The Scripture is not infallible…infallibility means incapable of committing error…an action word…on a man can be fallible or infallible.
Do you think Catholic are not Christians?
If someone believes in the gospel that Rome teaches, then no, I don’t believe they are a Christian.
I am puzzled…should not there be only one definition?
There should be but there isn’t. Everyone in America seems to think they are Christians. Just look at any Gallop or Barna poll. Anywhere from 70% to 80% of the people polled think they are Christians. In Matt 7, there are
many who say to God on judgment day that they knew Him. He tells those
many to “Depart from Me, I never knew you.” Jesus said there are
many on the wide road on their way to hell. He said there are
few on the narrow road which leads to heaven. Last time I checked, many is more than few. A simple math calculation tells you that at the bare minimum, 51% are on their way to hell. At the bare minimum, 20% to 30% are deceived based on the polls.
Calling yourself a Christian is no more valuable than calling yourself a car just because you are standing in a garage.
And who do you think were the first Christians?
The word “Christian” came from some believers in Antioch. It simply came to recognize those who were true followers of Christ in the NT. True believers in the OT were no less born again, they just weren’t “called” Christians. The bottom line is; you are either a true believer, or you aren’t.
