We never canceled other religious names in our calendar, including the months named after Roman gods or the days of the week named after Nordic / Celtic gods.

Recognizing Jesus Christ as lord obviously presents some theological issues to non-christians. Saying Wednesday doesn't have the same issue of recognizing Odin's divinity.
