If your understanding of 1 John is correct it contradicts Romans 6:23. The Bible won’t contradict itself as God doesn’t contradict Himself.
I can just as easily say that if your understanding of Romans 6:23 is correct then it contradicts 1 John.
What you’ve just done is demonstrated is that the Holy Grail of Protestantism, Sola Scriptura, can’t stand. It requires either the refusal to interpret it at all, in which case apparently contradictory verses like this leave the reader in a state of utter confusion, or an authority whose interpretation can be relied upon.
I’ve come to the firm conclusion that that authority is the Roman Catholic Church. You’ve come to a different conclusion.
But this is going nowhere. I’ve repeatedly explained Catholic beliefs and supported them with Scripture. And rather than engage the points I’ve made you simply say I’m wrong. The most you do to engage the points I make is to quote another verse without any discussion. This last exchange is a perfect example. I support my point with a quote and you shoot back another quote that appears on the surface to contradict it, without any discussion to explain from your point of view why your quote either trumps mine or why they don’t really contradict each other.
I conclude that you got nothin’ more than a few Bible bullets you like to shoot at your favorite Catholic targets. You seem to think that making a glancing blow against a stationary target in a climate controlled shooting range is equivalent to taking down a bear in the wilderness of Alaska. You refuse to engage in any substantive and deep discussion of what you claim to be true. And when I make a good point that challenges you, you simply ignore it and move to a different target.
So I wish you well and choose to disengage from this conversation.
