On your topic of sharing resources about Luisa’s writings, they are at this point unapproved private revelations, as I understand the Vatican has not yet approved them, so we cannot discuss the material of the writings or share resources about them because posting material from unapproved private revelations is against the TOS of the forum. I know there is one priest who promotes her and sells his own translation/ condensed edition of her extremely voluminous writings that he claims has some kind of Vatican approval, but because he is not affiliated with the Archbishop of Trani who is in charge of the project to translate her writings and eventually prepare some edition that will (hopefully) be approved by the Church for people to read, I find his claims a little sketchy, especially since he seems to have made his own little cottage industry out of promoting her. I myself might still read his book but with the understanding that it is not the official edition, which has yet to come out of Trani. So his book might have errors in it.
On your topic of the cenacle, many churches have such cenacles. I don’t think the Vatican has an objection to them at this stage. As you said, Luisa is on the path to sainthood, and such prayer groups are often formed by those who want to promote the cause of a particular person. They are considered “evidence of cult” and are important for showing the Vatican that the person being considered for sainthood has a following. I would first ask if the local pastor and bishop have approved the cenacle meeting. If the meeting has been properly approved at the local level, then it is up to you whether you go, knowing that you will likely be exposed to various theological concepts that the Vatican has not yet approved and that some theologians like Fr. John Hardon have objected to.
I have been to a few of these cenacle meetings because I got curious after the last time somebody asked about Luisa on here. (See the previous thread that somebody posted.) The meetings were interesting from a standpoint of learning a little more about Luisa, her writings, and writings about her. They also pray a rosary with some meditations and that also seems okay. However, some of the theology being presented at the meetings was a bit unusual, and not everyone who comes to the meetings is well-grounded in Catholic catechesis. There are certain groups of Catholics who just love to rush to meetings on every new, unapproved private revelation and basically take everything that is allegedly said by the mystic as being truth (often relating it to some political or moral development happening in the world today). As that is not my approach, I sometimes have to step away from that and just learn about the mystic on my own, not in a group meeting. YMMV.
