IMO, Omlor's article Res Sacramenti obliterated the validity of the NOM.  I used to have his book and have read all of his articles many times.  Now, one can only find it on True Restoration and they are gouging people for $99...lol...it originally sold for $30.

His anti-una cuм piece was great, too, right up until he tried to answer a few objections.  He failed to do so in a convincing manner and that was that.  Anyway, good man, great writer whom I pray rests in peace.

Agreed that his book was devastating for those who continued to defend the validity of NOM, applying PROPERLY the principles of Apostolicae Curae.  SSPX spun the teaching of Leo XIII into being generally about "intention", bujt Leo XIII explicitly stated he meant he intention of the RITE, saying that the Church does not judge the intention of the minister, but only that expressed by the Rite, and at one point says that even after the Anglicans "fixed" the essential form, it was still invalid ... due to the intention of the Rite to change the Catholic Rite, and that no amount of internal intention could validate the invalid Rite.
