THE CURRENT TEACHING OF THE MORMON CHURCH:

Only L.D.S. have authority to baptize, ordain, etc. They have a two-part system of priesthood—Aaronic and Melchizedek.

"Man cannot act legally in the name of the Lord unless he is vested with the priesthood, which is divine authority. No man has the power or the right to take this honor to himself. Unless he is called of God as was Aaron, he has no authority to officiate in any of the ordinances of the gospel: should he do so his act is not valid or recognized in the heavens."

(Doctrine and Salvation by Joseph F. Smith, Vol.111, Pg. 80.
