Sunday after Trinity: Trinity Sunday is a moveable feast and the Advent season is fixed, so the number of weeks in between varies from year to year. Thus, this collect was always read just before Advent - as it in the (pre-reform) Roman Missal whence it came (where the Sunday is called the "24th Sunday after Pentecost", but the Sundays left out after Epiphany are "caught-up" between the 23rd and the 24th, making it always the last before Advent). Since most recipes for Christmas pudding call for the pudding to be kept for several weeks to mature, the day subsequently became connected, in countries which used the Book of Common Prayer, with the preparation of Christmas puddings in readiness for Christmas. Supposedly, cooks, wives and their servants would go to church, hear the words "Stir up, we beseech thee, O Lord ...", and be reminded, by association of ideas, that it was about time to start stirring up the puddings for Christmas. In recent years most provinces of the Anglican Communion have adopted the practice of the Roman Catholic Church in observing this Sunday as Christ the King (sometimes under the name "The Reign of Christ"). Popular attachment to the "Stir up" collect has, however, caused it to be retained (in contemporary language) in the liturgies of several provinces. The Church of England's "Common Worship" uses it as the Post-Communion prayer, with a rubric stating that it "may be used as the Collect at Morning and Evening Prayer during this week". In the Catholic Ordinariates for former Anglicans, Divine Worship: The Missal appoints the "stir up" collect for use on any of the weekdays between the Solemnity of Christ the King which are not themselves Feasts or Obligatory Memorials. The Collect thus functions as the Collect for the Sunday Next Before Advent, even though the Sunday with that title is now a liturgical fiction always being impeded by the higher ranking Solemnity of Christ the King. Yet the fictional Sunday nonetheless provides the real Collect for the following weekdays, as in other weeks in the calendar where a Sunday is occasionally impeded by a higher ranking Feast. The collect thus continues to be used the week before Advent, and thereby ensures that cooks will still be reminded to stir up their Christmas pudding in time, as long as they attend Daily Mass or read the Daily Office on at least
