Are there limits to "Progressive Revelation" regarding the nature of God?

## Background Christians commonly hold that God revealed the truth progressively in history in areas of theology like the plan of salvation and law . Many Christians also believe that the Triune nature of God was revealed progressively over time, and that early men may not have understood God to be a Trinity but the Trinity was revealed slowly with "increasing clarity as more and more of the Scriptures were written" . ## Question Given that Christians believe God has revealed different aspects of his nature over time, do any Christian denominations believe there are limits to "progressive revelation"? Specifically, could God reveal new information about his nature in the future such as another person? Or is the understanding of his nature now considered fully complete?
