Formation is the ordered shape of a body — military or ecclesial — and the deliberate discipline that produces it. Paul speaks of "Christ being formed in you" (Galatians 4:19) — the apostle in labor-pains for the church until the Lord’s shape is visible in the saints. He also names the goal: "for whom he did foreknow, he also did predestinate to be conformed to the image of his Son" (Romans 8:29). Christian spiritual formation is therefore not vague self-improvement; it is the long shaping by Word, Spirit, ordinary providence, and intentional discipline into the shape of Christ. It happens through Scripture, sacrament, prayer, fellowship, fasting, and trial. The saint does not produce the form; he submits to its making.
The act of forming; the manner in which a body is composed; the ordered shape produced by discipline.
FORMATION, n. The act of forming or making; the manner of formation; the structure or arrangement.
Christian formation is the long process by which Christ is formed in the believer (Gal 4:19) and the believer is conformed to Christ's image (Rom 8:29). It happens by Word, Spirit, sacrament, providence, and community over years.
Galatians 4:19 — "My little children, of whom I travail in birth again until Christ be formed in you."
Romans 8:29 — "Whom he did foreknow, he also did predestinate to be conformed to the image of his Son."
2 Corinthians 3:18 — "We all, with open face beholding as in a glass the glory of the Lord, are changed into the same image from glory to glory."
Ephesians 4:13 — "Till we all come... unto a perfect man, unto the measure of the stature of the fulness of Christ."
Modern Christianity often expects formation to be quick and curated; Scripture treats it as long, painful, and Spirit-paced.
Galatians 4:19 uses the language of childbirth: Paul travails in birth again until Christ is formed. Formation is slow, costly to the discipler, and accomplished by the Spirit working through ordinary means — not by event, not by curriculum.
The household, church, and individual formation share this rhythm: Word read, sacrament received, prayer practiced, providence accepted, community endured. Across years. There is no formation without the long arc.
Greek morphoō (to form, shape) and summorphos (conformed) underlie the New Testament concept.
Greek morphoō — to form, shape; the verb of Galatians 4:19.
Greek summorphos — conformed, sharing the same form; Romans 8:29.
"Formation is slow; do not expect a curriculum to do it."
"Christ is formed in the saint by Word, Spirit, and years."
"There is no formation without the long arc."
