I could not agree more.
The Catholic Church produced the Bible. The Bible didn’t produce the Catholic Church. It is a document of and by the Church.
Are you stating the Septuigent (3rd century BC) was created by Catholics? Why don't you explain yourself and/or show us your proofs. Because on the face of it, that is just a plain stupid statement.
Is this a demand from one of the churches of men?
Or is this a demand from an individual bereft from even a church?
Regardless; we of the Church of Christ will attempt our best to convince even through layers of solid bone.
I am sure he is not. The Old Testament was obviously a product of inspired Hebrew writers. The Holy Scripture in its entirety, however, is a part of the revelation received by the Catholic Church; Catholic men wrote the books of the New Testament and the Christian Canon was determined by the fathers of the Catholic Church, as well as the Christian creeds, the liturgy, and the theology.
Of course, the same can be said of the Orthodox Church, and in some part of the pre-Chalcedon Churches of the East, as the Orthodox Church and the Catholic Church were one and the same through that formative period, and the pre-Chalcedon Churches for the substantial part of it.
