"The glorious company of the apostles praise Thee.
The goodly fellowship of the prophets praise Thee.
The white-robed army of martyrs praise Thee.
All Thy saints and elect with one voice do acknowledge Thee,
O Blessed Trinity, one God!"

Origin of All Saint's Day as a feast of the ChurchWhat makes this feast so important that the Church celebrates both the night before All Saints and the day after it?The Church has always honored those early witnesses to the Christian faith who have died in the Lord. (The Greek word for "witness" is martyr.) During the first three hundred years Christians were serverly persecuted, often suffering torture and bloody death -- because they were faithful . They refused to deny Christ, even when this denial might have saved their own lives, or the lives of their children and families.
The early history of the Church is filled with stories of the heroic faith of these of witnesses to Christ's truth. The stories of these saints -- these baptized Christians of all ages and all states in life, whose fidelity and courage led to their sanctity or holiness -- have provided models for every other Christian throughout history.
Many of those especially holy people whose names and stories were known, the Church later canonized (that is, the Church formally recognized that the life of that person was without any doubt holy, or sanctified -- a "saint" who is an example for us.) The Church's calendar contains many saint's days, which Catholics observe at Mass -- some with special festivities.
But there were thousands and thousands of early Christian martyrs, the majority of whose names are known only to God -- and throughout the history of the Church there have been countless others who really are saints, who are with God in heaven, even if their names are not on the list of canonized saints.
In order to honor the memory -- and our own debt -- to these unnamed saints, and to recall their example, the Church dedicated a special feast day -- a sort of "memorial day" -- so that all living Christians would celebrate at a special Mass the lives and witness of those "who have died and gone before us into the presence of the Lord".
This feast that we know as All Saint's Day originated as a feast of All Martyrs, sometime in the 4th century. At first it was celebrated on the first Sunday after Pentecost. It came to be observed on May 13 when Pope St. Boniface IV (608-615) restored and rebuilt for use as a Christian church an ancient Roman temple which pagan Rome had dedicated to "all gods", the Pantheon. The pope re-buried the bones of many martyrs there, and dedicated this Church to the Mother of God and all the Holy Martyrs on May 13, 610.
About a hundred years later, Pope Gregory III (731-741) consecrated a new chapel in the basilica of St. Peter to all saints (not just to the martyrs) on November 1, and he fixed the anniversary of this dedication as the date of the feast.
A century after that, Pope Gregory IV (827-844) extended the celebration of All Saints to November 1 for the entire Church.
The vigil of this important feast, All Saint's Eve, Hallowe'en, was apparently observed as early as the feast itself.
Ever since then -- for more than a millennium -- the entire Church has celebrated the feast of All Saints on November 1st, and, of course, Hallowe'en on October 31.
It is a principal feast of the Catholic Church. It is a holy day of obligation, which means that all Catholics are to attend Mass on that day.

First Reading: Revelation 7:2-4, 9-14
I, John, saw another angel ascend from the rising of the sun, with the seal of the living God, and he called with a loud voice to the four angels who had been given power to harm earth and sea, saying, "Do not harm the earth or the sea or the trees, till we have sealed the servants of our God upon their foreheads." And I heard the number of the sealed, a hundred and forty-four thousand sealed, out of every tribe of the sons of Israel.
After this I looked, and behold, a great multitude which no man could number, from every nation, from all tribes and peoples and tongues, standing before the throne and before the Lamb, clothed in white robes, with palm branches in their hands, and crying out with a loud voice, "Salvation belongs to our God who sits upon the throne, and to the Lamb!" And all the angels stood round the throne and round the elders and the four living creatures, and they fell on their faces before the throne and worshiped God, saying, "Amen! Blessing and glory and wisdom and thanksgiving and honor and power and might be to our God for ever and ever! Amen."
Then one of the elders addressed me, saying, "Who are these, clothed in white robes, and whence have they come?" I said to him, "Sir, you know." And he said to me, "These are they who have come out of the great tribulation; they have washed their robes and made them white in the blood of the Lamb.
Second Reading: 1 John 3:1-3
See what love the Father has given us, that we should be called children of God; and so we are. The reason why the world does not know us is that it did not know Him. Beloved, we are God's children now; it does not yet appear what we shall be, but we know that when He appears we shall be like Him, for we shall see Him as He is. And every one who thus hopes in Him purifies Himself as He is pure.
Gospel Reading:
When Jesus saw the crowds, He went up on the mountain, and when He sat down His disciples came to Him. And He opened His mouth and taught them, saying: "Blessed are the poor in spirit, for theirs is the kingdom of heaven. "Blessed are those who mourn, for they shall be comforted. "Blessed are the meek, for they shall inherit the earth. "Blessed are those who hunger and thirst for righteousness, for they shall be satisfied. "Blessed are the merciful, for they shall obtain mercy. "Blessed are the pure in heart, for they shall see God. "Blessed are the peacemakers, for they shall be called sons of God. "Blessed are those who are persecuted for righteousness' sake, for theirs is the kingdom of heaven.
"Blessed are you when men revile you and persecute you and utter all kinds of evil against you falsely on My account. Rejoice and be glad, for your reward is great in heaven.

During the year the Church celebrates one by one the feasts of the saints. Today she joins them all in one festival. In addition to those whose names she knows, she recalls in a magnificent vision all the others "of all nations and tribes standing before the throne and in sight of the Lamb, clothed with white robes, and palms in their hands, proclaiming Him who redeemed them in His Blood."
