It took me 2 years… and to be honest still counting, to realize no man on earth can ever give me that type of assurance, the type of assurance I think you are looking for… The type of guarantee only God can give. The assurance that tells us, we are with God.
There’s definite truth to that. In the final analysis, it is God who saves, not man.
How can any man, even a man with authority give that to us?
Because Jesus gave it to him:
Jesus said to him, "And so I say to you, you are Peter, and upon this rock I will build my church, and the gates of the netherworld shall not prevail against it. I will give you the keys to the kingdom of heaven. Whatever you bind on earth shall be bound in heaven; and whatever you loose on earth shall be loosed in heaven.”
Jesus literally gave Peter the proxy of divine authority. When Peter decided that there should be apostolic succession (see Acts 1:15-26), boom – there it was! Decreed by Peter, bound on earth, and therefore, bound in heaven.
This notion of “binding and loosing” speaks – in a context that stretches back to the ancient Kingdom of David – to the power to proclaim authoritative teaching. So, again, “bound/loosed on earth” == “bound/loosed in heaven.” That’s why it’s so powerful! Jesus literally gave this kind of authority, so if the Church teaches it, then it is authoritatively true (and, if a matter of doctrine or morals taught as ‘infallible’, then it’s ‘infallible’, because Jesus promised that protection
to the Church through His apostles. Not to other churches yet to be founded, and not to individuals.
I’m not interpreting scripture, leading myself… I pray, ask (people

) pray again.
Right. And by what authority do those people speak?
(To be fair, you should ask “Gorgias, why do
you have authority to tell me this?”, right? And my answer would be, “I’m not the origin of this doctrine, the Church Jesus founded and its apostolic leadership teaches this, and teaches it authoritatively!”)
