The most obvious change involves the reorganization of the Melchizedek Priesthood quorums. Heretofore, a large measure of the responsibility for temple and family history work has been assigned to the High Priests groups in the Wards with direction coming from the High Priest Group Leader. For example, the description of the responsibility of the High Priest Group Leader from the Family History section of LDS.org has been moved, altogether, to the Elders Quorum President Resources. Here is a screenshot of the new page.
What about existing Temple and Family History Consultants? The training responsibility for Ward Temple and Family History Consultants is currently assigned to a called Stake Temple and Family History Consultant who is trained by the Area Temple and Family History Consultants who are then trained by the Area Authority Seventy and FamilySearch. It looks to me like much of responsibility for all areas of the Ward are now the responsibility of the Elders Quorum President including the responsibility to support and coordinate the efforts of the Temple and Family History Consultants. The Ward Temple and Family History Consultants should be offering to help and train everyone in the Ward, including the Ward Priesthood and Relief Society Leaders.
The bottom line for Temple and Family History Consultants is exactly the same as it has been: they are to help the members of their Wards to have a personalized discovery experience. We all have the responsibility of learning about our own callings. The resources for training and support of Temple and Family History Consultants are already available. Just keep on doing what you are called to do. There is no change in that.
