From Ecclesia de Eucharistia:
10. In various parts of the Church abuses have occurred, leading to confusion with regard to sound faith and Catholic doctrine concerning this wonderful sacrament. At times one encounters an extremely reductive understanding of the Eucharistic mystery. Stripped of its sacrificial meaning, it is celebrated as if it were simply a fraternal banquet. Furthermore, the necessity of the ministerial priesthood, grounded in apostolic succession, is at times obscured and the sacramental nature of the Eucharist is reduced to its mere effectiveness as a form of proclamation. This has led here and there to ecumenical initiatives which, albeit well-intentioned, indulge in Eucharistic practices contrary to the discipline by which the Church expresses her faith. How can we not express profound grief at all this? The Eucharist is too great a gift to tolerate ambiguity and depreciation.
13. By virtue of its close relationship to the sacrifice of Golgotha, the Eucharist is a sacrifice in the strict sense, and not only in a general way, as if it were simply a matter of Christ's offering himself to the faithful as their spiritual food. The gift of his love and obedience to the point of giving his life (cf. Jn 10:17-18) is in the first place a gift to his Father. Certainly it is a gift given for our sake, and indeed that of all humanity (cf. Mt 26:28; Mk 14:24; Lk 22:20; Jn 10:15), yet it is first and foremost a gift to the Father: “asacrifice that the Father accepted, giving, in return for this total self-giving by his Son, who 'became obedient unto death' (Phil 2:8), his own paternal gift, that is to say the grant of new immortal life in the resurrection”.
In giving his sacrifice to the Church, Christ has also made his own the spiritual sacrifice of the Church, which is called to offer herself in union with the sacrifice of Christ. This is the teaching of the Second Vatican Council concerning all the faithful: “Taking part in the Eucharistic Sacrifice, which is the source and summit of the whole Christian life, they offer the divine victim to God, and offer themselves along with it”.
27. At various times in the two-thousand-year history of the People of the New Covenant, the Church's Magisterium has more precisely defined her teaching on the Eucharist, including its proper terminology, precisely in order to safeguard the apostolic faith with regard to this sublime mystery. This faith remains unchanged and it is essential for the Church that it remain unchanged.
Dominick, notice how JPII over and over again focuses on the SACRIFICE of Holy Mass? How many times do you see this in any of the Catholic Updates? He even says, "At times one encounters an extremely reductive understanding of the Eucharistic mystery. Stripped of its sacrificial meaning, it is celebrated as if it were simply a fraternal banquet." Yet, the "fraternal banquet" understanding of Holy Mass IS the focus of these Updates.
He also says, "The Eucharist is too great a gift to tolerate ambiguity and depreciation."
"Abiguity and depreciation". Hmmmm. Could that also per chance mean "sloppily written" as you say?
I am sorry. It is my contention that "watered down" and "sloppily written" catechetical materials, like many of these Catholic Updates and other material, directly leads one into heresy.
