He's being satirical.
Charles Coulombe will seldom respond to his critics in a direct manner. He'll try to impress them, instead, with his literary ability, and make it so complicated that a critic won't know where to start, in attempting to reply to his response.
For some time, there have been a certain factions within traditional Catholicism which flirt with the occult, though I think that they are relatively small. There are the Perennialists (which may include Rama Coomariswamy, one of The Nine), Forzo Novo, Francis Yockey, etc.
Coulombe will make it seem as if all his occult associations are completely benign. He's always done that. IMO, he's bored with Catholicism, and has sought truth elsewhere. It happens.
