Pseudonymity and the Apostle Patterson

One of the more challenging things I face as I try to present my historical-critical-mystical perspective on scripture to others is explaining pseudonymous texts.

For pointed example, only seven of the texts in the Bible that are purportedly written by the Apostle Paul are likely to have been written by him. The remainder are by individuals writing in his name, who are doing so for a range of different reasons. It's to convey his theology, or to use his authority to bolster their own, or to give provenance to a message.

But we have trouble with this, in our modern ownership-society sensibilities. An author is pretending to be someone else? Piggybacking off of another's name? It feels like plagiarism. Like cheating. Like it's faintly nefarious, a copyright violation.
