Today is one of the three winter Ember days on the church calendar. For a really good explanation of what this is click here. In short, it is a day that we remember those persons who have taken holy orders, and pray that others might be called by God to a vocation, whether it be lay or clergy. It is also a good day for every one to consider how God is calling them into deeper relationship.
Almighty God, the giver of all good gifts, in your divine providence you have appointed various orders in your Church: Give your grace, we humbly pray, to all who are called to any office and ministry for your people; and so fill them with the truth of your doctrine and clothe them with holiness of life, that they may faithfully serve before you, to the glory of your great Name and for the benefit of your holy Church; through Jesus Christ our Lord, who lives and reigns with you, in the unity of the Holy Spirit, one God, now and for ever. Amen.
