The Collect is a short opening prayer in a service of worship before the Epistle is read. It may be an invocation, petition, or an affirmation of God’s glory. In the Methodist Church, it is a short prayer with a very precise form. It contains an address to God referring to some attribute of God, a petition relating to that attribute, a reference to the desired results of the petition, and closing words stating that the prayer is through Jesus Christ. The term is derived from the gathering of private petitions from several members of a congregation into a single public prayer. The collectar is a medieval liturgical book containing the collects used in Divine Offices. There are many Collects published in the Episcopal Church’s Book of Common Prayer.
The following Collect for Purity is an ancient prayer.
Deus Cui omne cor patet, et omnis voluntas loquitur, et Quem nullum latet secretum; purifica per infusionem Sancti Spiritus cogitationes cordis nostri; ut Te perfecte diligere, et digne laudare mereamur. Per Christum Dominum nostrum. Amen.
