I have been going through the arguments against Vatican II on this website document by document. Currently, my defense against their many arguments can be found in the Defending Vatican II tabs under the different Latin titles for the documents of Vatican II. I still have a few to go, but thought I would make this a public declaration that defendingvatican2.ca has formally written a defense for most of (hopefully soon all) catholicapologetics.info arguments under the tab principle heresies of Vatican II. Check my defense https://defendingvatican2.wordpress.com/defending-vatican-ii/
Now I have respect for the authors of this website that challenges Vatican II, but I think they are opposing the Holy Spirit and the Pope by saying that the teaching of Vatican II is wrong or in anyway heresy.
