I hate to be the bearer of bad news, but according to Fr. Rousseau (Resistance - Switzerland):
"Who knows whether, in the future, priests of the Society will not go begging for the Holy Oils of bishops consecrated by Bishop Williamson, as happened after Easter this year in Germany, when these priests refused the Holy Oils consecrated by Bishop Huonder at the seminary in Zaitzkofen? (
Note, by the way, that these "German" Holy Thursday Oils were given for all priests of the Society of St. Pius X residing in Asia: to say that the Oils will have been circuмscribed to a limited country is false)."
