“You can sometimes tell by the fruits of their lives, but in the end, only God knows.”
I was accused earlier in this thread of being haughty, arrogant, and dismissive. Answers such as yours in response to the question as to whether Catholics are Christians are even more deserving of such description.
Are you a Christian? Are you and God in agreement on that point? How would I know?
Yes, I am a Christian. I received Christ into my life forty years ago. People who know us, know that we are Christians. Our lives reflect it. Of course you wouldn’t know because you don’t know me. Yes, God and I are in agreement. I have the assurance that I am born again and will live with Christ for all eternally. My husband, brought up Catholic, also now has that assurance.
Not all Catholics are Christian. Not all church going protestants are Christians. It’s what they’ve done with Christ that makes that difference.
