To baptism “ultimately the answer is no”, then you provide caveats. I have to inject how the CC justifies infant baptism as a means to salvation. This tells me the CC believes Baptism is a mechanism to salvation. But I have been told by many Catholics (and even some non-Catholics) that if you are not baptized you can’t be saved.
The caveats are the reason the answer is no. Granted, the caveats are small and not likely; however, they do exist so therefore the answer is no. Baptism is a mechanism to salvation; however, it's not absolutely required, again, due to the caveats mentioned. Is it better to be baptized? Absolutely! Is it preferable to be baptized? Absolutely! Does baptism confer a special grace upon the person receiving it? Absolutely, and that's why we baptize our children.
To communion, again you are placing caveats. They are not *absolutely* required, but could be?
See above, same thing.
Even if we (all of us) do accept that the Catholic Church is THE Apostolic Church (the source church for all Christianity), which many don’t, is it acceptable that we be members of non-Catholic churches? I’ve had many tell me otherwise.
Acceptable? Well, no it's not acceptable, but it is tolerable. You are our "separated brothers in Christ". As long as you aren't swaying away from basic Trinitarian Christianity, then we consider you the Body of Christ. Distant cousins or something like that, but still family.
I like your answer here, but the problem I have with it is, if I sin and die before I have a chance for confession/repentance, what is my salvation status? You already know my view on this, that once you accept Christ as your savior you are saved at that moment.
Repentance stems first and foremost from the heart. The act of confessing is to seal that repentance and renewal with God's grace, a reciprocal act of love. If you die sorrowful for your sins, then the act of confession isn't necessary; however, it is better, preferable, and confers a special grace. Now, having said that, if you die having committed a sin that you knew was a sin and you were not sorry for it, then you're in trouble and your salvation might be at stake.
All other things are supposed to be natural changes in one’s life, but not requirements to ‘maintain’ one’s salvation. But I am in an effort to show that many Catholic do hold the view that if you don’t adhere to these ‘sacraments’ you are not saved; thus by inference stating they can claim to know the status of one’s salvation. You and Bird Dog have sort of stated otherwise; but I have enough personal experience to say it is widely believed that you must accept Christ, be baptized, receive communion routinely, go to confession, be a member of the Catholic Church… and not doing these things, you’re not saved.
How old are these Catholics? I ask because there are many that are still living in a pre-Vatican2 era. Vatican 2 was an ecumenical and teaching council of bishops from all over the world to come together to form new and different understandings of the doctrines of the Church. The council officially began on December 25, 1961 (only two generations ago). The doctrines stay the same, but over time our understanding of them differ. We do not understand things the same way we did in the 1st, 5th, 10th, or 15th centuries. (The Wiki article is good if you care to read it). As you can imagine, considering how many Catholics there are in the world, it is very difficult to re-catechize those who were raised pre-V2 hence the confusion.
But I don't want to beat this up too much because I adamantly reject anyone claiming they know the status of someone's salvation; unless that person openly admits they are an atheist and completely reject God.
Agreed.
And btw, Chuckt and those like him are the only ones who point fingers on this forum, this venue, this media. I guarantee you that the majority of Christian faithful on somd.com forums are majority Catholic, but as typical of Catholics they just want to practice their faith and be left alone. There are only a few who are willing and/or equipped to address people such as he. I was raised in various Protestant denominations and was exposed to Catholic households and never once was my salvation called into question by anyone UNTIL I became Catholic and it was then the persecution and finger pointing began by not only my own family but strangers as well. Although not exactly the same, my experience is somewhat similar to yours.
You go girl! But you may need to go to confession after
