Christian Formation
Christian formation is the lifelong process by which a person is shaped into the image of Christ — not through information alone, but through practiced habits, community, and the work of the Holy Spirit.
What Is Christian Formation?
Christian formation is the answer to a question most serious Christians eventually confront: why don't I change?
You believe the right things. You attend church. You pray, at least sometimes. And yet the man in the mirror — short-tempered with his kids, avoidant of hard conversations, quietly enslaved to his phone — looks much the same as he did five years ago. Maybe ten.
Christian formation is the theological and practical framework for what it actually takes to become different.
The phrase itself is relatively recent in popular use, but the reality it names is ancient. The early church called it theosis — being made partakers of the divine nature (2 Peter 1:4). The medieval tradition spoke of the via purgativa, illuminativa, and unitiva — stages of purification, illumination, and union. The Puritans wrote extensively about mortification and vivification — the killing of sin and the cultivation of virtue. Different languages, same conviction: transformation is the goal, and it requires more than agreeing with a set of propositions.
Formation vs. Information
Dallas Willard drew a distinction that cuts to the heart of the problem: most of contemporary Christianity is aimed at decisions, not disciples.
The evangelistic model optimizes for a moment of conversion — the prayer, the hand raised, the card signed. There is nothing wrong with conversion. But a Christianity organized entirely around getting people over a decision threshold has very little to say about what happens next. It produces, in Willard's phrase, "bar-code Christians" — people who have been scanned in, but not transformed.
Formation takes a different view. It assumes that a human being is not changed primarily by information — by knowing more theology, hearing more sermons, reading more books. A person is changed by practice, by repeated action that reshapes desire and habit at a level deeper than conscious decision.
The habits you repeat form you. The question is whether you are being formed intentionally or by default.
The Role of Spiritual Disciplines
Formation is not self-improvement. It is not willpower applied to the project of becoming a better person. It is, at its core, dependent on the Holy Spirit — "It is God who works in you to will and to act" (Philippians 2:13).
But God typically works through means. And the primary means the tradition has identified are spiritual disciplines — practiced habits that put us in a position to receive what only grace can give.
These include:
- Prayer — not as a technique for getting things from God, but as a daily practice of communion and dependence
- Scripture reading — not as information transfer, but as formation by a text that reads us as much as we read it
- Fasting — a practice that trains desire by denying the body its automatic claims
- The Examen — reflective review of the day that builds honest self-knowledge in God's presence
- Sabbath — a weekly surrender of control, a refusal to be defined by productivity
- Community — the unavoidable formation that happens when we commit to people who are different from us and refuse to leave when it gets hard
No single practice is magic. Together, practiced consistently over years, they shape a person.
Why Men Neglect Formation
Most men are not failing to grow because they don't care. They are failing because they have no structure.
The men who do grow tend to have one thing in common: they have regular practices that are non-negotiable. They don't wait until they feel like praying. They don't read Scripture only when inspired. They have built, over time, a daily structure that does its work whether or not they feel it doing its work.
This is not legalism. Legalism earns. Structure receives. The difference is everything.
Formation and the Pistis App
Pistis is built on a straightforward conviction: most Christian men need less content and more structure. The app is not a devotional reader or a podcast or a theological encyclopedia. It is a daily formation loop — four steps, completed before your apps unlock, every day.
The loop is the structure. The structure is the formation. Over time, the formation is the man.
