Maybe what is most needed in advancing family history research and the submission of names for Temple ordinances is not so much why we do Temple ordinances as how we go about actually doing family history research. Here is one definition of family history research from the FamilySearch.org Research Wiki:
Family history research is the process of searching records to find information about your relatives and using those records to link individuals to earlier and later generations.Doing family history is a process and it is a process that must be learned. It is not enough to be motivated, it is also necessary to have some specific training. Some of us acquire the basic training through our life experiences. I acquired my own background in computers, research, library use, languages, reference materials etc. long before I became interested in family history per se. Some people need to acquire a few or all of those types of skills before they can feel comfortable researching their family history. If we ignore the need to acquire certain skills to do family history, we will ultimately find that people become frustrated and do not value either the activity of family history or its goals.
A good example of the type of information that is needed for doing family history research is the new presentation in the FamilySearch.org Learning Center called, "Family History Research Basics for Consultants." This type of presentation needs to be extended and used for everyone who starts out doing their family history. Paraphrasing what one of my friends said to me recently, we want the members to do their family history, but we focus on the end product and not the process. We want them to have the benefits of doing family history research but talk about advanced topics and do not emphasize enough the basics of starting out. Many members still need to learn how to sign into the FamilySearch.org program. They are a long way from doing productive research. Most of the people I teach and help do not know how to critically examine the information that is already in Family Tree. The new iconic help system is pointing people in the right direction, but they still need to be taught what the icons mean and what to do about the problems.
It is time to develop some really basic training and figure out a way to get more of the members, including the leaders, to take the time to look and learn.
