It remains the only statement of faith that is accepted by all major parts of the Christian faith. The major point of the Nicene Creed is that it defines what the church believes about the nature of God. It establishes the idea that all Christians must believe in the idea of the Trinity.
Absolute Truth does not change. The truth of Jesus Christ is the same yesterday, today, and forever.
This belief is either true, or it is not true. It cannot be both. It behooves you to find out which one it is.
The same message is NOT coming from everywhere.
