“[T]he Church has always looked on catechesis as a sacred duty and an inalienable right… [I]t is certainly a duty springing from a command given by the Lord and resting above all on those who in the New Covenant receive the call to the ministry of being pastors… [O]ne can likewise speak of a right: from the theological point of view every baptized person… has the right to receive from the Church instruction and education enabling him or her to enter on a truly Christian life; and from the viewpoint of human rights, every human being has the right to seek religious truth and adhere to it freely…

The specific character of catechesis, as distinct from the initial conversion-bringing proclamation of the Gospel, has the twofold objective of maturing the initial faith and of educating the true disciple of Christ by means of a deeper and more systematic knowledge of the person and the message of our Lord Jesus Christ… It is true that being a Christian means saying ” yes ” to Jesus Christ, but let us remember that this “yes” has two levels: it consists in surrendering to the word of God and relying on it, but it also means, at a later stage, endeavoring to know better and better the profound meaning of this word.

“Authentic catechesis is always an orderly and systematic initiation into the revelation that God has given of himself to humanity in Christ Jesus, a revelation stored in the depths of the Church’s memory and in Sacred Scripture, and constantly communicated from one generation to the next by a living active traditio…” (Saint John Paul the Great, Apostolic Exhortation “Catechesi Tradendae”)

“[W]hen the men were come to him, they said: John, the Baptist, hath sent us to thee, saying: Art thou he who is to come: or expect we another? (And in that same hour, he cured many of their diseases, and sores, and evil spirits, and to many that were blind, he gave sight.) And, answering, he said to them: Go and relate to John what you have heard and seen: That the blind see, the lame walk, the lepers are made clean, the deaf hear, the dead rise again, to the poor the gospel is preached:

“And… he began to speak to the multitudes concerning John:… But what went you out to see? a prophet? Yea, I say to you, and more than a prophet. This is he of whom it is written: Behold I send my angel before thy face, who shall prepare thy way before thee. For I say to you: Amongst those that are born of women, there is not a greater prophet than John, the Baptist: but he who is lesser in the kingdom of God, is greater than he…

“And the Lord said: Whereunto then shall I liken the men of this generation?… They are like to children sitting in the market-place… saying: We have piped to you, and you have not danced: we have mourned, and you have not wept. For John, the Baptist, came, neither eating bread, nor drinking wine, and you say: He hath a devil. The Son of man is come eating and drinking, and you say: Behold a man that is a glutton and a drinker of wine, a friend of publicans and sinners. And wisdom is justified by all her children.”

“The chalice of benediction which we bless, is it not the communion of the blood of Christ? And the bread which we break, is it not the partaking of the body of the Lord? For we being many, are one bread, one body, all who partake of one bread…

“For as often as you shall eat this bread, and drink the chalice, you shall shew the death of the Lord until he come.

“Wherefore, whosoever shall eat this bread, or drink the chalice of the Lord unworthily, shall be guilty of the body and of the blood of the Lord… not discerning the body of the Lord.
