Where can I find this? Is it in the catechism?
There are lots of places that you can start this journey of exploration. For a glimpse at the breadth of recent scholarship on this issue from mostly Orthodox but some Catholic too, you can start
here. Although the CCC still has a
small section on Hell, there are other Catholic catechisms that assert things like, "Neither Holy Scripture nor the Church's Tradition of faith asserts with certainty of any man that he is actually in hell. Hell is always held before our eyes as a real possibility, one connected with the offer of conversion and life."
The Church's Confession of Faith: A Catholic Catechism for Adults (San Francisco: Ignatius Press, 1987), p. 346.
For two preeminent Catholic theologians, you can check out Karl Rahner's Foundations of Christian Faith (New York: Crossroad, 1984), pp. 90ff and the entire book by Hans Urs Von Bathasar on the subject,
Dare We Hope That All Men Be Saved? with a Short Discourse on Hell (San Francisco: Ignatius Press, 2014).
That's right. Sort of.
For one thing, I wasn't talking about Eastern Orthodoxy or Roman Catholicism, both of which still hold to that idea of there being only one true church--theirs. You quoted me making a reference to Anglicanism, but Anglicans don't do that. And Universalism has nothing to do with it in any case. Not with Catholics, Orthodox Christians, or Anglicans.
I thought your post was a bit ambiguous in its implication regarding Catholicism and Orthodoxy. And I should say, although it's a minor point of clarification, it's still substantive and important to note that "subsists in" is weaker than "is" within the following statement from Vatican II:
This Church constituted and organized in the world as a society,
subsists in the Catholic Church, which is governed by the successor of Peter and by the Bishops in communion with him, although many elements of sanctification and of truth are found outside of its visible structure. (
Lumen Gentium, 8, emphasis mine)
I'm unclear as to how universalism wouldn't be "on point." If universalism were true, there would be no such thing as
extra ecclesiam nulla salus. That would be a meaningless doctrine itself. The most that one could claim for her particular communion would be something like, "we have the
fullness of the Christian faith over here," given universalism. But, I'm not trying to drag us into such a discussion...just another little point of clarification.
