one of the few female creators from the Byzantine period whose works are preserved under her own name. 

Saint Soson is remembered as a shepherd from Lycaonia who was executed for his faith after distributing proceeds from the sale of a golden idol to the poor.
