Holy Martyr Cecilia and Those with Her

Reading from the Synaxarion:

Saint Cecilia was of an illustrious Roman family. On being betrothed to
Valerian, she drew him to the Faith of Christ, and he in turn drew his own
brother Tiburtius to the same. They contested in martyrdom during the
reign of Diocletian, in the year 288.

Kontakion in the Fourth Tone
In godly wise let us, the hosts of the faithful, sing hymns to her
wedded to Christ of her own will, Cecilia, whose pure heart with virtues
was adorned; for she wholly put to shame the conceit of Almacius, and
she shone bright as the sun amidst them that pursued her and then
appeared to those upon the earth as a divine staff that strengthened the
holy Faith.
