I did a thesis on topics like this over ten years ago, and even now it is still hard to trace things like apostolic succession and sacramental validity. If he was born Catholic and became an apostate to receive orders in the Charismatic Episcopalian Church, his apostacy is considered an “imediment to ordination” and may be why he was not reconciled into holy orders as a returning Catholic. If the Brazilian Church does in fact have apostolic succession, but ordained this man as an Episcopalian priest using an Anglican rite or accepting the 39 Articles, then his ordination is almost certainly invalid, because at least 2 of the 39 Articles are virtual disclaimers that the ordination is NOT intending to do what the Catholic Church does in ordination or the sacraments. Finally, and I mean no disprespect, but I am familiar with some of these start-your-own-denomination autocephalous outfits, and while some are sincere others are quite unbalanced and would not be considered for Catholic orders.
