The Twelve Promises
The promises Christ made to St. Margaret Mary Alacoque in the seventeenth century, for those who honor His Sacred Heart.
In a series of revelations to St. Margaret Mary at the convent of Paray-le-Monial between 1673 and 1675, Our Lord made twelve specific promises to those who would honor and propagate the devotion to His Sacred Heart. The list below has been transmitted through the centuries in various forms; the wording given here is the traditional summary.
The twelfth promise — the Great Promise — concerning the grace of final repentance for those who receive Holy Communion on the first Friday of nine consecutive months, is perhaps the most famous; but the other eleven are no less real, no less promised, and no less binding upon the merciful Heart that pledged them.
I will give them all the graces necessary in their state of life.
I will establish peace in their families.
I will console them in all their troubles.
They shall find in My Heart an assured refuge during life, and especially at the hour of their death.
I will pour abundant blessings upon all their undertakings.
Sinners shall find in My Heart the source and infinite ocean of mercy.
Tepid souls shall become fervent.
Fervent souls shall rise speedily to great perfection.
I will bless the homes in which an image of My Heart shall be exposed and honored.
I will give to priests the power to touch the most hardened hearts.
Those who propagate this devotion shall have their names written in My Heart, never to be effaced.
I promise thee, in the excess of the mercy of My Heart, that Its all-powerful love will grant to all those who shall receive Communion on the first Friday of nine consecutive months, the grace of final repentance: they shall not die in My disgrace, nor without receiving the Sacraments; My Heart shall be their assured refuge at that last hour.
A word on how promises like these work
These are not magic incantations. They are the pledges of a Heart that has bound Itself by love. The conditions are presumed throughout: the soul that approaches must be in good faith, must intend honestly the things the devotion asks (love, reparation, fidelity), and must approach the sacraments in a state of grace. With those conditions met, the promises stand.
