The Catholic Church teaches "Outside the Church there is no salvation." However, that must be understood as the Church understands it. The route to salvation is repentance and reform. That route is open to everyone. The Sacraments of the Church are intended to make that route easier for Catholics, but that route is not impossible even in the absence of the Sacraments. The Church has never taught that non-Catholics are automatically damned. God is not a monster, and wants everyone to be saved. If you are damned, it will be by your own actions, not for any other reason.
So...if you're a Catholic (in good standing with the Church, one presumes) you go to Heaven. If you're a Christian but not a Catholic, you might go to Heaven (the phrase, "not impossible" isn't likely to fill non-Catholics with confidence). If you're not a Christian, convert or burn in Hell, you pagan.
Does that sum it up? Can I at least hope for the 1st Circle, where the Virtuous Pagans wind up? 'Cause, y'know, Dante. :-)
