Amen to that. Its amazing to me that the organized religions that resulted from the split with Rome are still making some of the same mistakes as the RCC.
You can do whatever you wish as far as creeds of course. The great majority of Christians use them to differentiate their beliefs from others.
The original creeds were to define the Christian faith regarding who Christ is and the Most Holy Trinity - as differentiated from the various heresies. Some of these beliefs concerning Christ and the Trinity crop up again, even today. Those who hold them have problems with the creed; those that don’t, don’t.
It seems to me that if we really want to evangelize our Christian brothers and sisters that do not understand Biblical Christianity our first step is to live what we preach. The 5 Solas are so beautiful in their truth and simplicity. Sola Scriptura is the only infallible rule of faith for Biblical Christians.
I believe when we get caught up in arguments over creeds and confessions we really aren't trying to evangelize those that suffer from belief in an immature theology, but we are really just puffing ourselves up as being better than they are.
