There are several issues in your text, I hope you don’t mind if I separate some.
[quote=nkelly] I’ve been thinking about the Church’s teaching on damnation and death in mortal sin and the terrible implication of this.
I don’t mean to sound judgmental but it sounds like you’re either confusing what’s written in the CCC or taking it out of context. The teaching of the Church is not as harsh as you are portraying.
I’d start with the CCC Para 413-421, these are the summary of the fall of man, which introduced sin into the world. Yes, if you are in mortal sin and willfully reject God and die, you’re going to hell, but if you understand what this implies how could a rational person willfully do this?
[quote=nkelly] This teaching automatically condemns all non-catholics to hell because they’re by definition not baptized and can’t therefore avail of Holy Communion and confession
No teaching of the Church that I have read “automatically” does anything. It doesn’t work that way. First of all it isn’t a “catholic versus Non Catholic” issue, please note the verbiage of CCC paragraph 421 below, it says “Christians” not Catholics.
[quote=CCC] 421 Christians believe that “the world has been established and kept in being by the Creator’s love; has fallen into slavery to sin but has been set free by Christ, crucified and risen to break the power of the evil one. . .” (GS 2 § 2).
[quote=nkelly] given that the chances are that 99.999% of us have commited mortal sins at some point in our lives.
No, you can’t commit a mortal sin accidentally or carelessly, it is a willing knowledgeable rejection, it isn’t a mistake, and you must know fully well that it is a sin, of the ramifications of the action and take it in disobedience of Gods will.
[quote=CCC] 1872 Sin is an act contrary to reason. It wounds man’s nature and injures human solidarity.
I REALLY doubt 99.99% of people willfully, knowledgably, intentionally and completely reject God.
[quote=CCC] 1874 To choose deliberately - that is, both knowing it and willing it - something gravely contrary to the divine law and to the ultimate end of man is to commit a mortal sin. This destroys in us the charity without which eternal beatitude is impossible. Unrepented, it brings eternal death.
This was one of Martin Luther’s’ problems, he thought every little mistake he made was a mortal sin, it isn’t.
[quote=CCC] 1871 Sin is an utterance, a deed, or a desire contrary to the eternal law (St. Augustine, Faust 22:PL 42, 418). It is an offense against God. It rises up against God in a disobedience contrary to the obedience of Christ.
Can I suggest you review the Catechism of the Catholic Church a little more? Especially:
Chapter 1, article 8; Chapter 2; and Chapter 3.
