I won’t attempt to give a better account than those already widely available on the Internet.
I will only encourage you to pray the Rosary and carry out the Five First Saturdays devotion in reparation to the Immaculate Heart of Mary.
Our Lady of Fatima, pray for us!
Very much worth it though.
‘My soul proclaims the greatness of the Lord
and my spirit exults in God my saviour;
because he has looked upon his lowly handmaid.
Yes, from this day forward all generations will call me blessed,
for the Almighty has done great things for me.
Holy is his name,
and his mercy reaches from age to age for those who fear him.
He has shown the power of his arm,
he has routed the proud of heart.
He has pulled down princes from their thrones and exalted the lowly.
The hungry he has filled with good things, the rich sent empty away.
He has come to the help of Israel his servant, mindful of his mercy
– according to the promise he made to our ancestors –
of his mercy to Abraham and to his descendants for ever.’
Mary, assumed into Heaven, pray for us.
Credo in unum Deum,
factorem caeli et terrae,
visibilium omnium et invisibilium,
Et in unum Dominum Iesum Christum,
Filium Dei unigenitum,
et ex Patre natum, ante omnia saecula,
Deum de Deo, lumen de Lumine,
Deum verum de Deo vero,
genitum, non factum, consubstantialem Patri:
per quem omnia facta sunt.
Qui propter nos homines et propter nostram salutem descendit de caelis.
Et incarnatus est de Spiritu Sancto
ex Maria Virgine, et homo factus est.
Crucifixus etiam pro nobis sub Pontio Pilato;
passus et sepultus est,
et resurrexit tertia die, secundem Scripturas,
et ascendit in caelum, sedet ad dexteram Patris.
Et iterum venturus est cum gloria,
iudicare vivos et mortuos,
cuius regni non erit finis.
Et in Spiritum Sanctum, Dominum et vivificantem:
qui ex Patre Filioque procedit.
Qui cum Patre et Filio simul adoratur et conglorificatur:
qui locutus est per prophetas.
Et unam, sanctam, catholicam et apostolicam Ecclesiam.
Confiteor unum baptisma in remissionem peccatorum.
Et exspecto resurrectionem mortuorum,
et vitam venturi saeculi. Amen.
It is recommended to pray to these two Saints regarding marriage.
Saint Joachim and Saint Anne, pray for us.
