The Calvinist says, “The Old Testament in Hebrew (which was the native language of the people of God of old,) and the New Testament in Greek, (which at the time of the writing of it was most generally known to the nations) being immediately inspired by God, and by his singular care and providence kept pure in all ages, are therefore authentic”.
The first error the Calvinist makes is to claim that because God initially used Hebrew and Greek, that those languages are somehow more specially, or are the specific method of conveying the truth to the world.
That was certainly not the view of King James Bible translators, who said that the Scripture in English was the Word of God.
