Imho, normally it's better to post a link than throw up something on a thread that's longer than the main article itself as that was. It disrupts the continuity of a thread and wears out the scrolling pinky. If your intent is to have everyone have to read it since it's so long, then it should be its own thread.
Luther's teaching on predestination is for the most part tangential to this thread.
I have a torn opinion about long follow-on posts.
Mostly, I'd rather have them posted in their extensive glory. Saves me linking elsewhere--sometimes a bothersome or futile effort.
My page down button works very fast and well. Hasn't broken my finger, yet.
I think getting annoyed over such a small thing is indicative of a bigger problem.
