We are followers of Jesus Christ living in joyful, loving fellowship within his Catholic Church through the Ordinariate of the Chair of St. Peter.
The Advent Ember days are four seasonal times of prayer and fasting, and an ancient part of the Ordinariate's English-Catholic patrimony. The word comes from “Quattember” or “the four times of the year” as the Ember days take place in Advent, Lent, Whitsuntide (the season of Pentecost), and September following Holy Cross. The Church invites us to fast and pray for the Lord to send new vocations to ministry in His holy Church, and for Christians to take up bravely their vocations in the world.
The Ordinariate is part of the Roman Catholic Church and follows the ordinary Roman calendar in most respects. However, the Vatican has approved certain liturgical changes that are unique to its English-Catholic patrimony, such as the Ember Days, which are placed in the first week in Advent.
The Advent Ember Day Collects are here:
Ember Wednesday in Advent
GRANT, we beseech thee, Almighty God: that the coming festival of our redemption may obtain for us the comfort of thy succour in this life, and in the life to come the reward of eternal felicity; through Jesus Christ thy Son our Lord, who liveth and reigneth with thee, in the unity of the Holy Spirit, ever one God, world without end. Amen.
Ember Friday in Advent
STIR up, we beseech thee, O Lord, thy power, and come among us: that we, who put our trust and confidence in thy mercy, may speedily be delivered from all our adversities; who livest and reignest with the Father, in the unity of the Holy Spirit, ever one God, world without end. Amen.
Ember Saturday in Advent
O GOD, who seest us to be sore afflicted by reason of the frailty of our mortal nature: grant, we beseech thee, that we may be relieved by thy gracious visitation; who livest and reignest with the Father, in the unity of the Holy Spirit, ever one God, world without end. Amen.
Or, for those to be ordained:
ALMIGHTY God, the giver of all good gifts, who of thy divine providence hast appointed divers Orders in thy Church: give thy grace, we humbly beseech thee, to all who are (now) called to any office and ministry for thy people; and so fill them with the truth of thy doctrine and clothe them with holiness of life, that they may faithfully serve before thee, to the glory of thy great Name and for the benefit of thy holy Church; through Jesus Christ thy Son our Lord, who liveth and reigneth with thee, in the unity of the Holy Spirit, ever one God, world without end. Amen.
Or, for the choice of fit persons for the ordained ministry:
O GOD, who didst lead thy holy Apostles to ordain ministers in every place: grant that thy Church, under the guidance of the Holy Spirit, may choose suitable men for the ministry of Word and Sacrament, and may uphold them in their work for the extension of thy kingdom; through him who is the Shepherd and Bishop of our souls, Jesus Christ thy Son our Lord, who liveth and reigneth with thee, in the unity of the same Holy Spirit, ever one God, world without end. Amen.
Or, for all Christians in their vocation:
ALMIGHTY and everlasting God, by whose Spirit the whole body of thy faithful people is governed and sanctified: receive our supplications and prayers, which we offer before thee for all members of thy holy Church, that in their vocation and ministry they may truly and godly serve thee; through Jesus Christ thy Son our Lord, who liveth and reigneth with thee, in the unity of the same Holy Spirit, ever one God, world without end. Amen.
