1QS (Community Rule) VI–VII
Whoever has uttered the Most Venerable Name even though frivolously, or as a result of shock or any other reason, shall be dismissed and shall return no more to the Council of the Community.
Second Temple communities already practiced graded discipline: rebuke, temporary exclusion, and in some cases expulsion. That does not make Qumran the Church. It does show that ‘belonging without boundaries’ is a modern demand, not an ancient Christian or Jewish one.
