Proper method of baptism.

[dgrichards]

During a baptism the priesthood holder should raise his right arm to the square. If he raises his left arm to the square and performs the baptism will the child that was baptized need to be re-baptized?

Short of finding a clear answer in a Handbook, I think you're going to have to run that one by the stake president or mission president. If he's not sure, he can ask the area authority.

This is something that you'd hope the witnesses would catch so it could be repeated right away in the font. After the baptism is over, scheduling a rebaptism will be difficult, if it's necessary.

Sometimes there are allowances made in ordinances whe n a person is physically disadvantaged – for example, if the baptizer doesn't have a right arm.

Handbook 2 says that the person must raise their right arm to the square - https://www.lds.org/handbook/handbook-2 ... eng#20.3.8

It also outlines how to deal with individuals who may have disabilities -

Actually the only thing that can invalidate an ordinance is if the person performing it didn’t have the proper authority. The ordinance you describe is valid for God knows our intentions and would not condemn someone because of the errors of man.
