Lad,
Of course LoT promotes Pelagianism, my point was if there were no Mckenna, Fahey, Fenton, Lefevbre (to name just a few),..... there would be no LoT, Nado, Bosco, Bumprhy Hogart ,etc... The latter just continue to promote the Pelagianism the former held as Catholic teaching. If the latter are heretics, so are the former.
Oh, now I see what you mean. For the most part, that's true. In a of these cases, though, there's not enough data to ascertain the nature of the error. In a couple of these cases, all we have is an offhand comment that verbatim contradicts one or another EENS definition. Not sure if they think that there's some distinction that makes their position valid. +McKenna and Fahey have said that Jews can be saved (verbatim contradiction of EENS definitions). +Lefebvre said that people can be saved in non-Catholic religions (contradicts Pius IX and also EENS). Fenton goes into the most detail, but he never explicitly discusses the role of the Sacrament of Baptism in a BoD scenario, i.e. whether in some sense Baptism remains the instrumental cause of justification. That is the key to whether or not an articulation of BoD is heretical. If in promoting BoD you are saying that people can be saved without the Sacrament, then that's heresy. If you say that subjective dispositions are salvific
ex opere operantis, then you're a Pelagian. But most of these sources don't get into enough detail for me to determine the exact nature of their error.
With LoT, however, I have direct knowledge of his pertinacity in these specific heresies. I have even offered him ways in which to continue professing belief in BoD without heresy, but he's refused to take that course.
