And about differences in denominations... After the Apostles, differences have always existed. As early as 325, there was a great difference of belief in the early churches: Arian heresy stated that Jesus was a created being. The issue was not settled finally until the Council of Constantinople in 381.
If churches leaders could disagree on the divinity of Jesus in the 300s, one can only imagine what other doctrinal differences existed at the time.
And so the Nicene council created the Nicene Creed in agreement with the Scriptures. The Nicene Creed lays out the basic foundation that a church must accept to be part of the catholic and Apostolic Church. The Nicene Creed uses the term catholic (small c) meaning universal, not the Roman Catholic Church.
The Nicene Council deposed 2 bishops because they would not profess the divinity of Jesus. They didn't touch on the method of baptism. They understood that churches would have differences of opinion. They created a creed as a measuring stick. My synod stands up to that standard. We are part of the universal and Apostolic Church.
So why does the present Catholic Church disagree with the Nicene Creed and the decisions of the Nicene Council? My synod, the LCMS, believes in the Nicene Creed. We are part of the universal Church of believers. Why does the Catholic Church claim otherwise?
Where did you get that idea? The Nicene Creed is the very structure upon which the Catechism of the Catholic Church is built.
