You are correct on a few points.
It is not a building of stone, but a building on His Apostles teachings.
You are correct about demoniations, which did not exist prior to 1500 AD.
It is when denominations split apart what was already ordained that causes the confusion.
One must ask.....which came first; The Teachings from the Apostles, or the letters they wrote later?
And who has been left to discern the letters?
WE know the letters were written to the first 'priests' or rather 'disciples' that the Apostles were teaching.
Note; the Epistles are instructions to the Churches already established. Correct?
You are very clever. Yes, this is true.
But who has the first truths is what we should truly be in search of.
This becomes a difficult task when one man says the Bible means this, and another breaks off and says it means that. Would you agree?
So therefore man cannot be the authority of such Testaments. They are fallible and each one may feel it means one thing, and the other will totally disgree. Sad truly.
Love the Nicene Creed.
Jesus was all of that and more.
Jesus left His ppl a truth to follow, with which gives mankind graces abundantly, because He is all Mercy.
And yet, He is all just too.
So, we have to dig up research, and see what exactly was taught, not only by the Apostles themselves in the Epistles, because they were Inspired, but also because they taught prior to those writings...so what did they teach?
The early Christians who were taught by the Apostles, knew definitively what they were teaching.
There were 7 sacraments given, all are in the Bible, but moreso these sacraments warrant graces that help us succeed in our struggles on earth. Jesus is always good, and He knew our struggles b4 He ascended.
He did not leave us orphaned. He promised to be with us until the end of time.
So, is He with us, and did He leave us salvavic measures outside the Bible?
The Apostles taught the sacraments, and used them.
All of which aid us on our journey home. That is where we all desire to go, I believe I can assume such.
Would the Lord, filled with utter Love and Mercy leave His sheep unattended for 30 or 40 years? The NT, Epistles, were not even written while the first followers were learning.
He sent the truths in the Apostles, who taught the truths. NOT all of which were recorded by their very selves, but also recorded within their first Churches by their pupils.
Do you know anything about the sacraments and how they can be defined in the Bible?
