"dissenting members of the Church are not an authority".
Well, no kidding.
But......BUT their views are being rehashed over and over again in catechetical texts! Sure, the press companies and their wares have the conformity with the catechism monicker on the cover, or the press copyright page, by the USCCB. As if we can totally trust the USCCB??? Uh, I don't think so.
If you want examples you need go no further than any "Catholic Update" (St. Anthony Messenger Press) which focuses on the Holy Eucharist. Over and over again the focus of "The Real Presence" is the people (to refute that idea see CCC 1373 and Sacrosanctum Concilium 7).
These "Catholic Updates" are used not only in religious ed., but also RCIA. They are nothing more than the "New Age" movement revisited.
Even Archbishop Hughes said, after reviewing 25 catechetical texts they were "lacking doctrinally":
The U.S. bishops Committee on Catechesis has begun work on four projects to benefit the American church, said its chairman, Archbishop Daniel M. Buechlein of Indianapolis. Areas to be covered in the committees work are education in human sexuality, the education and formation of catechists and catechetical leadership, the development of doctrinal guidelines for high school-level catechetical instruction and a project to outline key doctrinal elements in the Rite of Christian Initiation of Adults. Archbishop Alfred C. Hughes of New Orleans said the ad hoc committee had reviewed 25 high school catechetical texts since mid-2001 and found most of them lacking in key doctrinal areas."

(uh, fond this on a Google search in America magazine.......not exactly "in conformity" with the bishops is this magazine).
I suggest a search for these findings more thoroughly and get an opinion from a different website.
The PRE-DOMINANT way the "Real Presence" is being presented today is "in the assembly". Many "powers-that-be" DO NOT want to "go back" to the days of "coookie worship". After all, the will say, "The Eucharist is not confected to display in some baroque monstrance." Uh-huh. I guess this is why JPII is hammering Eucharistic Adoration so hard these days (see Ecclesia de Eucharistia #10, and The Year of the Eucharist #18).
Suggested reading to research bad catechesis which is still going on in religious ed. circles in the Church:
"Catechisms and Controversies" by Msgr Michael Wrenn and "Flawed Expectations" by the same author with Kenneth Whitehead (both printed by Ignatius Press). Also "In the Presence of Our Lord" by Fr. Groeschel.
My thoughts, FWIW.
