Why “pseudolatry” is a great word
PSEUDOLATRY — [Noun] The practice of false or spurious worship. From the combining form pseudo- (from Greek ψευδής, meaning "false") and -latry (from Greek -λατρεία, from λατρεία, meaning "worship"). First attested in 1879. Unlike idolatry, which consecrates a false god, or orthodoxy, which anchors itself in authorized belief, pseudolatry is the hollow performance of faith. It is the politician crossing himself for the cameras, the creed recited with eyes fixed on the congregation, the polished donation made for the public ledger—the liturgy of a heart that has quietly, definitively, left the building.
Etymology
From pseudo- + -latry.
