“The priests of Noah were corrupt and their priesthood one of defilement and debauchery. Of interest but unclear in the Book of Mormon is what authority if any the priests had who were consecrated by Zeniff. Assuming Zeniff to have been properly ordained, it may well be that Alma traced his authority to this source (see Mosiah 18:18)” (McConkie and Millet, Doctrinal Commentary, 2:200).
