In “The Interesting Narrative of the Life of Olaudah Equiano” the Bible was used frequently by Equiano and besides his religious convictions, it served a much more powerful purpose. While he was in the Ætna, Daniel Queen,
He taught me to shave and dress hair a little, and also to read in the Bible, explaining many passages to me, which I did not comprehend. I was wonderfully surprised to see the laws and rules of my country written almost exactly here; a circumstance which I believe tended to impress our manners and customs more deeply on my memory. (Chap. IV)
While I know this is not a direct reference to content within the Bible, the two different times of his life, he bonds through the Bible. This is a huge step within his narrative, and he does so various times, Equiano wanted to depict his life before slavery in terms that everyone would understand. Merely mentioning his past, could have led to misconceptions about how his life in slavery was better off. By recalling his country through the laws and rules of the Bible he is clearly stating that neither his people or him lived without purpose. They (his people) much like slaveholders followed similar life ideals just in different ways.
He also presented this idea after stating the kindness of Queen, trying to make the connection as amicable as possible. Somehow saying that a father figure of sorts, taught him the likeness between his home and the Biblical ideas. Besides that, there are many ways that one could interpret this connection, but I choose to believe that in some way Equiano alluded to his home being holy. While in one place they read holy scripture, at home they lived they practiced it within their laws and rules. Therefore, stating that since he had been ingrained with these ideals before having read them, he himself was able to live a holier life.
