Concerning The True Care of Souls
The shepherd's sacred duty
Description
In 1538, Martin Bucer was the leading reformer of Strasbourg, a free imperial city that had thrown off the old church structures a decade earlier and was still working out what should replace them. The Mass was gone, the monasteries dissolved, the bishop's authority repudiated. But a city can abolish an institution faster than it can build a new one. Bucer looked around his reformed church and saw congregations without real oversight, believers left to drift, and a pastoral office that everyone praised in theory and almost nobody practiced with any rigor. So he wrote a book about it.
The book was called, in its full German title, roughly "Concerning the True Care of Souls and the Right Kind of Shepherd's Service" — and it was not a work of abstract theology. It was a manual. Bucer wanted to say, in concrete and repeatable terms, what a person entrusted with a congregation is actually supposed to do, day to day, with the living souls in front of them. He built the whole thing on a single image the Reformers loved: Christ as the good shepherd, and the pastor as the one who tends the flock in his place. From that image he drew an entire job description.
What makes the treatise worth reading, five centuries later, is how seriously it takes the ordinary work of tending people — not the sermon as performance, but the patient labor of teaching, correcting, comforting, and going after the ones who have wandered off. Bucer treated souls the way a physician treats bodies: something you diagnose, treat, and follow up on. The care of souls, for him, was a craft with methods, and neglecting it was not a minor failing but a betrayal of the whole point of the church.
The question we’re asking : What did Bucer think a shepherd of souls actually owed the people in his care, and why did he treat that duty as sacred rather than optional?What we’ll see : How a working reformer turned the image of the good shepherd into a concrete discipline of tending, correcting, and restoring the human beings of a congregation.
Table of contents
01Chapter 1 — Strasbourg, 1538, and a church that had lost its shepherds
The Reformation had a clarity problem it rarely admitted. It knew exactly what it was against — indulgences, the papacy, a priesthood that mediated grace through ritual. It was much vaguer about what the new church should positively do for the person sitting in the pew. Bucer had spent years in Strasbourg wrestling with practical questions the theological pamphlets skipped over. Who watches over a believer's spiritual life now that confession to a priest is gone? Who notices when someone falls into open sin, or quietly stops coming? Who tends the frightened, the grieving, the doubting?
His answer began with a word: seelsorge, the care of souls. Bucer argued that the church was not primarily a place you attended but a flock that had to be actively tended, and that Christ himself had modeled the work. Scripture, he insisted, was full of shepherd language precisely because tending is what God does with his people — he seeks, gathers, feeds, heals, and guards them. A church that preached grace but left its members untended had kept the theology and dropped the practice.
02Chapter 2 — Five works, one flock: what a pastor actually owes
The organizing move of the treatise is deceptively simple. Bucer takes the flock and sorts it into conditions — much as a doctor sorts patients by what ails them — and then assigns to each condition the specific work it requires. There is the sheep that is lost and must be sought and brought back. There is the one that has strayed from the fold and must be returned. There is the injured sheep that must be bound up and healed. There is the weak one that must be strengthened. And there is the healthy, sound sheep that must be guarded and kept from harm. Five conditions, five works.
From this scheme he derives the duties of the office. The shepherd must bring in those who are entirely outside — the un-churched, the estranged — and lead them to Christ. He must restore those who have wandered into sin or error, going after them rather than waiting for their return. He must heal the wounded conscience, the person crushed by guilt or grief, with the medicine of the gospel applied to their particular wound. He must strengthen the weak in faith through teaching and encouragement so they do not fall away. And he must protect the sound, guarding the whole flock against false teaching and moral danger.
03Chapter 3 — The wandering sheep and the discipline of return
Of the five works, the one Bucer treats with the most care — and the most obvious personal investment — is the restoration of the wayward. Here the treatise turns to the hardest question in any community that takes its own standards seriously: what do you do with the member who has gone wrong? Bucer's answer is neither indulgence nor expulsion but a patient, staged process aimed at one thing — bringing the person back.
He leans on the pattern Jesus lays out in Matthew's gospel: the private word first, then, if that fails, a small gathering of witnesses, and only as a last resort the involvement of the whole community. The escalation matters to Bucer. Church discipline was not, in his hands, a machine for punishment or a purity ritual for casting out the impure. It was medicine with a purpose, and the purpose was healing. Even the final, painful step of exclusion he understood as a shock intended to provoke repentance — a way of taking the wandering seriously enough to alarm them into returning.
04Chapter 4 — When care becomes governance
Step back from the individual duties and a larger claim comes into view. Bucer was doing something more than describing a job. He was arguing that the church is, at its core, a caring institution — a body that takes formal responsibility for the inner spiritual life of every one of its members, and organizes itself to discharge that responsibility. This is a striking thing to assert. Most institutions manage behavior, resources, or membership. Bucer's church claims jurisdiction over souls.
That claim has two faces, and the treatise holds them in tension without fully resolving it. On one face is tenderness: the shepherd who seeks the lost, binds the wounded, strengthens the weak, and knows each sheep by name. On the other is oversight: a church that watches its members, notices their sins, and possesses machinery — private admonition, communal warning, exclusion — to act on what it sees. The same attentiveness that lets a pastor comfort the grieving also lets the institution monitor the strayed. Care and surveillance turn out to be close neighbors, and Bucer was untroubled by their proximity because he trusted the motive to purify the mechanism.
05Conclusion
Bucer wrote his book for a specific church in a specific crisis — a reformed congregation in Strasbourg that had cleared away the old structures and needed to know what tending souls looked like without them. His solution was to take the oldest image in the Christian vocabulary, the good shepherd, and press it until it yielded a working discipline: seek the lost, restore the strayed, heal the wounded, strengthen the weak, guard the sound. The care of souls became a craft with methods and a standard against which any minister could be measured, and mostly found wanting.
