The first half of this 2003 article was sort of interesting, going into the pros and cons of the two main approaches, the lectionary based and the curriculum based.
It mentions Bishop Wuerl going to the curriculum based method in his diocese. If that appeals to you, maybe contact them. What about your own diocese? I think mine, Sacramento, is fairly involved with the direction taken at the parish level. I would think your diocese would be able to offer you some assistance and resources.
I was looking for the manual our RCIA team uses but couldn't find it easily on the net. They take a lectionary based approach but relate the readings to specific doctrinal and discipline items and refer to the Catechism.
I've been a sponsor for several years now and I would prefer that they emphasize the doctrinal and discipline more than they do. Might as well give the catechumens and candidates everything up front before they commit themselves. They're adults, they can handle it. I think the precepts of the Church and things like penitential observance on Fridays bear mentioning more than once.
Leave room in every session for their questions even if they are completely off the topic. It's all for their benefit so their questions are really important.
And if anyone uses the phrase 'the spirit of Vatican II' I believe, as RCIA director, you are authorized to thrash them soundly about the head and shoulders.
LOL!
Personally, I don't like the lectionary approach which leaves too much room for loosy-goosy stuff. The sessions end up being too much sharing-how-you-feel chatty sessions and left little room for actual doctrinal teaching. That's been my experience anyway.
