The recipients are most certainly not receiving the Body of Christ - but I doubt that this minister claims that they are receiving the Body of Christ? It seems like he is attempting a symbolic communion since they are gathering in Christ’s name and then sharing food and drink. However, even if they accept it to be only symbolic it still makes a mockery of the Last Supper - juice and cookies!.. An absolute joke, in my opinion.
There are a number of reasons why this cannot possibly be the Body of Christ (and you will find more in-depth discussion on other threads). Firstly, he is not a validly ordained priest. Not that we could call this Sunday School gathering ‘Mass’, but only a validly ordained priest has the power to consecrate bread and wine so as they become the Body and Blood of Christ. Also, look at the ‘gifts’ he is using - juice and cookies… Even if he was a validly ordained priest, I doubt that juice and cookies would meet the requirements for a valid consecration. After all, Christ took bread and wine, not juice and cookies.
With regard to your question about the recipients being saved by receiving this ‘communion’, I would say no. Having said that, receiving the true Body and Blood of Christ does not in itself save a person - the Catholic position, as opposed to a fundamentalist one, is that salvation depends on the state of a person’s soul at death. So receiving Christ at Mass brings many graces to the recipient which will help them live good Christian lives, but it is illogical to think that one will be saved by receiving Christ while at the same time ignoring His commandments of loving God and neighbour.
I do think there is more that you can do than just praying for these people (although, don’t underestimate the power of prayer!). They may have left the Catholic Church of their own free will, but their ‘conversion’ has come about by misleading and untruthful evangelists. So, I think you have a duty to act practically. If you have doubts about your faith, then I suggest you educate yourself in Catholic doctrine, history and Scripture. Then when you have discovered the truth of the Church and the falsity of these evangelical groups, you will be in a position to rationally explain and clarify the erroneous practices some of your family have become involved in. There are a number of good apologetics books out there which will help you answer questions you may have about your faith. One of the most highly regarded books is Karl Keating’s ‘Catholicism and Fundamentalism’, which I am reading at the moment - this will help you greatly.
