That He rose Bodily from the grave the third day according to the Scriptures (Matthew 28:6).
That He, only, is the Great High Priest and we need not the intercession of any man, but that Christ ever liveth to make intercession for us (Hebrews 7:24-25).

That in order to be saved, the soul must be born again, “Ye Must Be Born Again” (John 3:3-17).
That every truly born again soul should declare his faith by the act of baptism (immersion in water) setting forth the Lord’s death, burial, and resurrection (Romans 6:4-10).
That the church is a body of baptized believers whose only mission is, not to “reform the world” but to preach and teach the Gospel of salvation to the individual soul (Acts 5:42).
