I would like you to explain how the concept of the Trinity came about and comment on the acceptance of it in various Christian denominations. Are there things about the Trinity that certain denominations believe and others don’t?
The Trinity has been an accepted doctrine of the Christian church in all its major branches (Catholic, Protestant, and Orthodox), and indeed was an accepted doctrine even before it was officially ratified at major church conclaves in A.D. 325 (at Nicea) and in A.D. 450 (at Chalcedon).
