Daniel 7:9-10, 13-14 or Revelation 12:7-12ab
USCCB Podcast of the Readings:
War broke out in heaven;
Michael and his angels battled against the dragon.
The dragon and its angels fought back,
but they did not prevail
and there was no longer any place for them in heaven.
The huge dragon, the ancient serpent,
who is called the Devil and Satan,
who deceived the whole world,
was thrown down to earth,
and its angels were thrown down with it.
Then I heard a loud voice in heaven say:
“Now have salvation and power come,
and the Kingdom of our God
and the authority of his Anointed.
For the accuser of our brothers is cast out,
who accuses them before our God day and night.
They conquered him by the Blood of the Lamb
and by the word of their testimony;
love for life did not deter them from death.
Therefore, rejoice, you heavens,
and you who dwell in them.”
The Salvation has already in the Air ,the power and anointing comes from the blood of the Lamb and the Word of the Testimony.
Every Baptised /Transformed or Born again Christian has been cleansed by the blood of Christ and becomes a witness to his Word despite of the challenges of this World.The Works of the Evil one do not affect him or her because the Devil does not have any authority over them because Christ has defeated Satan and his Angels. The Arch Angels are the Heavenly Soldiers who part in the Spiritual Battle against the Evil one .
The Arch Angels were the Witnesses of the Victory , invoking them or respecting them , recalls the Victory of Christ on the Cross and powerful resurrection. The Arch Angels are most powerful Spiritual Beings who are the hands of the Almighty.
Why we have to invoke Arch Angels ?The Salvation plan of Christ involves Heavenly Being, Holy Men and Women and the Holy Trinity , it is a team work very strategically and mysteriously conducted by Christ. Jesus Christ was the Head and captain of the plan but the teamwork had Angels as their front line Spiritual Warriors and Helpers. The Spiritual battle happens every day of a faithful and the power of the Salvation is required to fight the Evil temptations of this World. Angels are the medium of the grace to source out from throne of the Almighty. Praying to Angels to protect us is praying to the Almighty himself because the Angels are the hands of God himself. The Heavenly body is one including saints and the body of Christ the Church the believers of Christ on this Earth. Every believer becomes part of Heaven while living on this Earth through the power of Salvation. The Angels are like elder Heavenly beings who help us like our elder siblings in the family.So we never fail to seek the help of our elderly Beings of Christ specialy while we are in trouble and need help .
