First Friday Devotion Promises
Jesus gave the following promises to Saint Margaret Mary for souls and devoted to his most Sacred Heart:
1. I will give them all the graces necessary in their state of life.
2. I will establish peace in their homes
3. I will confort them in their afflictions
4. I will be their secure refuge in life and above all in death.
5. I will bestow abundant blessings on all their undertakings
6. Sinners shall find in My heart the source and infinite ocean of mercy.
7. Tepid souls shall become fervent.
8. Fervent souls shall quickly mount to high perfection.
9. I will bless every place where a picture of My heart shall be exposed
and honored.
10. I will give to priests the gift of touching the most hardened hearts.
11. Those who shall promote this devotion shall have their names written in My Heart, never to be blotted out.
12. I promise you, in the excessive mercy of my heart that my all-powerfull love will grant to all those who receive Holy Communion on the first Friday for 9 consecutive months the grace of final repentance: they shall not die in My Disgrace nor without receiving the sacraments; My Divine Heart shall be their safe refuge in that last moment.
Why go to Daily Mass?
Every Mass is worth as much as the sacrifice of Our Lord's life, sufferings, and death.
Holy Mass is the world's most powerful atonement for your sins.
At the hour of death the holy Masses you have heard devoutly will be your greatest consolation.
Every Mass will go with you to judgment and plead for pardon.
At Mass, you can diminish more or less temporal punishment due to your sins, according to your fervor.
Assisting devoutly at Holy Mass, you render to the sacred humanity of Our Lord the greatest homage.
He forgives the venial sins which you have not confessed. The power of Satan over you is diminished. He supplies for many of your negligence and omissions.
You are preserved from dangers and misfortunes which otherwise might have befallen you.
You shorten your Purgatory.
Every Mass wins for you a higher degree of glory in Heaven.
You receive the priest's blessing which Our Lord ratifies in Heaven.
You kneel amidst a multitude of holy angels, who are present at the adorable Sacrifice with reverential awe.
You are blessed in your temporal goods and affairs.
By piously hearing Holy Mass you afford the Souls in Purgatory the greatest possible relief.
One Mass heard during life will be of more benefit to you than many heard for you after your death.
