I’ve no trouble with that, actually. The RCIA Moderator made it clear that she was talking about salvation…getting to heaven. To her, all christian churches are valid paths to salvation and heaven
Now it just so happens that, for the last 3 weeks, our daily RCIA classes at
catechismclass.com have opened with quotations from the current Official Catechism, back up by biblical passages, that no one gets to Heaven except through Jesus and the one and only Church he established, the Roman Catholic Church
My basic attitude in RCIA class is summed up in an old AA prayer; “God, keep your arm around my shoulder and your hand over my mouth.” This seemed to be one of those times when it was best for me to stay silent. If I was wrong, I apologize.
