the caution on this site review is well taken applied to the 2000 materials, which is what are reviewed. as previously stated if your parish is weighing this decision today, please look at the new materials which are quite different from the 2000 version.
Leadership and facilitator training is key to the success or failure of this program. If the parish does not understand what this program is about, and if it has unrealistic expectations, it won’t work. If a small core of dissenters gets hold of this and uses it to push an agenda they can destroy a parish. If it is done right, it has the potential to turn a non-involved inactive parish into the opposite. Spend a lot of time exploring the whole notion of small faith sharing communities, which are the core of this and most similar renewal programs, They work, they have the potential to do magnificent things for parishes and parishioners, they can be life changing, but like anything else powerful, in the wrong hands can do damage.
Renew is not a “charismatic” approach, it is an evangelization approach.
I do urge strongly anyone investigating this or any other renewal program to go to its website and check out its links. I am by no means recommending this above other similar programs, but your decision will not be made easier by relying on older materials no longer in use.
