Collect for the Twenty-First Sunday after Trinity
The Collect for the Twenty-First Sunday after Trinity is a short prayer appointed in the Book of Common Prayer for use at the Holy Communion and in the Daily Office on the twenty-first Sunday after Trinity Sunday and during the following week, where the traditional prayer book calendar permits. Its petition joins forgiveness with peace of conscience, asking that God's people may be cleansed from sin and enabled to serve him with a quiet mind. Within Anglicanism, the collect is often noted as a concise example of the Prayer Book's pastoral theology: pardon is not treated as an abstract legal benefit, but as the ground of ordered Christian service.
Text and Placement
In the 1662 Book of Common Prayer, the collect is appointed among the propers for the long Trinity season. The prayer asks God to grant his faithful people "pardon and peace," so that they may be cleansed from all their sins and serve him with a quiet mind. Like other Sunday collects in the classical Prayer Book, it functions as the Collect of the Day at the Communion service and is also used at Morning Prayer and Evening Prayer when the Sunday collect is repeated through the week.
The position of the collect late in the Trinity season is significant for its reception, though the prayer is not tied to a single historical event in the life of Christ. The Sundays after Trinity traditionally emphasize the moral and spiritual life of Christians after the great feasts of redemption. In that setting, this collect gathers together repentance, assurance, and obedience. Its language is simple, but its structure is characteristically Anglican: it begins with a direct address to God, presents a petition, states the desired moral result, and concludes through Christ.
Theological Themes
The central phrase, "pardon and peace," reflects a recurring Prayer Book concern with the relation between forgiveness and the conscience. The collect assumes that sin disorders the human person and that divine pardon restores the worshipper to a condition in which service is possible. Peace is therefore not merely inward calm, but the settled freedom of those reconciled to God.
The petition that the faithful may be "cleansed" from their sins also places the collect within the penitential grammar of Prayer Book worship. It resonates with the General Confession in Anglican Morning Prayer, the absolutions of the Daily Office and Communion service, and the eucharistic invitation to repentant communicants. Yet the collect is not only penitential. Its final purpose is active obedience: the forgiven people of God are to serve him. The phrase "quiet mind" suggests a conscience no longer driven by fear, distraction, or unresolved guilt, but ordered toward faithful discipleship.
This balance has made the collect useful in Anglican pastoral practice. It avoids separating justification from sanctification, and it does not reduce Christian peace to private feeling. The prayer asks for mercy in order that the Church may offer disciplined service. In that respect it reflects the broader Prayer Book pattern in which doctrine is prayed as well as taught.
Liturgical Use and Reception
In churches using the 1662 Prayer Book or books derived from it, the collect remains associated with the twenty-first Sunday after Trinity. Where modern Anglican calendars follow a different arrangement of Sundays after Pentecost, the collect may appear in traditional-language services, supplemental propers, or devotional use rather than as a fixed Sunday appointment. Its continued use is especially common in communities that retain the classical sequence of Trinity collects.
The prayer's brevity has also helped it endure outside its appointed day. Clergy and laypeople have often used it as a personal prayer before confession, after absolution, or in times of anxiety about sin and duty. Such use is consistent with its original liturgical character, since the collect speaks in the plural for the faithful people as a body, while also addressing the conscience of each worshipper.
For Anglican theology, the collect is a small but representative witness to the Prayer Book's method. It teaches by ordered petition rather than extended definition. In a few clauses it presents God as merciful, the Church as a forgiven people, sin as that from which believers must be cleansed, and Christian service as the fruit of peace with God. Its place in the Trinity season reinforces the Anglican conviction that grace received in worship is to be lived out in ordinary obedience.
