"To prepare for worthy reception of this sacrament, the faithful should observe the fast required in their Church. (Cf. Code of Canon Law, canon 919) Bodily demeanor (gestures, clothing) ought to convey the respect, solemnity, and joy of this moment when Christ becomes our guest.” — Catechism of the Catholic Church, No. 1387.

Someone once asked how a priest decides the penance he gives in confession.

Most priests do not necessarily use a formula or a precise method. Sometimes it’s just the standard “three Hail Marys.” Other times the penance may be a little more involved. A lot depends on the needs of the penitent.

Blessed are you, Lord God of all creation, for through your goodness we have received the bread we offer you: fruit of the earth and work of human hands, it will become for us the bread of life.

Blessed are you, Lord God of all creation, for through your goodness we have received the wine we offer you: fruit of the vine and work of human hands. it will become our spiritual drink.

— From the Roman Missal: Preparation of the Gifts.

As Catholics, when we fast, we fast. When we feast, we feast!

The Eucharist commits us to the poor. To receive in truth the Body and Blood of Christ given up for us, we must recognize Christ in the poorest, his brethren:

‘You have tasted the Blood of the Lord, yet you do not recognize your brother, . . . You dishonor this table when you do not judge worthy of sharing your food someone judged worthy to take part in this meal . . . God freed you from all your sins and invited you here, but you have not become more merciful.’ — Catechism of the Catholic Church, No. 1397 (quote from St. John Chrysostom).
