Gurias, Samonas, and Avivos, Martyrs and Confessors of Edessa

Reading from the Synaxarion:

Of these most illustrious Martyrs of the city of Edessa in Syria,
Guria and Shamuna contested during the reign of Diocletian, in 288;
after many tortures, they were cast into prison, then beheaded. Saint
Habib, a deacon, contested in the days of Licinius, in the year 316, and
was burned alive; he was buried with Saints Guria and Shamuna. The
three have one common feast, and it is always together that they are
portrayed in icons and invoked by the faithful.On account of a renowned
miracle they worked, they are invoked for help in marital difficulties. A
certain Goth had come with the Roman army to Edessa and was quartered in
the house of a pious widow named Sophia. The Goth asked Sophia for
the hand of her daughter, Euphemia; after resisting for a long time,
Sophia at last agreed. When it was time for the army to return home,
Sophia made the Goth vow by the power in the holy Martyrs Shamuna,
Guria, and Habib, to keep Euphemia as the apple of his eye. As he was
nearing his home, however, the treacherous man revealed to Euphemia that
he already had a wife. Euphemia was compelled to serve the Goths
wife, who dealt with her mercilessly. After extreme sufferings, which
included being sealed alive in a tomb and left there to die, Euphemia was
miraculously conveyed to Edessa, to the very shrine of the holy Martyrs whose
surety they had taken, and was reunited with her mother through their
holy prayers.

Apolytikion in the Plagal of the Fourth Tone
Since Thou hast given us the miracles of Thy holy Martyrs as an
invincible battlement, by their entreaties, scatter the counsels of the
heathen, O Christ our God, and strengthen the faith of Orthodox
Christians, since Thou alone art good and the Friend of man.

Kontakion in the Second Tone
O yoke-mate of Paul, together with him, thou didst preach the
tidings to us of saving grace bestowed of God, O Apostle Titus, blest and
elect revealer of mysteries; for which cause we cry out to thee: Cease
not to entreat Christ God for all of us.
