Very good. So which of those tenets does the Catholic not follow?
I’m sorry to belabor this but Catholicism takes a beating on triple G’s posts and I want to see why the disconnect between they and other Christians.
If they strictly follow the teaching of the Church that the sacrifice of Jesus gives grace to then allow the individual to earn merit towards salvation, then they are trusting on Christ by grace alone.
In fact, the Church teaches that it is presumptious to claim that you "know" you are saved. That rejects the notion that a person is born again at a particular point in time, and then has the assurance of being blood bought and born again. As such, people are to continually perform meritorious deeds so as to "move toward" heaven, after a period of time in purgatory.
If a Catholic rejects these teachings and believes what the Bible says (and many have and do), then they are born again and Christians.
