O God of unsearchable wisdom and infinite mercy, who chose a captive warrior, David Oakerhater, to be your servant, and sent him to be a missionary to his own people and to exercise the office of a deacon among them: Liberate us, who commemorate him today, from bondage to self, and empower us for service to you and to the neighbors you have given us; through Jesus Christ, the captain of our salvation; who lives and reigns with you and the Holy Spirit, one God for ever and ever. Amen.
