Okay - define "church fathers." Because if you include Matthew, Mark, Luke, John et al as "church fathers" - which I do not believe is the normal use of the term - then okay. But the "church fathers" I am familiar with did not write the Old or New Testaments. So although they had their place in God's plan, they certainly do not match the stature of the writers of the OT and NT.
Church Fathers were the disciples of the Apostles and the dispciples of disciples etc ... They were the teachers and confessors and leaders of the Church. They assembled and selected the books of the New Testament. They defined the dogmas of the Faith like Holy Trinity, Divinity of Christ, the unity of two Natures of Christ, the Divinity of Holy Spirit etc ... The Holy Spirit guided them same way as He guided the Prophets of the Old Testament.
Luther and Calvin attempted to restore the original Church from the Scriptures and they removed books which did not fit their doctrines.
