Hymenaeus and Philetus are included among persons whose profane and vain babblings will increase unto more ungodliness, and whose word "will eat as doth a gangrene. The apostle declares that Hymenaeus and Philetus rection are of the number of such people as those just described, and he adds that those two persons "concerning the truth have erred, saying that the resurrection is past already, and overthrow the faith of some." Then, for the guidance of Timothy, he goes on to say the seal upon the foundation of God is, "The Lord knoweth them that are his: and, Let every one that nameth the name of the Lord depart from unrighteousness." The inference intended is, that though Hymenaeus and Philetus had named the name of Christ, they did not depart from iniquity. There is no doubt in regard to the identity of this Hymenaeus with the person of the same name in 1 Tim. Accordingly, the facts mentioned in the two epistles must be placed together, namely, that though he had made a Christian profession by naming the name of Christ, yet he had not departed from iniquity, but by his profane teaching he proceeded unto more ungodliness, and that he had put away faith and a good conscience and had made shipwreck of faith.
The error, therefore, of Hymenaeus and his two companions would amount to this: They taught that "the resurrection is past already,", circa 50AD–65AD, that there shall be no future resurrection.
