On December 3rd, 1970, it was decided in Rome, contrarily to the constant Tradition of the Church, that the sacrament of Confirmation could be given with any vegetable oil and not only, as it was the case till then, with olive oil. Consequently, Archbishop Lefebvre was holding the sacrament of Confirmation as doubtful in the Novus Ordo and was advising all those confirmed in the Novus Ordo to be conditionally confirmed in the traditional rite.
Also, on August 12th, 1998, Mgr Tissier de Mallerais, after reading the book called “Le drame Anglican” from Dr Rama Cosmaraswamy, wrote the following : “I came to the conclusion that the validity of episcopal consecrations given according to the rite of Paul VI is doubtful”. This letter of His Excellency Bishop Tissier de Mallerais has circulated a little bit everywhere. Many other theologians having studied the question carefully have come to the same conclusion.,,,"

neoSspx recently declated that they are perfectly the same," semper idem", as +Lefebvre 50 years back. So, was + Tissier de Malerais in error when he concluded that episcopal consecrations were doubtful, and by extention any sacrament they perform?
To be fair, Fr Sherry doesn't represent the entire neoSspx. Throw in a NO "bishop" Huonder and witness the resultant reeky riddle.
