Yeshua being the only way to the Father is not a belief exclusive to Catholics.I am an old fashioned Catholic who sees some sense in some of the non-Catholic religions, but JESUS is the way to Heaven and ther is no other way.
I am checking out the Society of St Peter or whatever the official title is. It was also started by Lefebvre, so I know it is a good thing. I have read up on him, a true Catholic.
