The Syriac OC in Brazil is comprised of a few immigrants and a number of converts. In the video we see the long-time representative of the Syriac Patriarchate, Fr. Gabriel.
There is a *big* group of converts though who used the name Syriac without authorization for many years. As far as I know, they had contacted the Syriac Patriarchate and were ordered to start discrete Christian missions and would be under observation during this period. They did not respect the order and introduced themselves as due representatives of the Syriac church despite Fr. Gabriel being the only legitimate one. That did not prevent them even from joining the Brazilian Council of Churches in the name of the Syriac Church.
When I denounced this farse on the internet, they started sending me hate mail and even threatened to put me on legal trial. Had it not been for the kind intervention of a State Attorney from S. Paulo they probably would have continued their online aggressions. It seems that once the news spread that they were perpretating a lie questions started being asked and the answers could not be given.
After some time of silence, they reappeared with a real document acknowledging their reception in the Syriac Church. *Today* they are really members of that communion.
I have not found any news in Portuguese about that. Considering their past, I would not be surprised to learn these numbers are "exagerated". But it could be true too. It is an unfortunate reality in Brazil that "fake Orthodox" - and even fake OOs - are far more pro-active in "missions" than the canonical Churches. I really hope that their acceptance in the Syriac church turns out to be something good, and not something that will backfire in some years against the Syriacs themselves.
And the translation they show in the video of the Lord's Prayer is the New Age interpretation of the Aramaic translation of the original Greek text.
