If you’re a Lutheran, you recognize the authority of the early councils. You also recognize that the Church is granted teaching authority. Sadly, that authority is divided along with the Church.If you’re a Protestant, you can do what you like! The question is, what do YOU consider to be the source of authority? If you think that the Council of Milan where the Apostles’ Creed was mostly formulated, plus subsequent adjustments by the Church, are authoritative, then you are walking down a logical path which will lead you to Rome.
So, my view is where we have agreement, let’s stand together.
The problem with changing the creeds is it can lead to changing the meaning as well. I see no reason to change it.
