You’ve had a lot of good answers so far, SpoiltVictorian.
I was asked, among other things, if I would say that someone who chose not to be baptized but “was a Christian in every other way” would go to hell. I didn’t have a good answer and so I ask you all:
- What do you do in these situations?
As a former poster said, I would reply that it is not my job to say who goes to hell; it is Jesus’ job. If they press you on it, say, “It’s not a cop-out; it is what my church teaches.”
- How would you answer the question posed to me?
Here is the Catechism. Note the part I made purple.
***“Outside the Church there is no salvation” ***
*
846 How are we to understand this affirmation, often repeated by the Church Fathers?335 Re-formulated positively, it means that all salvation comes from Christ the Head through the Church which is his Body: *
*Basing itself on Scripture and Tradition, the Council teaches that the Church, a pilgrim now on earth, is necessary for salvation: the one Christ is the mediator and the way of salvation; he is present to us in his body which is the Church. He himself explicitly asserted the necessity of faith and Baptism, and thereby affirmed at the same time the necessity of the Church which men enter through Baptism as through a door. Hence they could not be saved who, knowing that the Catholic Church was founded as necessary by God through Christ, would refuse either to enter it or to remain in it.336
- *847 This affirmation is not aimed at those who, through no fault of their own, do not know Christ and his Church: *
Those who, through no fault of their own, do not know the Gospel of Christ or his Church, but who nevertheless seek God with a sincere heart, and, moved by grace, try in their actions to do his will as they know it through the dictates of their conscience - those too may achieve eternal salvation.337
I like to charitably assume that the non-Catholic Christians I know do not know enough about Catholicism to reject it out of hand - and that, even if they do, there are circumstances that only Jesus knows about, that will see them saved.
- Finally, how do you explain the benefits of right doctrine vs. “90% cut-and-dry with the other 10% not being a big deal?”
(Don’t tell your classmates about the following paragraph.) That’s a funny statement in both meanings of “funny.”

A lot of the megachurches are loose on doctrine, so that they can remain “mega.” If they developed a firm doctrine, they’d get smaller and smaller as people disagreed with various points. That’s one of the problems with being Protestant!
OK, back to what to say…
How do they know *which *10% is not a big deal? Does this mean that they give more weight to some parts of Scripture than others?
(Most of the honest non-Catholic Christians I know have to say “yes” to that. But that is not the Catholic way.)
Does, for instance, “He who believes and is baptized will be saved; but he who does not believe will be condemned” (Mark 16:16 RSV) mean that Jesus doesn’t care if you are baptized? Is that also what Matt 28:19 means?
Here is an excellent article about reading Scripture. Since it is copyrighted, don’t hand out copies. In your case, I’d just make an outline of it and take it with me to refer to.
Good luck, and keep us posted!
God bless you,
