The article barely touches on this subject, but the sentiment is nonetheless correct.

The problem with using an AI to write something so intimate and context-specific is that it cannot perform as the priest's highest and best abstraction. Instead, it will slavishly follow instructions and risk tunnelling the priest into a worldview and message that subtly betrays his congregation.

I recently wrote about how modern legal tech stacks can do the same using the infamous Digital Research / IBM non-disclosure agreement as an example: https://tritium.legal/blog/redline

If we habitually reduce our context to the lowest-common window ingestible by an AI, yes we may lose a bit of humanity, but more importantly we'll just do a worse job.
