You don’t need to take my word for it, nor was I claiming or implying that Augustine was infallible. It was stated that Jesus did not break the gates of hades, and I provided one link (out of many) that shows that this is a common belief. I provided a link to the Summa Theologica, which quotes Augustine as saying just that, so there is nothing “cherry-picked” about it.
I’m not asking you to accept anything. The purpose is to correctly portray the teachings and doctrines of The Church of Jesus Christ of Latter-day Saints. I’m not concerned with whether someone accepts them or doesn’t (nor am I concerned with accepting Catholic/Orthodox/Lutheran/Anglican/Baptist/Muslim/etc teaching, besides accurate portrayal of their own teaching).
Latter-day Saints believe that the apostasy and restoration of the Church of Jesus Christ was predicted by ancient Biblical prophets. We believe that the apostasy of the Lord’s Church was not a failing on His part, since He is perfect, but a failing on the part of humans, who are not perfect, and are allowed to freely choose, and God will not force them to do something they do not want to do. We see this principle throughout the Bible, throughout salvation history. The people reject the Lord’s servants, God withholds blessings/guidance from those that do not desire Him, then He calls another prophet to lead the people. However, there have always been true believers, and God guides those people, and does not withhold His guidance from them. We believe that this was true even during the apostasy of the Church of Jesus Christ, until the Lord, in His own time, decided to call a prophet and restore His Church.
Again, the Bible is full of examples of apostasy and restoration throughout history. It does not mean that the gates of hades prevailed, since, for one reason among many (as already discussed), the Church of Jesus Christ has been restored by God. Further, the Church of Jesus Christ believes that God has provided a means, through ordinances in our temples, by which those that did not hear the Gospel in this life, whether in recent times, or anciently, can have that chance to accept the fullness of the Gospel of Jesus Christ. In the same way that Jesus Christ descended to Hades and rescued the faithful, many of whom were probably there for “hundreds” or “thousands” of years, these people also are rescued through Christ’s atonement and God’s priesthood. Latter-day Saints also believe that all people have the Light of Christ, even during times of apostasy, and those that seek after God will hear His voice.
