Yes.
And I also believe in obeying the Ten Commandments, the forgiveness of sins and remaining in His Church, outside of which there is no salvation. And I believe that there are Christians, both Catholics and Protestants, who are in Hell.
I do not believe in the prejudged nonsense, however.
If you're thinking you have to keep the Ten, then you have to keep all of the OT Law.
There is no salvation outside of faith in Christ. Belonging to a church isn't what saves you. That's what John 5:24 is about.
Do you have a Scripture reference that backs this up ebb??
