The church of The Book of Mormon did contain these offices:
The Mormon Church prides itself in having a church structure made up of a prophet and twelve apostles. Such they claim was the structure of the New Testament Church and a sign of the True Church.
The truth is, the apostle Paul who wrote those statements was not even part of the church in Jerusalem (Galatians 1:1,11-12,15-19), neither were the prophets (Acts 13:1-3).
In fact, Paul states clearly that the apostles and prophets were separate from church government:
And God hath set some in the church, first apostles, secondarily prophets, thirdly teachers, after that miracles, then gifts of healings, helps, governments, diversities of tongues. (1 Corinthians 12:28)
Salvation is in submission to the Lordship of Jesus Christ, and in the basic ordinances as laid out in the Bible and Book of Mormon. It is not in any church, for The Church IS the Body of Christ (3Nephi 26:21, D&C 10:67).
