The Collect for Purity is a prayer that is commonly used at the beginning of Anglican/Episcopal worship services, including the Holy Eucharist (Communion) and Morning and Evening Prayer.
The prayer dates back to at least the 11th century and has been a part of the Anglican liturgy since the time of the Book of Common Prayer.
Here is the text of the prayer:
“Almighty God, to you all hearts are open, all desires known, and from you no secrets are hid: Cleanse the thoughts of our hearts by the inspiration of your Holy Spirit, that we may perfectly love you, and worthily magnify your holy Name; through Christ our Lord. Amen.”
The prayer acknowledges God as the source of all knowledge and wisdom and asks Him to purify the thoughts and desires of our hearts by the power of the Holy Spirit, so that we may love and worship Him in truth and holiness. It is a prayer of preparation for worship and a reminder of our need for God’s grace and cleansing power in our lives.
