God is the final authority. He gave us the Bible. We are supposed to do what it says, both individually and corporately. The church has authority only insofar as it conforms to the Biblical standard.
I don’t really worry about it.
I don’t really worry about it.
Apostolic lineage is not necessary. I don’t really think Paul’s “model and example” here is relevant.
Are you infallible? Why should I believe you? You seem to think that infallibility is required before you believe anything. I don’t think you demand that the Catholic Church declare everything it teaches to be infallible, do you? There is only a small body of dogmas that have been infallibly declared, and I am not sure you all even agree on what is in that. Most Catholic teaching is at a lower level than infallibly declared.
Back to the Bible. If it says, “God is love”, and I say, "the Bible says,‘God is love’, my statement does not have to be infallible, does it? You can look and see that the Bible says that. I don’t regard infallibility as anything necessary. Maybe not even desirable.
Compare it against Scripture. How do I know you have the correct interpretation? Only because you say you do.
I don’t have any authority. Furthermore, Protestant pastors are known to frequently say things like, “Don’t just believe me - check what the Bible says.” But at the same time they will have a defense in depth of what they believe the Bible says. And a willingness to change should they be shown to be wrong.
Off-thread: we believe that Christ is truly and really present in and with and of the Communion elements, but not that there is an actual physical change. I am not getting that right, because it is very nuanced. From my own personal experience and that of others I know He is very much present in a very real way. If I remember correctly we meet him by faith. That meeting is a real meeting, not a hypothetical one, and things happen. But that is off thread.
I know a woman who after she was widowed for years tasted very warm salty wine and meaty bread when she took the elements - it was Jesus’ way of confirming His presence to her. I have no reason to doubt her. I have had things happen. Others have. Usually it is very very personal and is not discussed, because we look at Jesus and not after miracles. He has not abandoned the Protestants in our sacraments.
Truth,
God is the final authority, He gave us a Son, that built a Church, that was a mystery hidden for all ages and that Church produced a Bible…where does the book say that all must conform to the book.
What is believed is revealed and the Catechism contains what is believed through Scripture and Tradition.
The Trinity you accept was revealed and not necessarily discerned through Scripture, as evidenced by your Protestant offshoots, Jehovah Witness, Mormons and Oneness Pentacostals.
