«اِلْكِنِيسَهْ تِعْرَفْ أَهْلَهَا»

A place that people visit again and again comes to know them, and anyone who truly belongs is recognized simply through that steady, familiar presence. Membership shows itself in habit and history rather than in claims. The church is only an image for such a place, not a comment on Christians or any religious community.

The saying is turned against an outsider who attaches himself to a group and assumes his intrusion goes unnoticed. It warns that such a person is seen for what he is, since the genuine members are already known.

Use it about a newcomer or hanger-on who poses as a long-standing member of a group, family, or circle, believing the act is convincing. It remarks, often wryly, that the insiders can tell the difference and are not fooled. Aimed at someone present, its mild rebuke can sound pointed.
