In 367, Athanasius of Alexandria (A.D. 296-373), the most prominent theologian of the fourth century who served as bishop of Alexandria wrote the following in his Thirty-Ninth Festal Epistle commonly referred to as his “Easter Letter.”  His was the first official pronouncement of a list of canonical books identical with our present-day list. Athanasius’ list was not a hierarchical decision but a widely acknowledged recognition that the list contained the books the church already recognized as authoritative. After the list he declares,
“These are the fountains of salvation, that he who thirsts may be satisfied with the living words they contain. In these alone the teaching of godliness is proclaimed. Let no one add to these; let nothing be taken away from them. For concerning these the Lord put to shame the Sadducees, and said, Ye do err, not knowing the Scriptures. And he reproved the Jews, saying, Search the Scriptures, for these are they that testify of me.”
