What is an oath? FYI: This discussion is focused on the United States. The information was researched using AI. (I like to be honest even though I didn't take an oath!) Let's start with religion. Religious leaders do not take a single universal oath, but many do take some form of oath, vow, or pledge depending on their faith tradition, denomination, and role. Some traditions require very formal vows; others rely on informal commitments or ordination promises. ✝️ Christianity
