Richard mentions hearing the Prior speak about Gabriel, noting that the Prior sometimes appeared to confuse Gabriel with the Pope. This suggests that the Prior might hold Gabriel in high regard or see him as someone of great importance, perhaps even with spiritual or leadership qualities comparable to the Pope.
By highlighting this confusion, Richard hints at the significant role Gabriel plays within their context, and possibly the influence or respect Gabriel commands. It also reflects on the perceptions and relationships among the characters in the story, illustrating how individuals can be viewed in lofty, almost divine terms.
