"We believe that there was a general apostasy from the Church of Jesus Christ, and that this apostasy resulted in the loss of apostolic authority from the earth. Men substituted their own wisdom for divine revelation, and the saving ordinances of the gospel were changed or lost."— LDS Teaching, Doctrines of the Gospel Student Manual, Chapter 16
The Apostles are dying off; corruption enters. No valid priestly authority remains after the last Apostle's death (c. 100 A.D.). The restoration of all things must await Joseph Smith 1,730 years later.
No valid authority, no valid sacraments, no valid Church. Any organized Christianity is apostate — a shell of the original, corrupted by Greek philosophy and human innovation.
The Church is irredeemably apostate. Martyrs dying for the Faith are dying for a corrupted religion; their deaths do not demonstrate God's presence with the Church.
Some LDS apologists claim the Council of Nicaea (325) was the moment the apostasy was "institutionalized" — when Greek philosophy permanently corrupted the doctrine of God.
All Christian activity — councils, martyrs, theological writing, missionary expansion, liturgy — occurs under an apostate institution with no valid sacraments or authority.
The Crusades, the scholastics, the mendicant orders, the mystics, the martyrs of the Reformation — all occur within an utterly apostate Church. God is silent on earth until 1829.
The Historical Verdict
For the LDS claim of total apostasy to be true, the following must also be true: every bishop was corrupt in every century; every martyr died for a false faith; every council was demonic in origin; every saint was deceived; every sacrament was invalid; and God was utterly absent from the earth for 1,700 years — despite His promise that the gates of hell would not prevail against His Church (Matthew 16:18). The historical record does not permit this reading. The LDS "Great Apostasy" is not a historically defensible claim. It is a theological necessity invented to justify a new revelation.
