ALL OF THE SERMONS ARE AVAILABLE ONLINE, AND CANNOT BE TOUCHED BY THE SSPX.
They are on the website called the pirate bay.
I will outline here how to access them. Follow the instructions carefully, ... OR just ask a teenager to get them off the site for you.
1. You need a thing called a "torrent client" to download the files. Pirated files are not normal web browser files. For security it has to be this way. (Take that Menzingen!) Google for it, but my favorite is "free download manager". It is a safe piece of software.
2. Google "pirate bay proxy".
3. Try the various links in the website. Many will not work. Be patient. You will get one eventually. Be aware that you will get many annoying pop ups. You should obviously have your anti virus software operational.
4. When you get onto the website, just type "lefebvre" and you will only get two results.
5. When you get into the relevant one, you will see "get this torrent" with a magnet sign beside it. Right click on it, and copy the link.
6. Paste this into your torrent client, and download it, and go about your other business. It is a big file and will take a while.
Any other questions, send me a private message.
