Greetings! My name is Josh, and I am an inquirer of the Greek Orthodox faith. I am under the impression that the Church not only recognizes every book of the Tanakh (with certain additions) as canon, but that it also recognizes several other books (namely, the First (or Third) Book of Ezra, the Book of Tobit, the Book of Judith, the First, Second, and Third Books of the Maccabees, the Wisdom of Solomon, the Wisdom of Joshua (the Son of Sirach), the Book of Baruch, and the Epistle of Jeremiah) as canonical parts of the Old Testament. If so, are the Second (or Fourth) Book of Ezra and the Fourth Book of the Maccabees also considered canon? Also, what do you believe about the Protoevangelium of Saint James? As for Holy Tradition, what constitutes it? I am familiar with the Ecumenical Councils, but I want to know if there are any other sources.
