What you call "quibbling" are basic concerns of charity, respect for truth and the ninth commandment, which by the way translate into Canon law.all this quibbling
According to the English translation atp.396 of https://isidore.co/calibre/legacy/g... Co - Benedict XIV, Pope & Peters, E_7786.pdf :
Canon 1325 said:§ 2. After the reception of baptism, if anyone, retaining the name Christian, pertinaciously denies or doubts something to be believed from the truth of divine and Catholic faith, [such a one is] a heretic; if he completely turns away from the Christian faith, [such a one is] an apostate; if finally he refuses to be under the Supreme Pontiff or refuses communion with the members of the Church subject to him, he is a schismatic.
That clause which I emphasized is "quibbling" also to you ?
the real point: there is a radical irreconcilability between Guénonism (or any form of esotericism in general) and Catholicism
Yawn. Yet another self-appointed heresy detector. Personally, I prefer to quote official documents of the Catholic Church when accusing some doctrine or someone of heresy, which is no small matter to me.
He despised the idea of eternal salvation or damnation, peculiar to Catholicism
What ? Eternal heaven and hell exist in Islam also, not as minor concerns, and Guénon ended his life living as a Muslim.
He (...) champions a Gnosis or “metaphysics” which leads to the supreme identification with the undifferentiated Absolute
And how does that disagree with the Catholic idea of Beatific vision ? Guénon wrote that the Hindu nirvana is "obviously of a much higher level" than the Christian paradise, but like Catholic author Borella and others I find that not obvious at all, doubtful and unwarranted. By the way, some "Catholic Guenonians" argue that it's the other way round, that the Christian absolute heaven & absolute hell are of a "higher level" than the Hindu reincarnation cycles with their relative heavens and relative hells.
