We have recently, finished our defense of Lumen Gentium. Taking anti-Vatican II Lumen Gentium arguments (listed under the Principle Vatican II Heresies) from http://www.catholicapologetics.info/ we have gone point by point to refute the website. They have 5 points against Lumen Gentium. We give 5 responses.
You may find our Pro-Vatican II defense here https://defendingvatican2.wordpress.com/defending-vatican-ii/7-0-lumen-gentium-lg/ .
Thank you for the encouragement. We hope to answer the website’s objections to other works of Vatican II in the coming months.
