Careful, you may hurt yourself.
Let's say you read the bible and expositions on it. You understand more and more about the Christian theology. But you don't go to church, nor believe in any rituals and superstition. So you're not a religious Christian even though you continue to express a strong and growing interest in Christian theology.
See, that was easy.
Yes, that is called a non-Christian scholar of Christian theology. I've already said this. What you are describing is someone who is not a Christian, but has an academic interest in Christian doctrines.
They are Christian because they accept the trinity, redemption by Christ, salvation through faith.
That isn't what you said.
"But you don't go to church, nor believe in any rituals and superstition. So you're not a religious Christian even though you continue to express a strong and growing interest in Christian theology."
That is not a Christian.
You might want to check which subforum you're in. OBOB is not a modernist place where Christianity is some mamby-pamby whatever-you-want-it-to-be relativist nonsense. I may have my disagreements with Catholicism, but they certainly got that part right.
So a person isn't Christian even if he believes in Christ? must we necessarily go to church or follow specific rituals in order to be counted as one?
You aren't much of a follower of Christ if you "believe" and yet refuse to be joined to his Church and participate in the Sacraments. So, I'd say your answer is "no, a person isn't" and "yes, you have to".
According to Christ, yes. It's not just enough to believe even demons believe as Christ said we have to go beyond that by doing as He commands. Moreover James through the Holy Spirit says that we must show works along with our faith. There is much more to being a Christian than beliefSo a person isn't Christian even if he believes in Christ? must we necessarily go to church or follow specific rituals in order to be counted as one?
