i think you have every right to question the canon, since it was determined by fallible humans, using the best of thier intellect, and guided along by their subconscious biases, to determine the true canon. i personally use the NRSV with the apocrypha and enjoy reading all the books. Also, i’ve enjoyed reading some of the various other books that were read by the earliest Christians, and even some of the psuedo literature. There’s a link on my blog site to an old website i developed which is still up and running. It’s called Lord Adonai. You can download a free bible program (theophilos) along with various books and a collection of extra-biblical texts. It’s all free, and this is not a spam. My blog is www.exploretherabbithole.blogspot.com. Though i enjoy reading this literature, i do not consider it scripture, though there is some very inspiring and godly words within the texts. If you’re serious about this, i think you would need to explore the background of each text you read and determine for yourself whether you think it to be scripture. Look into the qualities that were used to determine the texts we do consider scripture, such as inspiring to holiness, close connection to an apostle (which you may not agree with), reliable in content, etc. Also, you would need to make sure there aren’t blatant contradictions. i believe texts like the Maccabees were discarded because they had some illusions to the idea of purgatory and praying to angels. Is there anything that contradicts clear statements in other letters that you DO consider scripture? There certainly isn’t anything saying that we can’t question the canon, but we certainly must do our homework if we do.
