There is one God.
Jesus Christ is God manifested in flesh.
Everyone must repent of their sins, be baptized in the name of Jesus Christ, and receive the gift of the Holy Spirit.
Everyone must live holy, separated, and fruit-bearing lives, acceptable unto God.
We are not saved by works, but we are saved to do good works.
Jesus Christ appeared once to deal with sin. He will appear once more to bring eternal salvation. His one and only second coming will be after the tribulation period.
