3JN 1:10

10 Oib azoi [(consequently)], if I come, I will remember his “ma'asim” [(works)] which he does, his bringing unjustified charges against us with lashon horah [(evil speech)]. And not being satisfied with performing these “mitzvot”, he even refuses to receive the Achim b'Moshiach, and, those intending to do so, he hinders and expels out of the kehillah.
