I do understand it.
The issue isn't understanding it, it's believing it as taught by the RCC.
I simply don't believe the legitimacy of the claim because of lack of Scriptural support for it.
“I do understand it.”
Ok, then why aren’t you familiar with the Acts 1 argument?
“it’s believing it as taught by the RCC.”
It’s a core teaching. This isn’t something that would be off to the side.
“I simply don’t believe the legitimacy of the claim because of lack of Scriptural support for it.”
What do you want, an account for how St. Peter and the popes were elected?
Would that be sufficient scriptural evidence?
