“What was your question again?”
If a Catholic faithfully follows Catholic doctrine for his or her entire life, is that person a Christian?
“If a Catholic faithfully follows Catholic doctrine for his or her entire life, is that person a Christian?”
In direct answer to your question, Catholic doctrine does not save one’s soul, nor does any other doctrine. The way to be saved is to follow Jesus. He is, by His own admission, “THE way, THE truth and THE life.” By His own words there is no other way to salvation.
Like it says in Romans:
9That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.
10For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.
11For the scripture saith, Whosoever believeth on him shall not be ashamed.
12For there is no difference between the Jew and the Greek: for the same Lord over all is rich unto all that call upon him.
13For whosoever shall call upon the name of the Lord shall be saved.
Now if you ask me do I believe those words, then yes, I do. If you ask me to pronounce on anyone else salvation or condemnation you’re barking up the wrong tree, Spot. I believe that God and Jesus are who the Bible say they are. I believe that anyone who trusts in a doctrine, be they Catholic or otherwise, and that is what they have put their trust in are in danger of being separated from God for eternity. But I have no right one way or the other to say their heart is not right with God because I don’t know the full depth of their beliefs. Part of your problem is in the phrasing of your question. Most (maybe not all) Christians do not believe that a doctrine saves you but that you are saved by faith. Following a doctrine is more closely akin to salvation by works and the Bible is also clear that is not the way to heaven.
The following verses in Romans go on to say, “How can they hear without a preacher.” It’s not up to the preacher to save anyone else any more than it is up to you to argue someone’s Christianity. The only thing the preacher can even do is put the Word out there. He does not save souls.
You see, it’s like with the defense of our belief in the Biblical account of Creation; we can speak volumes and answer to the best of our ability and if you do not like the answer you will simply claim the question has been avoided. You just rephrase the questions in an attempt to trap someone and confuse the issue.
To quote a line that was said sarcastically the first time, “Surely, you have a dizzying intellect.”
