The Sacrifice of Christ is Accomplished
At the Mystical ("Last") Supper, Christ celebrates sacramentally His Sacrifice on the Cross. He offers His Holy Blood, and by calling it the blood of the New Covenant [or 'Testament']. 'He shows that He is going to die. That is why He talks about a testament, a will. And indeed He recalls the earlier Covenant [the Old Testament] because that too was ratified by blood [cf. Hebrews 9:18-21].' At the Mystical Supper, we were the past [the Old Testament], the present [the New Testament], and the future [His imminent death] coexisting in the Person of Christ.
June 24 - Nativity of Saint John the Baptist
Six months before his appearing to the Most Holy Ever-Virgin Mary in Nazareth, the Great Gabriel, Archangel of the Lord, appeared to Zacharias the High Priest in the Temple in Jerusalem. Before he revealed the miraculous conception by a virgin who has not known a man, the Archangel revealed the Wondrous conceiving by an old and barren woman.
June 22 - Hieromartyr Eusebius, Bishop of Samasota
Saint Eusebius was a major opponent of the very dangerous heresy of Arianism. When the Patriarchal throne of Antioch became vacant, Meletius was elected Patriarch. This Meletius was a shining light in the Church and deserved the great eulogy given by Saint John Chrysostom at his death. But the Arian heretics soon drove Meletius from Antioch. When Constantius, Constantine's evil son, died, he was followed by another heretic Julian the Apostate, a man even worse than he, as ruler of the Empire.
Looking Toward Heaven
True Christians live in this world as travelers, pilgrims, and sojourners, and they look ever toward their heavenly homeland with faith and with the eyes of the soul, and they strive to reach it. You should also be a pilgrim and sojourner in this world and constantly look toward that homeland and strive to obtain it, and so the world with its enticements and lusts will become abhorrent to you. Whoever seeks eternal blessedness and desires it and strives to reach it will despise everything temporal, lest while seeking the temporal he e deprived of the eternal.
The Mysteries (Mysteria) [Sacraments] of the Orthodox Church
The inward life of the Church is mystical (or sacramental). The word "mysteries" (Greek: mysteria) is the term in the Orthodox East: "sacraments" (Latin: sacramenta), the term used in the Latin West (Roman Catholic). Orthodox Christians prefer to use the Greek term. The adjectival form "mystical," used in the Orthodox Church, has of course a rather different and more inward connotation that the Western adjective "sacramental" which refers more specifically to the outward rites of the Mysteries. It does not at all coincide with the history of the Church, which shows us only the outward facts of the Church's existence, and especially its coming into conflict with the life of the world and the passions of the world. The inward life of the Church is the mystical cooperation of Christ as the Head, with the Church as His Body, in the Holy Spirit, by means of all mutually strengthening ties: "This is a great mystery: but I speak concerning Christ and the church," instructs the holy Apostle (Ephesians 5:32).
Orthodox Christian Worship: "Heaven on Earth"
"Then I saw another Angel flying in the midst of heaven, having the everlasting gospel to preach to those who dwell on the earth--to every nation, tribe, tongue, and people--saying with a loud voice, Fear God and give glory to Him, for the hour of His judgment has come; and worship Him Who made heaven and earth, the sea and springs of water" (Revelation 14:6-7).
