Fr. Matthew discusses the words of administration that he omitted to discuss last week, and reviews the Lord's Prayer, emphasizing the corporate nature of the Lord's Prayer and the response of 'amen' to the words of administration being our opportunity to confirm our belief in Christ's presence in the Eucharist.
He then focuses on discussion of the Prayer after Communion, a prayer that expresses our thanks for the grace received in the Eucharist, somehow tied thematically to the collect of the day.
The proper prayer after communion is followed by the doxology, a prayer of thanksgiving that starts to turn out prayers from thanksgiving to the question of why we give thanks for what we receive, namely being sent.
