Catholic opinions on who can be saved and how many are saved covers a wide range. On the far left, we have some claiming that perhaps no human souls are sent to Hell, and that we can hope that no one will be condemned to Hell. Perhaps, they say, Hell is empty of human souls.
On the far right, some claim that very few are saved, that most Catholics and few if any non-Catholics or non-Christians will be saved. In this view, the elect are very few indeed.
My own view on this topic is fairly liberal. Many souls unfortunately are sent to Hell, but only for unrepentant actual mortal sin. Most persons obtain eternal life, though usually by way of the purification of Purgatory. I consider that non-Catholic Christians, and non-Christian believers can be saved by the love of God and neighbor, despite grave errors in their religious beliefs (due to invincible ignorance). And non-believers can be saved by love of neighbor, due to invincible ignorance concerning the existence of God.
Baptism is necessary for salvation. But I consider that a baptism of desire or of blood is available to those who have not been baptized with water.
What does everyone else think about the scope of salvation for us poor sinners? Are many saved, or few? Is the path to salvation necessarily one of conversion to Christianity or Catholicism?
