Besides being the leavetaking of the Feast of the Elevation of the Cross, I saw that we’d be chanting a lot about the Great-Martyr Euphemia, and so I looked her up at the OCA Website (which is the best resource of online hagiographies I’ve found, BTW). She was persecuted, tortured and martyred in 305 AD in Chalcedon. The strength of her testimony is reflected in her troparion:

Your lamb Euphemia calls out to You, O Jesus, in a loud voice:
“I love You, my Bridegroom, and in seeking You I endure suffering.
In baptism I was crucified so that I might reign in You,
and I died so that I might live with You.
Accept me as a pure sacrifice,
for I have offered myself in love.”
Through her prayers save our souls, since You are merciful!

But she is also remembered for a miracle that occurred after her death and is commemorated on July 11. The OCA account reads:

One and a half centuries later, at a time when the Christian Church had become victorious within the Roman Empire, God deigned that Euphemia the All-Praised should again be a witness and confessor of the purity of the Orthodox teaching.

In the year 451 in the city of Chalcedon, in the very church where the glorified relics of the holy Great Martyr Euphemia rested, the sessions of the Fourth Ecumenical Council (July 16) took place. The Council was convened for determining the precise dogmatic formulae of the Orthodox Church concerning the nature of the God-Man Jesus Christ. This was necessary because of the widespread heresy of the Monophysites [”mono-physis” meaning “one nature”], who opposed the Orthodox teaching of the two natures in Jesus Christ, the Divine and the Human natures (in one Divine Person). The Monophysites falsely affirmed that in Christ was only one nature, the Divine [i.e. that Jesus is God but not man, by nature], causing discord and unrest within the Church. At the Council were present 630 representatives from all the local Christian Churches and after prolonged discussions the two sides could not come to a decisive agreement.

The holy Patriarch Anatolius of Constantinople proposed that the Council submit the decision of the Church dispute to the Holy Spirit, through His undoubted bearer St Euphemia the All-Praised, whose wonderworking relics had been discovered during the Council’s discussions. The Orthodox hierarchs and their opponents wrote down their confessions of faith on separate scrolls and sealed them with their seals. They opened the tomb of the holy Great Martyr Euphemia and placed both scrolls upon her bosom. Then, in the presence of the emperor Marcian (450-457), the participants of the Council sealed the tomb, putting on it the imperial seal and setting a guard to watch over it for three days. During these days both sides imposed upon themselves strict fast and made intense prayer.

After three days the patriarch and the emperor in the presence of the Council opened the tomb with its relics: the scroll with the Orthodox confession was held by St Euphemia in her right hand, and the scroll of the heretics lay at her feet. … After this miracle many of the hesitant accepted the Orthodox confession, while those remaining obstinant in the heresy were consigned to the Council’s condemnation and excommunication.

And so during Orthros, we also heard:

Let us all celebrate together the memory of the illustrious Euphemia. She received the formula of Orthodoxy from the Fathers; by holding on to it, she clearly demonstrated who it was that professed the true Faith.

I just thought that was interesting. Hope everyone had a good leavetaking of the Feast.
