Yeti, Archbishop Lefebvre never really addressed the issue of the new rite of episcopal consecration, but you will find that almost all in the Resistance hold to the opinion of Fr Calderon that there is doubt over this new rite 'which cannot be tolerated at the very root of the sacraments' and must therefore be repeated sub conditione.
.
Thank you for explaining this, and, while I understand that the resistance is not a unified body and can't be expected to have principles that are universally agreed upon, I have trouble with your claim here inasmuch as the only statement I have ever read by any resistance priest or bishop is the one by Bp. Thomas Aquinas, in which he said the new holy orders could be valid, and were in fact valid in the case of the novus ordo-ordained Fr. Jahir, and also the fact that none of the resistance priests or, especially, bishops ever made a public objection to Bp. Aquinas's claims if they had an objection to it, and in the absence of such a public rejection of his words I must conclude that they agree with them.
Another reason I have trouble believing that the resistance almost universally reject the new holy orders as always doubtful is Bp. Williamson's claim that the Holy Eucharist can be validly confected in the Novus Ordo mass, which brings us to the next point:
This is the opinion clearly expressed by Bishop Williamson in his ECs, and the reason why there was such an outcry over Bishop Huonder celebrating the Chrismal Mass on Holy Thursday this year.
I never noticed this, but if Bp. Williamson believes the new mass can be valid, then why would he have doubts as to the validity of the holy oils consecrated by Bp. Huonder?
