The concept of excommunication has been present in many religions or organizations over the years. Excommunication, as defined, is the act of expelling someone from an organization, religion or society; it is, basically, a punishment or penalty for certain actions or beliefs. Antonyms for excommunication can be words such as acceptance or inclusion, as these refer to the opposite concept of being allowed or embraced within a group or society. Other antonyms could be integration, admission, or welcome, all conveying the idea of being welcomed and accepted instead of being ostracized or punished. Ultimately, antonyms for excommunication are words that relate to inclusion and acceptance rather than isolation and rejection.
