Then Lefevbre's ordination is invalid--- a disinterested third party can sometimes administer a sacrament such as baptism but I would imagine that under Canon Law, a cleric is no cleric at all if he has taken an oath of hostility to Holy Church. And if one is not validly ordained, I cannot see how he would even be eligible for episcopal consecration.
I still want to know from where the accusation of Mrs Martinez comes. As mentioned before, two of her primary sources are extensive private interviews with the names of Lefevbe and Williamson.
The Particular books in her biblio that I prchased in search of the charge that Marcantonio Pacelli actually was an employee of the Rothschild bank are devoid of the accusation.
