The church was in spiritual darkness during the dark ages for the span of several centuries. God rised several reformers who brought the church back to Bible but the churches formed as a result of the protestant reformation didn’t leave many of the false teachings of Papacy. For example many churches had a wrong form of baptsim, they continued to keep Sunday Worship instead of Biblical Sabbath, also the teaching of eternal burning of hell and immortality of soul were among the many false teaching which they clinged to after leaving Catholic church.
That is why God rised a prophet who can restore the church to the correct teaching of Bible.
1. A prophet unlike reformers and theologians is inspired and can give direct message from God.
2. When different theologians can interpret Bible in different way a prophet alone can give infallible interpretation of the scriptures because she is inspired.
3. When Satan has brought thousands of deceptions and counterfeits there is a need for a prophet to expose them.
Besides doctrinal and prophetical role Ellen White has a major role in the following areas also
2. Health and Healing
If you have read reports on Adventist have the longer life span on planet earth it is because God has given us the health message through the prophet Ellen White.
