“not and issue with Catholics, Orthodox, or Mainline Protestant Churches”
or any evangelical Bible believing church, or Orthodox churches.
Your non-trinitarians are your JWs, your Mormons, your Unitarians. . . the trinity is confessed throughout church history and is part of all major creeds and councils. I don’t believe a non-trinitarian is a Christian.
SDAs are trinitarian to the best of my knowledge.
Another mark of a true Christian church, for me, would be a confession that the Bible is the word of God.
Then the Doctrine of the Trinity probably won’t be an issue for this investigator. I didn’t know the beliefs of Seventh-Day Adventists. Yet I would hesitate to prescribe any manmade interpretation of the scriptures as the definitive word on the subject. I prefer to urge people to seek guidance from the Holy Spirit.
YESSSS!
