"As far as I was told by members of the canonical Polish church, the break occurred precisely because "metropolitan" João was already involved in other schemes back then."
It would nice if you presented evidences for that.
"First he had been elavated just to the order of bishop, but presented himself everywhere with the rank of metropolitan."
Another lie. He was elevated to Metropolitan by Metropolitan Basil of Poland after the death of Metropolitan Gabriel.
"He also supported a parish in Portugal where a gypsy "prophetess" was treated as a bishopess, even sitting on the bishop's throne and making readings in her spare time."
The Orthodox Church of Portugal had been trying to help (spiritually & liturgically) a place of cult known as "Ladeira do Pinheiro" almost since the beginning of the Orthodox Church in Portugal. A monastery was founded there and the "gypsy prophetess" that Fabio Leite talked about was actually the Abbess of that monastery. Everybody knew about "Ladeira do Pinheiro" in Brazil, since they entered the Orthodox Church of Portugal in 1986. It is a controversial place and the Orthodox Church of Portugal left "Ladeira do Pinheiro" in 2003.
"To close the deal he was involved in money embezzlement, using parishoners' money to buy land in the name of the church and reselling them with a profit for himself."
Once again, it would be nice if you presented evidence for what you are saying.
