The Sacraments are not “barriers” to God but direct access. My problem with your theology is that its makes the individual the immediate judge of his./her own actions. It depends on what lens ones reads scripture, which role one assigns to the Church. What, for instance, one males of the “cloud of witnesses” spoken of in the 12th Chapter of Hebrew. Protestants interpret this witness as no more than the good example of the righteous. Catholics as their continuous presence with us as members of the Heavenly Court. We and they are part of the communion of saints, except they can see the Lord.
And my problem with the “Sacraments” is that they aren’t Biblical and are in direct contradiction with the plain meaning of scripture read alone without the aid of countless traditions compounded on each other.
Speaking of a ‘Cloud of Witnesses”. One wonders how it is possible that Mary or some Saint can hear our prayers, when you have more than a billion Catholics across the world praying to the same Saint or Mary at the same time all across the world.
This means that being in this “cloud of witnesses”, gives the individual human soul the same qualities of God: Omnipresence and omniscience. Of course, it’s possible that Heaven exists outside of any sense of time, so presumably when I die, I could enter heaven at the same “time” as someone who died a thousand years before me did. Nevertheless, they’d still be offly busy.
