Did prayer to saints and angels develop in a way comparable to the development of the canon?

When the historical evidence against a Roman Catholic belief is brought up, a common Catholic response is to compare the development of that belief to the development of the canon of scripture or Trinitarianism. Here's something I recently posted in a YouTube thread about the subject. YouTube has had a problem for years with some people's posts sometimes not appearing. Many of my posts don't appear after I submit them, and I still haven't found a way to determine which posts will go through and which won't. The one below didn't go up. Here's a link to the YouTube comment I was responding to. You can read that comment and the surrounding context if you want more information about what led up to my response below.

Cameron Bertuzzi's Backfiring Cannon

Cameron Bertuzzi recently put out a video about the New Testament canon. I've addressed the subject many times, such as in a lengthy 2009 series here that discusses the issues raised by Cameron. Or see here for a more recent overview that addresses some of the issues more briefly. For a listing of all of our posts under the "canonics" label, go here (keep clicking Older Posts in the bottom right to see more).

What I want to do in this post is briefly address some of the problems with Cameron's video. You can read our earlier posts for more.
