You recognize that what the Church put together by the end of the 4th century represents the scriptures. On what do you base your trust that the Church really did put together a Christian canon that you worship?
Do you not think that the same Church whose expertise or Holy Spirit helped put together the Christian Canon is at the same time not the authority to recognize and interpret the same scriptures it has selected as Canon?
And on what do you base your insinuation that the Church somehow 'lost' that authority over time?
The quality control is contained in the liturgy that goes back practically to the beginning; the documents describing practices and beliefs; the earliest writings of Apostolic Fathers—people who were ordained by living Apostles, and all those who followed them. They all profess one and the same catholic and orthodox faith once delivered and always believed.
“You recognize that what the Church put together by the end of the 4th century represents the scriptures”
Many churches had already accepted the books included in canon by the various church leaders in the councils so the councils did not put together the scriptures but simply ratified what the churches were already accepting as inspired and authentic.
“In this sense, we can understand possible imperfections in the books of the Bible, since they are the result of the cooperation between the all-perfect and perfecting Divine Author, the Spirit, and the imperfect human author.
Nothing human is perfect, including the Bible, which is the end product of human cooperation with the divine Spirit.”
That’s an incredible statement for it puts in question the perfection of Jesus since by your theology, his conception and birth was the result of divine-human cooperation.
