MTC Center Training Missionary
I couldn't find the article, but I had heard that missionaries were no longer required to memorize the discussions. While I think it is good to not follow an entirely memorized script when teaching, I wonder what is being done to ensure that these young missionaries have the necessary knowledge to adequately teach the gospel. Sad to say, but many of these young men do not have the doctrinal background they really should before entering the MTC. At least by memorizing the discussions, they are learning the fundamentals. I think this is especially been an aid in the past for foreign language missionaries. They pretty much learned to speak the discussions as an aid to learning the language.
I do believe the brethren making these decisions are inspired, though, so I am sure this is the correct direction in which to go.
