Virtue signaling is public moral display whose primary purpose is to advertise the virtue of the signaler, not to accomplish anything good. The term was coined in its current sense around 2015 but the behavior is ancient — and Jesus took direct aim at it. In the Sermon on the Mount, Jesus gave three case studies of how not to do religion: don't give alms "to be seen by men," don't pray "to be seen by men," don't fast "to be seen by men." Each time He uses the word hypocrite — Greek hypokrites, originally meaning "stage actor" — and says their reward is the public approval they sought. "They have their reward" (Matthew 6:2, 5, 16). God owes them nothing more. The modern equivalents are familiar: posting about causes without contributing; signing petitions that cost nothing; performing outrage at other people's sins; displaying lawn signs or social media banners as public declarations of team membership; lecturing others publicly while ignoring private duty; wearing the correct ribbon or profile-picture overlay. The phenomenon is not new; only the medium is. What Scripture teaches instead is quiet substance: "Let your light so shine before men, that they may see your good works and glorify your Father in heaven" (Matthew 5:16) — but this is about good works actually done, not advertised words. "Take heed that you do not do your charitable deeds before men, to be seen by them" (Matthew 6:1). The test of virtue is: would I still do it if no one ever knew? If yes, it is real virtue. If no, it is signaling. A world saturated in virtue signaling produces the exhaustion of moral inflation without the substance of moral change. The Christian answer is real obedience, often hidden, reported to no one but the Father who sees in secret.
