Michael W. Holmes would certainly be considered a credible source and a reliable author. Dr. Holmes has degrees, including a Ph.D, from multiple religious institutions and has written countless articles and books relating to the Bible or its subject matter. He is particularly fluent in the New Testament. On top of this, Dr. Holmes teaches Biblical Studies and Early Christianity at Bethel University, so he constantly takes in and produces media related to the Bible. Of course, these accolades do not mean you should take his word 10o% of the time, however Dr. Holmes is clearly a scholar and someone who is up to date on the Bible and is knowledgeable in the field having studied for many years.
In researching through Google, I was able to find someone who is most certainly a reputable and distinguished source for the Old Testament – James L. Kugel. In particular he is a specialist in the Old Testament and the Dead Sea Scrolls. Dr. James Kugel has taught at a few Universities, including teaching Hebrew Literature at Harvard University for twenty-one years. Dr. Kugel currently teaches at Bar Ilan University in Israel. He has also written over eighty research articles on the Bible and fifteen different books. While Dr. Kugel is a very astute scholar of the Bible, humans are not without their biases. He is a believing Orthodox Jew, which could mean that he interprets and sees things in the Old Testament differently to other sects of Christianity. Despite these biases however, his works and his books are renowned by professionals within in the field.
Throughout the lesson, I have learned that even the most astute scholars can have their biases towards a topic, especially one as controversial as religion. Every human holds biases, whether they be conscious or unconscious. You need to do fervent research and make sure that these biases do not conflict with the specific article/piece of media, you need to cross check with professionals who hold different biases. Trusting one person with all of your heart is not good from an academic standpoint, you must see what the consensus is from multiple points of view to get the full picture.
