Leo the Great, Pope of Rome Reading from the Synaxarion: According to some, this Saint was born in Rome, but according to others in Tyrrenia (Tuscany), and was consecrated to the archiepiscopal throne of Rome in 440. In 448, when Saint Flavian, Archbishop of Constantinople, summoned Eutyches, an archimandrite in Constantinople, to give account for his teaching that there was only one nature in Christ after the Incarnation, Eutyches appealed to Saint Leo in Rome. After Saint Leo had carefully examined Eutyches's teachings, he wrote an epistle to Saint Flavian, setting forth the Orthodox teaching of the person of Christ, and His two natures, and also counseling Flavian that, should Eutyches sincerely repent of his error, he should be received back with all good will. At the Council held in Ephesus in 449, which was presided over by Dioscorus, Patriarch of Alexandria (and which Saint Leo, in a letter to the holy Empress Pulcheria in 451, was the first to call "The Robber Council"), Dioscorus, having military might behind him, did not allow Saint Leo's epistle to Flavian to be read, although repeatedly asked to do so; even before the Robber Council was held, Dioscorus had uncanonically received the unrepentant Eutyches back into communion. Because Saint Leo had many cares in Rome owing to the wars of Attila the Hun and other barbarians, in 451 he sent four delegates to the Fourth Ecumenical Council, where 630 Fathers gathered in Chalcedon during the reign of Marcian, to condemn the teachings of Eutyches and those who supported him. Saint Leo's epistle to Flavian was read at the Fourth Council, and was confirmed by the Holy Fathers as the Orthodox teaching on the incarnate person of our Lord; it is also called the "Tome of Leo." The Saint wrote many works in Latin; he reposed in 461. See also Saint Anatolius, July 3. Apolytikion in the Fourth Tone The truth of things hath revealed thee to thy flock as a rule of faith, an icon of meekness, and a teacher of temperance; for this cause, thou hast achieved the heights by humility, riches by poverty. O Father and Hierarch Leo, intercede with Christ God that our souls be saved. Kontakion in the Third Tone Seated on the priestly throne, O great and glorious Leo, with the Holy Trinity's inspired and God-given doctrines thou didst stop the gaping mouths of spiritual lions and didst shine upon thy flock the light of God-knowledge, and art glorified now as a divine initiate of the sublime grace of God.

Sylvester, Pope of Rome

Reading from the Synaxarion:

Saint Sylvester was a native of Rome. Because of his exceeding virtue,
he succeeded Saint Miltiades as Pope in 314. Since he himself was
unable to be present at the First Ecumenical Council in 325, he sent
delegates of his own Roman clergy to represent him in Nicaea. He reposed in
the year 325.

Apolytikion in the Fourth Tone
The truth of things hath revealed thee to thy flock as a rule of
faith, an icon of meekness, and a teacher of temperance; for this cause,
thou hast achieved the heights by humility, riches by poverty. O
Father and Hierarch Sylvester, intercede with Christ God that our souls
be saved.

Kontakion in the Fourth Tone
As a companion of the holy ascetics, thou O God-bearer, hast been
worthily shown forth as a true priest of priests before our King and God.
Wherefore, thou rejoicest now with the choirs of the Angels, filled with
gladness and delight in the Heavens, O Father. Renowned Sylvester, famed
shepherd of Rome, save them that honour with love thy memorial.

Our Holy Father Clement, Pope of Rome

Reading from the Synaxarion:

Saint Clement was instructed in the Faith of Christ by the Apostle
Peter. He became Bishop of Rome in the year 91, the third after the
death of the Apostles. He died as a martyr about the year 100 during
the reign of Trajan.

Apolytikion in the Fourth Tone
O God of our Fathers, ever dealing with us according to Thy
gentleness: take not Thy mercy from us, but by their entreaties guide our
life in peace.

Kontakion in the Fourth Tone
O divine unshakeable towers of Christ's Church, pillars of true
piety who are most mighty and divine: Clement and Peter, ye
all-acclaimed, by your entreaties, protect and guard all of us.
