Dear Brother,
I'm writing this post to offer some information about the TFP group. It is a Brazilian organization, and it is kind of secretive, or at least discreet. There is conflicting information even here in Brazil about their beliefs and purpose.

All I can say is that this group is regarded as a far-right group, and that there is more to TFP then simply being a "catholic" group They are more like a political organization.

Although they are not a political party, they are certainly a group with a defined political (and social) ideology. And because of the content of their beliefs, they are seen as far-right wingers. (some see them as fascists, but I have not enough intel to make that assessment).

It is true however, that being catholic is part of their identity as a group, and that part of their set of beliefs is of a religious/spiritual nature. I believe that the members must all be catholics, that they attend Mass, but I have serious doubts about their being in full communion with the Church.

Yes, their views on the Family, for instance, correspond to that of the Church, because they are not liberals. But, for example, their social views can hardly be reconciled with the Church's social teaching, so they turn a blind eye to it. They are conservative in Liturgical matters, but I am not sure if they are in rebellion regarding Vatican II.

Their voice is almost not heard in the media, but they have links to one of the (rival) branches of the (former) Imperial House of Brazil (deposed in 1889). The entire Imperial Family is Catholic, but one sub-family of "claimants" is TFP, while the other has strong ties with he Hierarchy here in Rio

In São Paulo city, they also have TFP "altars", but I am not sure if those "altars" are Church altars or something else

Just before writing this post, I visited their website and I learned that there has recently been a judicial dispute regarding an election to their Board of Directors. According to the new Directors' website, one of the former Directors (Prince Bertrand), blamed the victory of the other group on a "conspiracy plotted by left wing catholics" and even complained about the "lack of action" of the Pope and the Holy See in dealing with them. I don't know if this information is true, but you see that there are rival factions within the organization, and perhaps not all those factions are in communion with the Church. (although all claim to be catholic).

My opinion is that they use the Chuch and their identity as catholics as a means to advancing their political aims and to create a bond. It is possible that they use the notion of fidelity to Church doctrine as a means to include their own teaching in the package. About what they do as a group, I don't know. They are an obscure group and do not have (or avoid) press coverage. The Hierachy doesn't condemn them explicitly but keeps distance from them.

I would keep distance from them too. There are safer ways of being conservative and catholic
