📖 Biblical Definition
Esprit de corps is the shared morale and identity of those who belong to a common body. The Marine knows it as the love that binds the unit; the saint knows it as the body-of-Christ love Paul commands. One body, one Spirit, one hope of your calling, one Lord, one faith, one baptism, one God and Father of all — the church's esprit de corps is theological, but no less real for being grounded in doctrine.
📜 Webster 1828 Definition
(French.) The common spirit pervading the members of a body; collective loyalty, devotion, and morale.

Webster 1828 does not enter esprit de corps; the phrase came into wider English use through the U.S. military in the 19th century, especially the Marines.
The biblical equivalent is koinonia (fellowship) under the headship of Christ — not merely camaraderie, but a covenantal sharing of the same Spirit, the same Lord, and the same destiny.
📖 Key Scripture
Ephesians 4:4 — "There is one body, and one Spirit, even as ye are called in one hope of your calling."
1 Corinthians 12:25 — "There should be no schism in the body; but that the members should have the same care one for another."
Philippians 1:27 — "Stand fast in one spirit, with one mind striving together for the faith of the gospel."
Acts 4:32 — "And the multitude of them that believed were of one heart and of one soul."
⚠️ Modern Corruption
Modern individualistic Christianity has thinned esprit de corps to an event-feeling; Scripture treats it as the daily atmosphere of a body that lives or dies together.

Acts 4:32 names the early church's atmosphere: of one heart and of one soul. They shared possessions because they had already shared identity. The morale was theological before it was sociological.
The Marine knows the principle: a fire team that loses cohesion does not survive. The church that loses esprit de corps does not survive either. Recovery is not by retreat-weekend programs; it is by repeated covenantal practice — same table, same Word, same Spirit, same fight.

Note: French esprit (spirit) plus corps (body) maps directly to the Pauline pair: one Spirit, one body.
