Single-faith refers to the adherence to, and the exclusive practice of, one particular religious belief system.
It encompasses the doctrines, rituals, moral codes, and community aspects associated with that specific faith, and it typically excludes or actively discourages the acceptance or practice of other religions.
The concept can apply to individuals, communities, or even entire societies where a dominant religious tradition shapes cultural norms, laws, and social structures.
Historically, single-faith societies have ranged from those fostering tolerance and understanding to those exhibiting religious persecution and intolerance towards dissenting beliefs.
