With a number of representatives from a number of other Christian communities came to the installation of Pope Francis, it is a sign that the prayer of Christ that all believers be one as from John 17 is coming to reality over the course of time.
I’m sorry to inform you that, until the Catholic church reforms their egregious errors, there is no way true believers can or should get together with the leaders of the Catholic church.
I will not go over the many reasons I hold to this belief, suffice to say, it begins with the very idea that any man is the voice of Christ on earth which holds more importance over any other man.
I, you, and any person on this planet can go directly to Christ and gain forgiveness. Not John, Paul, nor Peter was to be elevated to such stature as the Catholics hold the Pope.
So I reiterate, there is no common ground with Catholicism until the church rectifies it’s many heretical beliefs.
