Peter, Archbishop of Alexandria

Reading from the Synaxarion:

Saint Peter illustriously occupied the throne of Alexandria for twelve
years, and, as Eusebius says, "was a divine example of a bishop on
account of the excellence of his life and his study of the sacred
Scriptures" (see Eusebius, Eccl. Hist., Book VII, 3 2; Book VIII 11, 13; and
Book IX, 6). He excommunicated Arius for his sympathy with the
Meletian schism. When Arius learned that Saint Peter had been imprisoned,
he sent many priests and deacons to him, asking that he receive him
back into the communion of the Church before his martyrdom. When the
ambassadors of Arius, who had not, like Saint Peter, perceived the ruin he
would engender, were astonished at the vehemence with which Saint Peter
refused to receive Arius again, he revealed to them a dread vision he had
seen, in which the Master Christ had appeared to him as a child wearing
a garment torn from head to foot. When Saint Peter asked the Lord
who rent His garment, the Lord answered that it was Arius, and that
he must not be received back into communion. The holy hieromartyr
Peter was beheaded during the reign of Maximinus in the year 312; he is
called the "Seal of the Martyrs," because he was the last Bishop of
Alexandria to suffer martyrdom under the pagan Emperors. His successors to
the throne of Alexandria, Saints Alexander and Athanasius the Great,
brought to final victory the battle against Arius' heresy which Saint
Peter had begun.

Peter, Alexis, Jonah, Hermogenes and Tikhon, Metropolitans of Moscow

Reading from the Synaxarion:

The feast of the Hierarchs of Moscow was established during the reign
of Tsar Theodore Ioannovich and Patriarch Job in the year 1596.
Their individual feasts are: Saint Peter (+1326), December 21, and
August 24, translation of holy relics; Saint Alexis (+14th cent.),
February 12, and May 20, recovery of holy relics; Saint Jonas (+1461),
March 31 and June 15, with the recovery of his holy relics celebrated
on May 27. In 1875, at the proposal of Metropolitan Innocent of
Moscow, to this feast was joined the commemoration of Saint Philip of
Moscow (+1569), whose feast is kept on January 9, and the recovery of
his holy relics on July 3. In more recent times, the holy Patriarchs
Hermogenes (+1612) and Tikhon (+1925) have been added to the Synaxis. Saint
Hermogenes, who was starved to death by the Poles, is also celebrated on
February 17 and May 12, and Saint Tikhon, a confessor under the atheist
yoke, on March 25. the Menaion service itself makes reference only to
Saints Peter, Alexis, Jonas, and Philip.

Ye lived piously among bishops; ye led the peoples to the knowledge
of God, and ye pleased God well. Wherefore, ye were glorified by
Him with incorruption and miracles, as disciples of the grace of God.
