When the Blessed Mother appeared to Adele Brise at Champion, Wisconsin on October 8, 1859, her message was simple, clear, and direct.
“Teach the children what they need to know for their salvation. . . Teach them their catechism, how to sign themselves with the Sign of the Cross, and how to approach the sacraments; that is what I wish you to do. Go and fear nothing. I will help you.”
And just how are we to approach the sacrament of the Holy Eucharist at Mass? The Church instructs us that we need to be in a state of grace to receive Holy Communion, that is we should not be conscious of any unconfessed mortal sin at the time of Holy Communion. Moreover, we should keep to the one hour fast from food and beverage before Communion. For the rest, in the USA, the faithful are free to receive Holy Communion standing or kneeling, on the tongue or in the hand.
But we should try to receive Our Lord with piety, devotion, hunger, and desire.
You get out of it what you put into it.
