Collect for Trinity Sunday
The Collect for Trinity Sunday is the proper Collect of the Day appointed in the Book of Common Prayer for the feast of Trinity Sunday. In classical Anglican worship it gives concise liturgical expression to the doctrine of the Holy Trinity, praying that worshippers may confess the glory of the eternal Trinity and worship the unity of the divine majesty. Because Trinity Sunday follows the seasons of Advent, Christmas, Epiphany, Lent, Easter, Ascension, and Pentecost, the collect also serves as a doctrinal summary at a turning point in the Prayer Book year.
Text and liturgical use
In the 1662 Book of Common Prayer the collect is appointed for Trinity Sunday and is used with the proper Epistle and Gospel for the day.[1] Its classical wording addresses God as almighty and everlasting, acknowledges divine grace in the confession of true faith, and asks for steadfastness against adversities. The prayer is Trinitarian in subject without being lengthy or speculative. It names the Trinity and the unity of divine majesty, presenting orthodox doctrine in the form of worship.
As a collect, it follows the customary Western pattern of address, remembrance of divine action, petition, and conclusion. In the Prayer Book tradition it is said or sung at Morning Prayer, Evening Prayer, and Holy Communion when the proper collect of the day is appointed. In parish use, it commonly marks the beginning of the long sequence of Sundays after Trinity in the older Prayer Book calendar. Later Anglican calendars often name this period as the Sundays after Pentecost or Ordinary Time, but Trinity Sunday itself remains widely observed across Anglicanism.
Theological themes
The collect is closely associated with the creedal faith of the Church. Its language of confessing true faith and acknowledging divine glory reflects the doctrinal grammar of the Nicene Creed and the broader catholic tradition received by Anglicanism. The prayer does not attempt to explain the mystery of the Trinity by analogy. Instead, it places doctrinal confession inside petition, asking that the faithful may both believe rightly and endure faithfully.
The phrase concerning the Trinity and the unity holds together two central claims of Christian doctrine: God is truly Father, Son, and Holy Ghost, and God is one. This balance is characteristic of classical Anglican formularies, which affirm the doctrine of the Trinity in the Thirty-nine Articles and preserve its regular confession in common prayer. Article I, "Of Faith in the Holy Trinity," states the Church of England's doctrine in formal terms, while the collect gives the same faith a devotional and liturgical shape.[2]
The petition for defence from adversities also gives the prayer a pastoral dimension. Trinity Sunday is not treated only as a doctrinal commemoration, but as an occasion for seeking divine help. The collect suggests that right confession and perseverance belong together: the worshipping Church asks to be kept in the faith it professes.
Place in Anglican tradition
The Collect for Trinity Sunday stands within the wider Western liturgical inheritance received and reformed in the English Prayer Book tradition. Its survival in the classical Prayer Books helped make Trinity Sunday one of the most theologically explicit feasts of the Anglican year. The prayer's compact style is typical of the Prayer Book collects associated with Thomas Cranmer's liturgical revision, though the collect itself belongs to the older Western tradition rather than to a purely modern composition.
In Anglican devotion, the collect has often been valued because it joins doctrinal precision with brevity. It is appointed immediately after Whitsunday, so that the confession of the Trinity follows the celebration of the Holy Ghost's descent at Pentecost. This placement gives the feast a summative character: the saving work celebrated across the first half of the liturgical year is gathered into the worship of the one God, Father, Son, and Holy Ghost.
The collect also illustrates a broader Anglican principle: doctrine is taught not only through formal statements but through repeated public prayer. By hearing and praying this collect annually, congregations encounter Trinitarian theology as part of the normal rhythm of the Church's worship. Its continuing use in traditional-language services, and its influence on modern-language Anglican rites, show its enduring role in the liturgical memory of Anglican churches.
