No. I also do not believe there is any exclusive “One True Path”. That said, I’ve known folks who were in congregations of no more than a couple dozen that met in an old 7-Eleven storefront church that were convinced that they had the One True Path.
The point is that Protestantism can not be legitimately referred to en mases when proclaiming one doctrine is better than another - So if I assumed you were posting from a Catholic perspective, I apologize - that is generally an error that is confined to the Catholic perspective, but I guess there are always exceptions.
